Job Title: Senior Business Analyst (Partner Platform / Payments)
Company: VCG Tech Limited
Location: Remote (Global)
Employment Type: Full-Time

Role Purpose

You will own the requirements, data and acceptance layer for one of our core product areas — either the introducing-broker / partner program or payments (deposits and withdrawals). You turn business, regulatory and operational needs into clear, build-ready specifications: requirements, data models, process and state-flow definitions, API and contract expectations, and the UAT scenarios that prove the system behaves as intended. Because this is a live financial platform where partner commissions and client money are at stake, your specifications and your sign-off are what stand between an idea and a correct, auditable outcome.

Day to day you run discovery with operations, compliance, commercial and finance stakeholders, then translate what you learn into models engineers can build from and testers can verify against. You write working SQL to validate behaviour yourself rather than queueing questions for engineers, read API contracts well enough to challenge trade-offs, and drive disciplined UAT through to a defensible sign-off. You document in Jira and Confluence and keep specifications current as the product evolves. You will be embedded in a focused, remote product team and work closely with its product owner, engineers and QA, reporting into the analysis or product function.

Key Responsibilities

Requirements & Discovery

• Run structured discovery with operations, compliance, commercial and finance stakeholders to surface real needs and constraints
• Translate business, regulatory and operational requirements into clear, prioritised, build-ready specifications
• Define scope, assumptions, edge cases and non-functional expectations, and keep them traceable to delivered work
• Resolve ambiguity early by challenging assumptions and confirming intent before build begins
• Maintain a single source of truth for requirements as the product evolves

Data & Process Modelling

• Model entities and relationships (ERDs) for partner-program or payment data, capturing keys, cardinality and lifecycle
• Specify process and state behaviour with state machines and flowcharts, including failure, retry and reconciliation paths
• Define data contracts and field-level rules so events and records remain consistent across services
• Map end-to-end flows across onboarding, trading activity, payment orchestration or commission attribution at a domain level
• Make implicit business logic explicit so it can be built, tested and audited

API & Solution Collaboration

• Read and review API and event contracts, and articulate expected inputs, outputs and error semantics
• Discuss design trade-offs with engineers and influence solutions without dictating implementation
• Specify integration expectations for internal services and external providers in generic, vendor-neutral terms
• Align requirements with platform realities such as idempotency, eventual consistency and message-driven flows

Validation & UAT Sign-off

• Write working SQL against relational databases to verify behaviour independently of engineers
• Design comprehensive UAT scenarios covering happy paths, edge cases and regulatory and reconciliation checks
• Execute or coordinate UAT, triage findings, and confirm delivery matches intent before release
• Own a disciplined, documented sign-off that holds up to audit and operational scrutiny
• Verify fixes and changes on a live financial platform with appropriate care for data integrity

Documentation & Delivery

• Document requirements, models, decisions and acceptance criteria in Jira and Confluence
• Break work into well-formed tickets with clear acceptance criteria and dependencies
• Keep specifications and process artefacts current through change and iteration
• Communicate status, risks and trade-offs clearly to technical and non-technical stakeholders

Required Experience & Skills

• Senior business analysis experience delivering complex, data-heavy features on transactional or financial systems
• Strong data modelling skills: ERDs, entity lifecycles, and field-level data contracts
• Strong process modelling skills: state machines, flowcharts and end-to-end flow specification, including failure and edge-case paths
• Working SQL against relational databases to query and validate system behaviour independently
• Ability to read and reason about REST API and event-driven contracts and discuss design trade-offs with engineers
• Proven UAT discipline: designing test scenarios, executing acceptance testing, and owning a defensible sign-off
• Excellent requirements elicitation and stakeholder management across operations, compliance, commercial and finance functions
• Clear, precise written documentation using Jira and Confluence
• Comfort working on a live production financial platform where correctness, auditability and data integrity matter
• Self-directed delivery in a remote, cross-functional product team

Nice to Have

• Experience in online trading, CFD/FX, brokerage or broader fintech
• Familiarity with the MetaTrader 5 platform and its data and trading concepts
• Understanding of payment-orchestration concepts such as deposits, withdrawals, settlement and reconciliation
• Familiarity with KYC/AML workflow concepts at a process level
• Understanding of introducing-broker, partner or affiliate programs and multi-level commission or rebate models
• Exposure to microservices and message-driven architectures
• Familiarity with observability tooling (e.g. Grafana, Prometheus, CloudWatch) for behaviour validation
• ISTQB, BCS or comparable business-analysis or testing certification

Job Title: Senior .NET / C# Developer (MetaTrader 5 Integration & Power Platform)
Company: VCG Tech Limited
Location: Remote (Global)
Employment Type: Full-Time

Role Purpose

You will own the integration connector that links our trading platform to the backend systems powering our introducing-broker and partner program. This connector is the source of truth for moving trading and account data out of MetaTrader 5 and into the services that calculate and present partner activity, so its correctness, latency, and resilience directly shape what partners see and how they are rewarded. When this layer is reliable, the rest of the partner experience simply works; when it is not, the impact is immediate and visible, which is why this is a senior, ownership-heavy role.

Day to day you will design, build, and harden .NET/C# services that synchronise data between MetaTrader 5 and our backend, expose it cleanly to the partner platform, and stay healthy under production load. You will work closely with a primarily Java microservices backend team, agreeing on contracts and integration patterns across language boundaries, and partner with product and operations to keep data flows accurate and observable. You will work remotely within a focused product team and be expected to lead technically on everything connector-related, from design through production support. Beyond the connector, you will also extend our Power Platform (Dataverse) CRM with custom C# plugins, applying your .NET skills across both the trading-integration and CRM sides of the platform.

Key Responsibilities

Build and Own the Integration Connector

• Design and maintain .NET/C# services that synchronise trading and account data between MetaTrader 5 and backend systems
• Keep data flows accurate, idempotent, and consistent across sources, handling reconciliation and replay where needed
• Expose clean, well-versioned interfaces so the partner platform can consume trading and account data reliably
• Own the connector end to end, from design and implementation through deployment and production support

Reliability and Resilient Processing

• Engineer for production load with backpressure, retries, timeouts, and graceful degradation
• Implement asynchronous and message-based processing that recovers cleanly from failures and partial outages
• Establish safeguards against data loss, duplication, and drift between MetaTrader 5 and downstream systems
• Diagnose and resolve production incidents, then close gaps with durable fixes and follow-up improvements

Observability and Operations

• Instrument services with metrics, structured logging, and tracing so behaviour is transparent in production
• Define meaningful alerts and dashboards that surface integration health before users feel the impact
• Track latency, throughput, and error budgets, and act on the signals they reveal

Power Platform / Dataverse Plugins

• Build and maintain custom C# plugins for our Power Platform (Dataverse / PowerApps) CRM — server-side business logic, validation, and automation triggered by CRM events
• Integrate the CRM with trading, partner, and payment data so records stay accurate and actionable
• Package, register, and version plugin assemblies and support them to production with the same reliability bar as the connector

Cross-Team Integration and Quality

• Collaborate with a primarily Java backend team to agree on contracts, integration patterns, and data ownership
• Align on REST and messaging conventions that work cleanly across .NET and Java services
• Uphold engineering quality through tests, code review, and CI/CD pipelines
• Document integration behaviour and operational runbooks for the wider team

Required Experience & Skills

• Strong professional experience building production services in .NET / C# (modern .NET)
• Experience building C# plugins for Microsoft Power Platform / Dataverse (PowerApps), or strong server-side C# experience with the readiness to own Dataverse plugin development
• Proven track record designing and operating system-to-system integrations and connectors
• Depth in integration patterns using REST APIs and/or message-based, event-driven processing
• Solid SQL and relational database skills, including modelling for synchronisation and reconciliation
• Hands-on experience with asynchronous and reliable processing: retries, idempotency, backpressure, and failure recovery
• Demonstrated ownership of reliability and observability in production, using metrics, logging, and tracing
• Experience running services on AWS as the primary cloud, including containerised workloads
• Comfort collaborating across language boundaries with a primarily Java backend team
• Strong debugging and incident-resolution skills under production conditions
• Senior-level judgement on design trade-offs, with the autonomy to own a component end to end

Nice to Have

• Experience with the MetaTrader 5 Manager / Gateway API
• Hands-on experience administering or managing a Power Platform / PowerApps (Dataverse) CRM — solutions, model-driven apps, security roles, and Power Automate flows — is a strong plus
• Background in trading, brokerage, or CFD/FX fintech
• Experience integrating .NET services with Java microservices in production
• Familiarity with Docker and Kubernetes for packaging and running services
• Working knowledge of observability tooling such as Grafana, Prometheus, or CloudWatch
• Exposure to infrastructure as code with Terraform
• Experience with CI/CD pipelines and Git-based workflows
• Familiarity with introducing-broker or partner / affiliate program domains

Job Title: Senior QA Engineer (Partner Platform & Payments)
Company: VCG Tech Limited
Location: Remote
Employment Type: Full-Time

Role Purpose

You will own quality for the backend services and web front-ends behind our introducing-broker / partner program and our payments flows — the systems that move client money and calculate the commissions our partners are paid. In this domain correctness is not negotiable: a deposit that posts twice, a withdrawal that stalls, or a rebate that miscalculates erodes trust and has real financial consequence. Your job is to make sure these systems do exactly what they should, every time, across releases.

You will combine test design, hands-on exploratory testing and automation, working close to the code on a Java microservices backend and React front-ends. Day to day you partner with developers, product and other engineers within a focused, remote product team — joining refinement early to shape testability, validating behaviour against databases and event flows, and building the automated coverage that lets the team ship confidently. We work automation-first — using k6 for API and service-level testing and AI-assisted tooling such as Claude Code to move faster — and you will help push that further. You report into engineering and act as the quality voice for your team.

Key Responsibilities

Test Design & Exploratory Testing

• Design test strategies and cases from requirements, acceptance criteria and risk, with money-movement and commission correctness front of mind.
• Run structured exploratory testing to uncover edge cases, race conditions and failure modes automation will not find.
• Define and maintain meaningful test data and scenarios for deposits, withdrawals, referrals and multi-level partner rebates.
• Prioritise testing effort by financial and customer impact, not just feature surface area.

Test Automation & CI/CD

• Write new k6 tests to verify functionality below the UI — exercising APIs, services and event flows directly — and use k6 as the default for anything that is not UI-only, covering both functional and load/performance checks.
• Build and maintain UI / end-to-end automation with modern frameworks such as Playwright or Selenium, reserving browser-level tests for genuinely UI-specific behaviour.
• Make full use of AI-assisted tooling — we actively use Claude Code — to author, extend and maintain tests (including k6 scripts) faster, while owning their correctness.
• Integrate automated tests into CI/CD pipelines so they run on every change and gate releases, keeping suites fast, stable and flake-free with clear pass/fail signals.
• Expand automated coverage of regression-prone areas to steadily reduce manual effort, contributing reusable utilities, fixtures and patterns the wider team can build on.

Data Validation & Backend Verification

• Validate correctness directly against relational databases using SQL, reconciling expected versus actual outcomes.
• Verify event-driven and asynchronous flows, confirming downstream effects and message handling are correct.
• Trace transactions end to end across services to confirm payments and commission calculations hold up.
• Use logs, metrics and observability tooling to investigate failures and pin down root cause.

Defect Management & Reporting

• Raise, prioritise and track defects in Jira with clear reproduction steps, evidence and impact.
• Drive defects to resolution, verifying fixes and guarding against regressions.
• Maintain clear, current test documentation in Confluence so coverage and decisions stay visible.
• Report quality status, risks and trends to the team and stakeholders in plain terms.

Collaboration & Quality Advocacy

• Engage early in design and refinement to improve testability and surface risk before code is written.
• Pair with developers on edge cases, acceptance criteria and automated coverage.
• Champion quality practices across the team and mentor others on testing approaches.
• Continuously refine process, tooling and coverage based on production learnings.

Required Experience & Skills

• 5+ years in QA / test engineering, including senior ownership of quality for backend services and web applications.
• Strong test design skills across manual exploratory testing and structured, risk-based test planning.
• Hands-on API testing experience and the ability to reason about REST services and contracts.
• Proven test-automation experience building and maintaining suites, with hands-on k6 for API / service-level tests (or a comparable scripting/load framework you can transfer to k6), plus UI automation with Playwright or Selenium.
• Comfortable working with AI-assisted coding tools such as Claude Code to speed up test creation and maintenance, with the judgement to verify and own what they produce.
• Proficient SQL for data validation, reconciliation and investigation against relational databases.
• Experience integrating automated tests into CI/CD pipelines and keeping them stable and fast.
• Working knowledge of microservices and event-driven / message-queue architectures, and how to test asynchronous flows.
• Comfortable using logs, metrics and observability tooling to diagnose and root-cause failures.
• Disciplined defect management in Jira and clear test documentation in Confluence.
• Rigorous attention to correctness in systems where financial accuracy is critical, with strong written and verbal communication.

Nice to Have

• Domain experience in online trading, CFDs/FX or brokerage/fintech.
• Familiarity with the MetaTrader 5 platform and trading concepts.
• Experience testing payments flows such as deposits, withdrawals and reconciliation.
• Deeper performance and load-testing experience with k6 (or Gatling, JMeter or similar).
• Exposure to basic security testing and common application security risks.
• Experience testing partner / affiliate or multi-level commission and rebate systems.
• Familiarity with Docker, Kubernetes and AWS.
• Some Java or front-end (React/TypeScript) familiarity to collaborate closely with developers.

Experienced 2nd-Line Support Engineer (Trading Platform)

Company: VCG Tech Limited

Location: Remote (Global)

Employment Type: Full-Time · Evening (17:00–02:00 CET) or Night (01:00–10:00 CET) shift

Role Purpose

As a 2nd-Line Support Engineer, you own the technical investigation and resolution of production issues on a live online trading platform. Sitting between 1st-line support and engineering, you take escalations across the trading, payments, and introducing-broker (IB) / partner systems, reproduce and triage problems, perform root-cause analysis, and drive each issue to a resolution or a clean, well-documented hand-off. In a brokerage where clients trade CFDs/FX in real time and money moves through deposits and withdrawals, fast and accurate diagnosis directly protects client trust and revenue.

Day to day you work hands-on: reading application logs, querying relational databases with SQL to verify what actually happened to an order, payment, or partner record, writing light scripts to gather evidence, and watching monitoring dashboards and alerts to catch issues before clients do. You run incidents calmly, keep stakeholders informed in clear non-technical language, and escalate to engineering only when needed, with findings documented well enough that an engineer can pick up where you left off. You collaborate closely with 1st-line support, product teams, and backend engineers, and you work remotely as part of a distributed support function reporting into engineering/support leadership.

Working Hours & Coverage

This is a shift-based role. We run a three-engineer rota that keeps our support desk covered across extended hours, Monday to Friday, for a live trading platform. We are now hiring for the two shifts:
 

- Evening shift: 17:00–02:00 CET

- Night shift: 01:00–10:00 CET
 

You will be assigned to one of these shifts, and we ask that you state which one you can commit to when you apply. The shifts are designed to overlap by about an hour at each handover, so issues are passed over live between engineers rather than only through written notes. The role is fully remote, but your working hours must reliably and consistently overlap your assigned shift in CET/EET, so we are looking for candidates in compatible timezones. Reasonable rotation between the evening and night shifts, and occasional weekend cover, may apply.

Key Responsibilities

• Escalation Handling & Investigation

- Take escalations from 1st-line support across trading, payments, and partner/IB systems, and own them to resolution or hand-off

- Reproduce reported issues, isolate the failing component, and distinguish user error, data issues, and genuine defects

- Analyse application and service logs to trace transactions end-to-end and pinpoint where behaviour diverged

- Query relational databases with SQL to verify account, order, payment, and partner data against expected state

- Use light scripting (Python/Bash) to collect evidence, parse logs, and automate repetitive diagnostic steps

• Root-Cause Analysis & Resolution
   

- Perform structured root-cause analysis and document a clear chain of evidence for each issue

- Apply known fixes and follow runbooks to resolve recurring problems within the support remit

- Escalate to engineering with concise, well-documented findings, reproduction steps, and supporting data

- Identify patterns across tickets and flag systemic issues, gaps, or fragile areas for permanent fixes

- Contribute to and improve runbooks and knowledge-base articles so resolutions are repeatable
 

• Incident Management & Communication
   

- Act as a calm point of coordination during incidents, driving triage, severity assessment, and timely updates

- Keep stakeholders informed with clear, jargon-free status updates appropriate to a live trading environment

- Coordinate with engineering and product teams to confirm impact, mitigations, and resolution

- Write up post-incident notes and follow-up actions, and track them to closure
 

• Monitoring, Alerting & Ticket Discipline

- Monitor dashboards and alerts to detect and triage issues proactively, before they reach clients

- Maintain disciplined, well-documented ticket handling in Jira with accurate status, context, and history

- Tune and act on alerts, reducing noise and surfacing the signals that matter

- Track recurring issues and feed insights back into monitoring, runbooks, and engineering backlogs

• Required Experience & Skills

- Several years of experience in a 2nd-line, application, or production support role for a live, business-critical software product

- Strong, methodical troubleshooting skills with a proven track record of root-cause analysis under pressure

- Confident writing SQL to investigate and validate data in relational databases (joins, filtering, aggregation)

- Comfortable reading and correlating application logs to trace issues across multiple services

- Hands-on scripting ability in Python and/or Bash for diagnostics, log parsing, and automation

- Practical experience with log and monitoring/observability tooling (e.g. Grafana, Prometheus, CloudWatch or similar)

- Disciplined ticket and incident management, including clear documentation and structured escalation to engineering

- Experience with Jira (or equivalent) and an organised, detail-oriented approach to queue and SLA management

- Excellent written and verbal communication, able to translate technical detail for non-technical stakeholders

- Self-directed and reliable in a remote, distributed team across the full investigate-resolve-handover cycle

• Nice to Have
   

- Domain experience in online trading, CFDs/FX, brokerage, or fintech

- Familiarity with the MetaTrader 5 platform from a support or operations perspective

- Exposure to payments support, including deposit and withdrawal flows

- Understanding of introducing-broker / partner / affiliate programs and multi-level partner commission or rebate concepts

- Basic AWS or general cloud literacy and an understanding of microservices and event-driven systems

- Previous on-call or rota-based incident response experience

- Familiarity with REST APIs and message queues when investigating cross-service issues
