Job Title: Senior Java Team Lead (Payments)
Company: VCG Tech Limited
Location: Remote (Global)
Employment Type: Full-Time

Role Purpose

You will lead the team that builds and runs our payments platform, the systems that move client money in and out of an online trading business. This covers deposit and withdrawal orchestration, integration with multiple third-party payment service providers, payout flows, and reconciliation. This is money-movement software, so correctness, idempotency, traceability and reliability are the standard, not aspirations. You own the architecture, the technical direction and the delivery accountability for a domain where a single mishandled transaction is a real problem for a real client.

This is a hands-on, coding team lead role. You will spend meaningful time in a Java and Spring Boot microservices codebase, with enough React and TypeScript to lead a fullstack team across the payment journeys clients and operations staff actually use. Day to day you balance writing and reviewing code, shaping the architecture, and growing the engineers around you, working closely with product, operations and other engineering teams to ship reliable payment flows. The team works remotely and you report to the CTO.

Key Responsibilities

Architecture and money-movement correctness

• Own the architecture of deposit, withdrawal, payout and reconciliation services across a Java microservices backend
• Design transaction flows that are idempotent, auditable and safe under retries, timeouts and partial failures
• Define how state transitions, ledgering and reconciliation guarantee that money is never lost, duplicated or stranded
• Set the standards for data consistency, event-driven messaging and failure handling across the team
• Drive technical decisions on resilience, observability and recovery for critical payment paths

Hands-on delivery

• Write, review and merge production code in Java and Spring Boot, leading by example on quality
• Build and maintain REST APIs and event-driven integrations between payment services
• Contribute to the React and TypeScript front end for client and operations payment journeys
• Keep CI/CD, automated testing and deployment pipelines healthy and fast
• Tackle the hardest or highest-risk parts of the work yourself when it matters most

Provider integration and reliability

• Lead integration with multiple third-party payment service providers behind a clean internal abstraction
• Design provider routing, fallback and retry behaviour that stays correct when a provider degrades or fails
• Build reconciliation between internal records and provider settlements to detect and resolve discrepancies
• Own monitoring, alerting and on-call readiness for payment flows using observability tooling
• Lead incident response for payment issues and turn root causes into lasting fixes

Team leadership and delivery

• Lead, mentor and grow a team of backend and fullstack engineers
• Own planning, prioritisation and delivery commitments for the payments roadmap
• Run pragmatic code review, design review and engineering practices that keep quality high
• Partner with product, operations and other teams to translate needs into reliable delivery
• Be accountable for the team's output, timelines and the operational health of what you ship

Required Experience & Skills

• Proven team-management experience is essential - you have directly led a team of engineers as their team lead, owning day-to-day coordination, planning, 1:1s, mentoring, performance and growth, and the team's delivery, while remaining hands-on with code
• 8+ years building backend systems in Java, with deep Spring Boot and microservices experience
• Strong track record building systems where correctness and reliability are critical, ideally involving money movement, transactions or other high-integrity data
• Practical mastery of idempotency, retries, distributed transactions and failure handling in distributed systems
• Strong SQL and relational database skills, including data modelling for transactional and reconciliation workloads
• Hands-on experience with event-driven architectures and message queues
• Experience designing and operating REST APIs and integrating with third-party providers at scale
• Working proficiency in React and TypeScript, enough to lead a fullstack team and contribute to the front end
• Solid experience running services on AWS with Docker, CI/CD and Git-based workflows
• Clear communicator who can drive technical decisions and align engineering with product and operations

Nice to Have

• Experience in payments, payment orchestration or integrating multiple payment service providers
• Background in reconciliation, ledgering or settlement systems
• Experience in fintech, brokerage or online trading domains
• Familiarity with KYC/AML and fraud-prevention concepts at a generic level
• Kubernetes experience for deploying and operating microservices
• Infrastructure-as-code experience, for example Terraform
• Hands-on experience with observability tooling such as Grafana, Prometheus or CloudWatch
• Comfortable working in a remote, product-team-oriented engineering organisation

About the product

SignalsAPI sells verified hiring signals. You give the API a company or a market, and it returns which companies are actively hiring for a given role right now — read directly from company ATS feeds (Greenhouse, Lever, Ashby, Workday), not guessed from an intent model. 450+ sources, around 2M signals a month, refreshed every three hours. The API, the product and the billing are all live.

This is a small operation. I built the product and I run it. You would work directly with me, with no layers in between — fast decisions, no bureaucracy, and no ready-made playbook. The first months are about finding what works.

The role

Everything technical is finished. What the product does not have is a repeatable way of reaching buyers. That is the job.

Who we sell to:

• RevOps and GTM leads at B2B companies that already do signal-based selling
• Owners of recruitment and staffing agencies in the UK, EU and US

Plans run EUR 79–399/month, with larger custom contracts above that.

What you will do:

• Build and maintain sending infrastructure: domains, mailboxes, warmup, SPF/DKIM/DMARC, LinkedIn accounts operating inside safe limits
• Build target audiences. I have a list of about 40 competitors and adjacent vendors; the people who follow and engage with them on LinkedIn are the first audience. RevOps and GTM titles are the second. Staffing agency owners are the third
• Run the tooling — Apollo, Instantly, Lemlist, Smartlead, HeyReach, Expandi, Clay, or whatever you know well. I pay for subscriptions
• Write and test outreach sequences in English. I supply positioning, proof points and technical detail, and I review copy before it goes out
• Report weekly: sent, reply rate, positive reply rate, meetings booked — split by audience and by signal type
• Book meetings into my calendar. I run the calls

What I am looking for:
 

• 2+ years in B2B lead generation or SDR work, with campaigns you personally built and sent
• English strong enough to write outreach read by native speakers in the UK and US. I will edit, but I cannot rewrite everything
• You can explain how a sending domain gets burned and how to avoid it
• You understand what GDPR means for outbound in Europe. I run a UK company selling into the EU and UK
• You are comfortable being measured on replies and meetings rather than on messages sent

Nice to have:
 

• Experience selling a product rather than outsourcing services
• Familiarity with the recruitment and staffing market
• Comfort with APIs and webhooks. My own product is a signal source, and feeding it back into our own outbound is an obvious thing to do

Conditions

• Remote, flexible hours, three hours of overlap with Central European Time
• Part-time, around 25 hours a week to start. Full-time possible if it works
• B2B contract with a UK company, monthly invoice, you handle your own FOP reporting
• One month probation with a clear goal: infrastructure live and the first campaign sending inside two weeks

Hiring process

1. Application with the control questions answered
2. A 40-minute call
3. A paid test task, 3–4 hours, paid at your rate whether or not I hire you
4. Offer

I answer every application.
