We’re looking for a strong sales professional with real experience selling virtual card products and Banking-as-a-Service platforms. This person should understand the payments ecosystem well, know how to sell complex financial products, and be comfortable working with fast-moving online businesses.

A big plus is hands-on experience selling to affiliate marketers, media buyers, marketing teams, or clients operating in the performance marketing space.

What we expect:

• Proven experience in B2B sales of virtual cards, payment infrastructure, or BaaS solutions
• Strong understanding of the card issuing / banking / fintech landscape
• Ability to find, approach, and close high-value clients independently
• Confidence in speaking with founders, operators, and decision-makers
• Good understanding of affiliate marketing, traffic teams, media buying, or adjacent industries is a strong advantage
• Fluent English, strong communication, and commercial thinking

What this person will do:

• Build and manage pipeline from outreach to deal closure
• Sell virtual card and fintech infrastructure solutions to relevant clients
• Develop relationships with affiliates, agencies, media buying teams, and other high-volume users
• Work closely with the team on positioning, feedback, and growth opportunities

We need someone commercial, sharp, proactive, and genuinely familiar with this market — not a generic salesperson.

We are looking for a highly experienced Affiliate Marketing professional with a strong reputation, deep industry knowledge, and an extensive network across the affiliate marketing ecosystem.

This is not a traditional Affiliate Manager role.

Your mission will be to build and lead a distributed network of remote Affiliate Ambassadors who can introduce, promote, and sell our product to affiliate marketers, media buyers, affiliate teams, agencies, and other relevant players across the industry.

The Role

We are building a product specifically designed for the affiliate marketing industry and want to scale its distribution through people who already understand this market from the inside.

We are looking for someone who has spent years in affiliate marketing and knows:

• who the serious players are;
• where the strongest affiliate communities are;
• how affiliate teams operate;
• how media buyers make purchasing decisions;
• how relationships and reputation work in this industry;
• and, most importantly, how to recruit people who already have access to these networks.

Rather than building a traditional centralized sales team, you will create a distributed ambassador network consisting of experienced affiliate managers, former affiliate managers, industry connectors, community members, and other well-connected professionals.

Each ambassador will leverage their own relationships and network to generate customers.

Your responsibility is to build this network into a scalable acquisition channel.

What You Will Do

Build the ambassador network

Identify and recruit experienced affiliate managers and other well-connected people across key affiliate marketing markets and communities.

Create the operating model

Define how ambassadors work: territories or communities, lead ownership, attribution, commissions, incentives, reporting, communication, and performance expectations.

Activate existing industry relationships

Use your own network to recruit the first generation of ambassadors and establish credibility for the program.

Train ambassadors

Make sure every ambassador understands the product, its value proposition, ideal customer profile, positioning, objections, and sales process.

Drive performance

Track activity, introductions, qualified leads, conversions, revenue, and ambassador productivity.

Expand internationally

Build coverage across the most relevant affiliate marketing geographies, communities, conferences, agencies, media-buying teams, and traffic verticals.

Create a network effect

Your ultimate goal is not simply to manage affiliates yourself. It is to build a structure where strong people continuously bring in new customers — and where the ambassador network itself becomes a competitive distribution advantage.

Who We Are Looking For

You are likely a strong fit if you:

• Have 5+ years of hands-on experience in affiliate marketing
• Previously worked as a Senior Affiliate Manager, Head of Affiliates, Affiliate Director, Business Development Lead, or similar
• Have an extensive personal network within the affiliate marketing industry
• Personally know affiliate managers, media buyers, team owners, agencies, networks, and other industry decision-makers
• Understand the major affiliate verticals and how their ecosystems differ
• Have attended and built relationships through major affiliate conferences and communities
• Are comfortable recruiting, motivating, and managing people remotely
• Understand performance-based compensation and partner economics
• Can turn personal relationships into a structured and scalable distribution system
• Think like an entrepreneur rather than a corporate employee

What Success Looks Like

During the first stage, you recruit a core group of high-quality ambassadors from your existing network.

You then develop a repeatable model for recruiting, onboarding, activating, and managing them.

As the program scales, we expect to have dozens — and potentially hundreds — of active ambassadors globally, each with access to their own affiliate marketing networks.

The result should be a decentralized sales engine capable of generating a predictable flow of qualified customers.

Why This Role Is Different

We are not looking for someone to manage an existing affiliate program.

We are looking for someone who can build the distribution network itself.

If you have spent years in affiliate marketing, know the right people across the industry, and believe you can turn that network into a global sales force, we want to talk to you.

Your network is the starting point. Your ability to turn it into a scalable organization is the job.

We are looking for a highly connected financial services / international finance professional to build a global network of independent ambassadors and referral partners.

Our clients are businesses and entrepreneurs who need solutions around international payments, crypto-to-fiat / fiat-to-crypto flows, cross-border finance, and international financial structuring.

Your Mission

Build and scale a distributed network of professionals who already advise and influence these clients:

• CFOs and fractional CFOs
• Accountants and accounting firms
• Tax and international structuring advisors
• Corporate service providers
• Crypto / fiat brokers and OTC professionals
• Wealth and financial consultants
• Other trusted intermediaries working with international businesses

Instead of building a traditional sales team, you will turn these professionals into ambassadors who introduce relevant clients from their existing networks.

What You’ll Do

• Recruit the first ambassadors through your own professional network
• Build a repeatable partner recruitment and onboarding model
• Develop commission and revenue-sharing structures
• Train partners on our products and ideal client profiles
• Manage and activate the ambassador network
• Expand the network internationally
• Track leads, conversions, revenue, and partner performance

Who We’re Looking For

You have 5+ years of experience in international finance, payments, accounting, tax advisory, corporate services, crypto/fiat infrastructure, or related industries.

Most importantly, you already have a strong network of CFOs, accountants, financial advisors, brokers, and international business professionals — and know how to turn relationships into a scalable distribution channel.

We're looking for a Lead QA Engineer to own quality across a mobile feed product spanning iOS, Android, and a Go backend. You'll sit in the release path for every feature, bug fix, and A/B variant, making sure nothing ships without being rigorously tested first. This is a hands-on role: you'll be running test suites, managing CI/CD and release tooling, and reading code yourself to understand what actually changed, not just working from a spec. The environment moves fast, so you'll also need to be comfortable smoke-testing incident fixes quickly to unblock releases without cutting corners on safety. You'll work across the full stack, verifying tracking events and A/B test variants on the mobile side while also testing backend behavior in Go. This is a role for someone who wants deep, end-to-end ownership of quality inside a startup that ships constantly.

Details:
Schedule: Full time
Location: Sofia, Bulgaria (Onsite, 5 days a week)
Start: ASAP
Duration: Long-term
English: Fluent

About the project:
The company is building a mobile app with a TikTok-style feed of short, AI-generated browser games created by users. It's an early-stage startup moving at a rapid release cadence, shipping features, bug fixes, and A/B test variants continuously rather than on long cycles. Quality currently rests on how thoroughly each release is tested before it goes out, which is why this role is being built out as a dedicated, owned function rather than something spread thin across the team. The product spans a full stack: mobile clients on iOS and Android, and a Go backend behind them, so testing has to cover both the client experience and the systems underneath it. Because the product runs on experimentation, verifying tracking events and A/B variants correctly is a core part of keeping releases trustworthy. The team is small and fast-moving, so this role carries direct ownership of the release path rather than slotting into an established QA process.

You have:
- Professional QA experience covering both mobile apps (iOS and Android) and backend systems
- Hands-on experience running test suites and working with CI/CD, bug tracking, and analytics tooling — not manual testing alone
- The ability to read and understand code to verify changes, even without writing features yourself
- Ideally, experience QA-ing feature-flagged or A/B-tested mobile products
- Ideally, familiarity with Go or broader backend testing experience
- Ideally, experience with mobile release tooling such as TestFlight or Play Console internal tracks
- Ideally, a background in startups, hyper-casual gaming, or other fast-release-cadence environments
- Willingness to work full-time, strictly on-site in Sofia, Bulgaria

What to do:
- Own quality end-to-end across iOS, Android, and the Go backend
- Run test suites and manage CI/CD and release tooling ahead of every release
- Read and review code changes to understand what shipped and verify it behaves as expected
- Smoke-test incident fixes rapidly to unblock releases while balancing speed with safety
- Verify tracking events and A/B test variants are behaving correctly on mobile
- Build out and improve QA process and tooling as the release cadence and product surface grow

• Strong relational database expertise (PostgreSQL or equivalent), including schema design, ACID transactions, locking, and performance tuning.
• Experience with event-driven architecture and messaging (Kafka, RabbitMQ, or similar), including idempotency and retry mechanisms.
• Strong testing practices, including automated unit, integration, and contract tests as part of the standard development process.
• Hands-on production experience with containers, CI/CD pipelines, monitoring/telemetry, and production incident troubleshooting.
• Solid understanding of multi-threading, system architecture, and fault-tolerant design patterns.
• Good written and spoken English, with experience working effectively in distributed, multi-time-zone teams.

Nice to Have:

• Experience in iGaming, sports betting, fintech, or another regulated, high-transaction-volume domain.
• Exposure to Kubernetes and AWS, including VPC, IAM, EKS, and auto-scaling.
• Experience with compliance-driven development, including KYC/AML, responsible gaming, and audit requirements.
• Experience with AI coding assistants and agentic development workflows.
• Polish and/or Spanish language skills.

Why Us:

We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

We provide full accounting and legal support in all countries we operate.

We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

ABOUT OUR CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Senior Software Engineer for the connectivity stack of a large-scale data platform. The work spans three areas:

• Client connectivity — drivers and client libraries used by applications and BI tools
• Source connectivity — connectors to databases and data systems, including authentication, metadata discovery, and query/data pushdown, with certification and upgrade support
• Agent & service connectivity — tool interfaces and integrations for AI-agent access to the platform

Deep expertise in one of these areas is enough — you'll grow into the adjacent ones over time. This is a role for an engineer who cares about API and protocol stability, backward compatibility, and interoperability with the tools enterprises actually use. You will lead the design and delivery of substantial components, working within an established architecture alongside US-based engineering reviewers.

This is a systems-level, backend engineering role focused on drivers, protocols, and distributed services — not application development or CRUD services.

RESPONSIBILITIES

• Lead the design and delivery of connectivity components — client drivers, source connectors, and service integrations — turning ambiguous initiatives into well-scoped, reviewable milestones
• Produce technical designs, explain architectural trade-offs, and surface compatibility, security, and delivery risks early
• Maintain backward compatibility and API/protocol stability; build compatibility, interoperability, and performance test suites
• Develop and maintain connectors for major BI tools, collaborating with the technology partners behind them
• Diagnose complex client/server, protocol, and distributed-system failures; drive root-cause analysis of customer-reported and escaped defects
• Improve diagnostics, logging, observability, and supportability of the connectivity stack
• Contribute upstream to open-source projects (e.g., Apache Arrow) where agreed
• Mentor engineers, participate in code and design reviews, and communicate progress and risks clearly across a distributed team

REQUIRED QUALIFICATIONS

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 8+ years of production software engineering experience
• Deep proficiency in Java or C++, and the ability to work effectively in another systems/services language
• Experience designing and debugging APIs, protocols, client libraries, or distributed services
• Strong fundamentals: data structures, concurrency, asynchronous programming, networking, and failure handling
• A track record of comprehensive testing — unit, integration, compatibility, and performance
• Experience with production CI/CD, release processes, and engineering quality controls
• Working knowledge of SQL
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• Clear written and verbal communication in a distributed engineering environment; English Upper-Intermediate or higher (B2+)
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

DESIRED SKILLS

• JDBC, ODBC, ADBC, or database-driver development experience
• Apache Arrow (including Arrow Flight)
• SQL engines, databases, or data platforms
• Source-connector development for databases, warehouses, or SaaS systems
• MCP or agent-tool integrations
• OAuth, OIDC, TLS, and enterprise authentication flows
• Cross-platform native build, packaging, and release experience
• BI-tool interoperability (Power BI, Tableau) and partner collaboration
• Observability and production diagnostics
• Open-source contribution experience

DETAILS

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team

About Our Client

About the Role

We are looking for a Senior Software Engineer to build and operate production AI agent and search services on top of a large-scale data platform. This is hands-on work at the intersection of distributed backend engineering and applied AI: multi-agent workflows, tool-execution infrastructure, retrieval and relevance, and integrations with multiple LLM providers — all running as real, customer-facing production services with the reliability expectations that implies.

Responsibilities

• Design and implement scalable multi-agent workflows (including conversation state), tool-execution infrastructure, and data-aware tools working with catalogs, schemas, lineage, SQL, jobs, semantic metadata, data preparation, and visualizations
• Build search and retrieval capabilities with OpenSearch or equivalent — indexing, relevance tuning, hybrid keyword + vector search
• Integrate multiple LLM/model providers with secure configuration and graceful degradation
• Develop APIs and event contracts across REST, streaming/SSE, gRPC, protobuf, and SDKs, including UI integrations
• Operate, monitor, and improve production services — service health, logs, metrics, traces, search-cluster health, latency, and error rates; participate in the team's production-support model
• Investigate incidents, drive root-cause analysis, and ship durable fixes
• Design for permissions, tool approvals, multi-tenancy, and customer-data governance
• Maintain dependencies, apply security fixes, and reduce tech debt; produce designs, tests, runbooks, and documentation; lead technical discussions and review code

Required Qualifications

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 7+ years of relevant experience, or equivalent demonstrated senior-level impact
• Strong Java software engineering skills
• Strong grasp of concurrency, data structures, API design, testing, maintainability, and backward compatibility
• Solid background in distributed systems, microservices, cloud services, or data-intensive backends
• Hands-on experience with search technologies — OpenSearch, Elasticsearch, or Lucene — including vector search, embeddings, or relevance systems
• Experience building LLM applications, agent/tool workflows, RAG systems, or model-provider integrations
• Strong production instincts: diagnosing failures via logs, metrics, and traces; designing for fault tolerance, retries, cancellation, and recovery
• SQL and familiarity with data platform concepts: catalogs, metadata, schemas, governance, lineage
• Comfort leading ambiguous, cross-service work with clear stakeholder communication and strong written documentation
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

• gRPC, protobuf, Quarkus, Kubernetes, MongoDB, KV stores, event-driven architectures
• Apache Arrow, Apache Iceberg, OpenLineage, semantic layers, or data-governance systems
• AI quality evaluation: LLM-as-judge, model benchmarking, production AI metrics
• OpenSearch operations: index lifecycle management, relevance tuning, incident response
• Open-source contributions

Details

• Engagement: Long-term contract
• Location: Europe (EU / EEA / UK), remote
• Working hours: EU business hours, shifted 2–3 hours later for daily overlap with the US West Coast team
