About the role:

We're looking for a Senior Backend Engineer who thinks in systems and owns the outcome: two large-scale microservice platforms (30+ and 25+ services), blockchain integrations handling real user funds across multiple networks, a fintech product available in 190+ countries.

This role exists to partially offload the Tech Lead. That means making architectural calls independently, driving complex integrations with payment providers and blockchain networks, and shaping technical direction, so not just contributing to it.

The bar is high by design. If you've been in rooms where key technical decisions get made, and you were the one making them or should have been, let's talk.
What you’ll do:

- Own backend architecture across two large-scale microservice platforms (30+ and 25+ services) from system design and API contracts to data flow and inter-service communication.

- Lead complex integrations — payment providers, card issuers, blockchain networks, third-party APIs, and take full responsibility for their reliability in production.

- Drive performance and scalability — identify bottlenecks, design caching strategies, optimize database queries, and ensure the platform handles growing load.

- Shape technical direction — make architectural decisions, evaluate trade-offs, and influence the team’s engineering standards. You’ll partially offload the Tech Lead so the team can scale.

- Build and improve AI-powered processes — our team actively uses LLM-based systems to automate operational and development workflows. You’ll contribute to and extend this direction.

- Contribute to back-office frontends (~20% of your time) — maintain and extend React-based admin dashboards used by internal teams.

- Own features end-to-end from planning and architectural design to implementation, testing, production monitoring, and iterative improvement.

- Collaborate closely with Product, QA, and cross-functional teams — produce clear technical documentation, participate in code reviews, and share knowledge.

- Take part in a shared on-call rotation — roughly one week a month.

Who you are:

-
Technically strong with an architectural mindset — you don’t just write code; you design systems. You think about data flows, failure modes, and long-term maintainability before writing the first line.

-
Opinionated and able to defend your decisions — you bring an expert perspective to technical discussions and can articulate trade-offs clearly to both engineers and stakeholders.

-
Proactive problem-solver — you find issues before they become incidents and propose solutions without waiting to be asked.

-
Product-driven — most of your time goes into shipping features and solving real user problems, not open-ended refactoring.

-
Self-motivated and responsible — you thrive in small teams, enjoy autonomy, and take full ownership of the development process.

What you will bring (must-have) :

-
Last 5+ years of production experience in backend development with Type Script/Node.js as the primary stack.

-
Last 2+ years with NestJS in production — modules, providers, middleware, guards, interceptors, microservice architecture with custom transports.

-
Production blockchain experience — you’ve worked with on-chain transactions, multiple networks, and real user funds. You
