О компании и продукте

• Founded in 2019, Utorg builds the infrastructure for stablecoin payments: on- and off-ramps, self-custodial wallets, and crypto cards. Over 2 million users across 130+ countries already buy, hold, and spend crypto through our app. On the B2B side, the same rails power 2,100+ platforms, with $2.4B+ moved to date.
• Fully MiCA-authorized across the EEA. PCI DSS Level 2 certified. Backed by Dragonfly, TA Ventures, and Hypra.
• Tech stack: TypeScript, Node.js, NestJS, PostgreSQL, TypeORM, NATS JetStream, Redis, Jest, Docker, Kubernetes, Google Cloud Platform.
• Blockchains: EVM-compatible, Bitcoin-family, Tron, Solana, TON.

Задачи

• 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

Требования

• 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
• 5+ years of production experience in backend development with Type Script/Node.js as the primary stack
• 2+ years with NestJS in production — modules, providers, middleware, guards, interceptors, microservice architecture with custom transports
• Deep PostgreSQL expertise — schema design, indexing (partial, GIN/GiST), query optimization, migrations with zero-downtime, database-per-service pattern
• Hands-on microservices experience — not a monolith split into modules
• You’ve dealt with inter-service communication (RPC + pub/sub), message brokers, idempotency, eventual consistency, saga/outbox patterns
• System design experience — decomposing services, designing API contracts, data flow architecture, capacity planning
• You can whiteboard a system and explain why you made each decision
• Complex integration experience — you’ve built and maintained integrations with third-party APIs, payment systems, or similar external services in production
• You know how to handle retries, circuit breakers, and graceful degradation
• Production blockchain experience (MUST-HAVE) — you’ve worked with on-chain transactions, multiple networks, and real user funds
• You understand HD wallets (BIP32/BIP39), smart contracts, ABI, ERC-20/SPL tokens, and the differences between account-based and UTXO models
• Experience with libraries like ethers.js, viem, and solana/web3.js
• AI-driven development (MUST-HAVE) — you actively use AI tools (Claude, Copilot, Cursor) in your daily workflow
• Beyond personal productivity, you have experience optimizing business or organizational processes with AI/LLMs—building automations, internal tools, or workflows powered by language models
• Strong testing discipline — unit tests (Jest), integration tests with real databases, microservice testing
• Security-conscious — in fintech and crypto, every code path can touch real user funds. You build accordingly
• Skilled in technical research — evaluating trade-offs, testing hypotheses, and making data-driven architectural decisions
• English proficiency at Upper-Intermediate. Fluent in the Russian language

Будет плюсом

• Experience with NATS JetStream as a transport layer (streams, consumers, delivery policies)
• Observability: OpenTelemetry, Prometheus + Grafana, structured logging (pino), distributed tracing
• Kubernetes beyond basics: Kustomize/Helm, deployment strategies, resource management
• Fintech domain knowledge: PCI DSS, GDPR, KYC/AML, payment systems
• Experience mentoring junior/middle developers
• React basics for back-office UIs (functional components, hooks, Redux, Material-UI)
• Interaction with other teams
• Close collaboration with Product, QA, Frontend, and Mobile
• Cross-functional communication is an essential part of the role
• Partially offload the Tech Lead: own architectural and technical decisions, independently drive complex integrations, and influence the platform's technical direction
• This is not an executor role
• We need someone with strong expert opinions who can be relied upon for key technical decisions
• Key results (30-60-90)
• 30 days: First features shipped to production
• Deep dive into the stack, architecture, and domain (blockchain, fintech)
• Clear understanding of core services and how they interact
• 60 days: Independently drives a complex integration or a major feature. Participates in architectural code reviews. Brings first proposals for improvements
• 90 days: Makes architectural decisions on their scope
• Influences technical direction
• Partially offloads the Tech Lead in decision-making
• Participates in planning

Условия

• Work fully remote as part of an agile, international team reshaping the future of finance
• An engineering culture that encourages the adoption of modern tools and development practices, giving engineers real influence over technologies, workflows, and technical decisions
• Two career tracks — grow into Tech Lead or deepen your expertise as Staff/Principal IC. You choose the path
• Career progression and professional development in a forward-thinking fintech environment
• Competitive salary range based on individual performance review
• Transparent feedback and a culture that values ownership, open dialogue, and visible impact
