Podsumowanie oferty

The role focuses on building end-to-end features for a security-first digital asset operations platform. You will work across backend services in Go and Node.js/Express and a React frontend.

Wymagania

Must-have:

7+ years building production systems with Go and/or the MERN stack (MongoDB, Express, React, Node.js), plus solid React experience.
Strong backend fundamentals: concurrency, APIs, reliability, and debugging.
Hands-on experience with DDD, including domain modeling and maintaining clean boundaries.
Strong database skills across PostgreSQL and MongoDB, including schema/collection design, indexing, query tuning, and migrations.
Experience with GORM and/or Mongoose (or similar ORMs/ODMs) and comfort using raw SQL or aggregation pipelines when needed.
Frontend proficiency in React; TypeScript is preferred. Includes state management and form-heavy admin UIs.
Good testing discipline, including Go testing, Jest/Vitest, integration tests, and frontend testing basics.
Confident daily use of AI coding tools such as Cursor or Copilot, with disciplined verification and secure practices.

Nice to have:

Event-driven patterns: outbox, retries, idempotency, and background jobs.
Experience with RBAC/policy engines, audit logs, and fintech/compliance workflows.
Familiarity with Docker/Kubernetes.
CI/CD ownership, including GitHub Actions/GitLab CI and release workflows.
Experience with high-security systems such as custody, payments, or identity.

Obowiązki

Responsibilities:

Build end-to-end product features across Go and Node.js/Express backends and a React frontend.
Use Cursor, Copilot, ClaudeCode, or similar tools daily to accelerate delivery, refactoring, and test generation; verify outputs and keep code clean.
Design backend services using DDD patterns (bounded contexts, aggregates, domain events), clean layering, and pragmatic architecture.
Implement data models and migrations across PostgreSQL and MongoDB, using GORM, Mongoose, or raw queries where appropriate.
Build and maintain REST APIs and webhooks/event-driven workflows in Go and Node.js/Express.
Implement frontend flows in React (TypeScript): dashboards, admin workflows, status lifecycles, and audit views.
Ensure correctness and observability through structured logging, metrics, tracing, and production-ready error handling.
Contribute to security fundamentals: RBAC, least-privilege access, safe secrets handling, and audit trails.
Own quality through unit/integration tests, contract tests, and CI pipelines.

Benefity

Annual performance bonus.
Paid time off, including vacation, sick leave, and public holidays.
