Full-Stack Engineer (Go + React)

About us: We build a security-first platform for digital asset operations. Our product is API-driven, highly auditable, and engineered for reliability. We’re looking for a senior full-stack engineer who can own features end-to-end: from clean domain modeling in Go to a crisp React UI.

What you’ll do: ● Build end-to-end product features across Go backend and React frontend ● Design backend services using DDD patterns (bounded contexts, aggregates, domain events), clean layering, and pragmatic architecture ● Implement data models and migrations on PostgreSQL, using GORM where appropriate (and raw SQL when it’s the right tool) ● Build and maintain REST APIs (and webhooks/event-driven workflows where needed) ● Implement frontend flows in React (TypeScript preferred): dashboards, admin workflows, status lifecycles, audit views ● Ensure correctness and observability: 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: unit/integration tests, contract tests, and CI pipelines ● AI-assisted development: use Cursor/Copilot (or similar) daily to accelerate delivery, refactoring, and test generation—while verifying outputs and keeping code clean

Must-have experience: ● 5+ years building production systems with Go and React ● Strong backend fundamentals: concurrency, APIs, reliability, debugging ● Hands-on with DDD (not just buzzwords): can model domains and keep boundaries clean ● Strong PostgreSQL skills: schema design, indexing, query tuning, migrations ● Experience with GORM (or similar ORM) plus comfort dropping to SQL when needed ● Frontend proficiency in React (TypeScript preferred), including state management and form-heavy admin UIs ● Good testing discipline (Go testing, integration tests; frontend testing basics) ● REQUIRED: confident daily use of AI coding tools (Cursor/Copilot/etc.) with disciplined verification and secure practices

Nice to have: ● Event-driven patterns: outbox, retries, idempotency, background jobs ● Experience with RBAC/policy engines, audit logs, fintech/compliance workflows ● Docker/Kubernetes familiarity ● CI/CD ownership (GitHub Actions/GitLab CI), release workflows ● Experience with high-security systems (custody, payments, identity)

Soft skills: ● Ownership mindset: deliver features end-to-end with high quality ● Clear communication and ability to work across teams ● Pragmatic: balances long-term design with shipping ● Comfortable in ambiguity and fast iteration
