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 or Node.js to a crisp React UI.
What you'll do
•Build end-to-end product features across Go and Node.js/Express backends and React frontend
•AI-assisted development: use Cursor/Copilot/ClaudeCode (or similar) daily to accelerate delivery, refactoring, and test generation—while verifying outputs and keeping 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 where needed) in both Go and Node.js/Express
•Implement frontend flows in React (TypeScript): 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
Must-have experience
•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, debugging
•Hands-on with DDD (not just buzzwords): can model domains and keep boundaries clean
•Strong database skills across PostgreSQL and MongoDB: schema/collection design, indexing, query tuning, migrations
•Experience with GORM and/or Mongoose (or similar ORMs/ODMs) plus comfort dropping to raw SQL or aggregation pipelines when needed
•Frontend proficiency in React (TypeScript preferred), including state management and form-heavy admin UIs
•Good testing discipline (Go testing, Jest/Vitest, 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
