⚡The Vault by Tria Finance is hiring a Full-Stack Engineer (React + Go/MERN)

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: ** ● 5+ 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)

📌 Work format: remote/hybrid/onsite (Limassol office).
