Senior Full Stack Engineer (Backend oriented)

RESPONSIBILITIES

• Architect and extend backend services built in Node.js (Fastify).
• Design and optimize schema, migrations, and queries using SQL + Drizzle ORM.
• Build well-structured, efficient REST APIs used by the front-end console.
• Ensure performance, security, reliability, and scalability of backend systems.
• Work closely with product and engineering to break down technical problems.
• Perform code reviews, advise on architecture, and support scalability decisions.
• Guide frontend engineers in optimal API and data shaping practices.

Ideal Profile

• Has built and scaled real production systems, not just CRUD apps.
• Can explain trade-offs clearly (e.g., SQL vs NoSQL, monolith vs services, caching

strategies).

• Understands how to avoid data overexposure and access boundary issues.
• Able to decompose features into independent components and services.

CLIENT EXPECTATIONS

• Ownership mindset – takes full responsibility for tasks end-to-end, from clarifying requirements to delivering tested, working code.
• Proactive communicator – asks questions early to clear up misunderstandings rather than waiting for code reviews.
• Detail-oriented – ensures features match specifications and are production-ready before submission.
• Collaborative – works closely with the CPO and team, participating in daily standups and sprint planning.
• Adaptable – comfortable working in a fast-moving startup environment where requirements and priorities may shift.
• Efficient and reliable – delivers tasks in small, manageable increments rather than letting them stretch over long periods.
