Job description

Owning the end-to-end system architecture (frontend, backend, database, infrastructure) and being accountable for its scalability, resilience, and maintainability.

Making and documenting key technical decisions ‚AI data modeling, API contracts, authorization strategy, concurrency handling, and technology trade-offs.

Designing and guiding the implementation of multi-layered authorization (RBAC + ABAC) that depends on role, department, and task state.

Architecting the Dependency-Aware Task Board, including task state machines and automatic status blocking based on the prerequisites of other tasks.

Defining the strategy for architectural resilience ‚AI Race Condition handling via Optimistic Locking, Soft Deletes, and an Immutable Audit Trail.

Owning Multi-Tenant data isolation and guaranteeing no cross-tenant data leakage across the query, API, and permission layers.

Writing and reviewing production code across the full stack using strict TypeScript ‚AI Next.js 16 (App Router), React 19, and Tailwind CSS 4 on the frontend; Bun, Hono, Prisma ORM, and PostgreSQL on the backend.

Setting and enforcing engineering standards: clean code, code review discipline, modern tooling (Biome, Husky), Conventional Commits, and a solid testing culture.

Owning the CI/CD pipeline (e.g., GitHub Actions) and managing the deployment process of the API and frontend to cloud infrastructure (Vercel, Railway, Render, etc.), including migrations, environments, and rollbacks.

Mentoring and growing engineers through pairing, code review, and technical guidance.

Collaborating closely with Product Management, UI/UX, and fellow Engineers‚AI shaping scope, surfacing technical risk early, and ensuring specifications are met with high quality.
