Job description

We are looking for a robust Product Engineer to build the operational backbone system that manages deliverables for high-value projects. This role is not just about building simple CRUD applications; it requires a deep understanding of complex system architectures, including the enforcement of State-Based Permissions, Inter-Task Dependencies, and the prevention of Data Concurrency Conflicts. You will work in a collaborative workflow alongside a multi-disciplinary team to produce a resilient and scalable product.

Core Responsibilities

Developing and maintaining type-safe product applications using strict TypeScript on both the frontend and backend.

Building responsive, dynamic, and integrated user interfaces using a modern ecosystem: Next.js 16 (App Router), React 19, and Tailwind CSS 4.

Designing and implementing efficient and secure APIs using the Bun runtime, Hono, Prisma ORM, and PostgreSQL database.

Handling edge-cases and advanced architectural resilience, including Race Condition scenarios through Optimistic Locking, as well as implementing Soft Deletes and an Immutable Audit Trail.

Implementing complex business logic such as multi-layered authorization (RBAC + ABAC) that depends on role, department, and task state.

Building a Dependency-Aware Task Board where a task's status can be automatically blocked based on the prerequisites of other tasks.

Collaborating closely with Product Management, UI/UX, and fellow Engineers to ensure feature specifications are met with high quality.

Managing the deployment process of the API and frontend to cloud infrastructure services (such as Vercel, Railway, Render, etc.).

Job Requirements

Proven experience as a Product Engineer or Software Engineer focusing on complex web-based applications.

Deep expertise in the Frontend stack: Next.js (App Router), React, TypeScript, and styling using Tailwind CSS & Radix UI / shadcn.

Experienced in state management and data fetching using TanStack Query 5 and Zustand 5.

Strong understanding of the Backend stack: Bun, frameworks like Hono, ORM (Prisma), and relational databases (PostgreSQL).

Accustomed to designing efficient database schemas, creating entity DTOs, and handling solid data validation using Zod.

Strong understanding of JWT-based authentication, session management, and API security.

High-level analytical and problem-solving skills, particularly related to Multi-Tenant data isolation and concurrent data synchronization (concurrency).

Disciplined in writing clean code, and familiar with modern tooling standards (Biome, Husky) and neat version control workflows (Conventional Commits).

(Bonus) Experience in setting up CI/CD pipelines (e.g., GitHub Actions) and writing unit tests for services and UI components.
