Job description

We are looking for a high-ownership Full-Stack Engineer / Technical Lead with a strong product mindset and exceptional coding depth. You will architect, build, and scale complex customer-facing applications using React, TypeScript, Node.js/NestJS, and a modern DevEx and testing stack. You should be someone who enjoys solving ambiguous problems end-to-end, thrives in a fast-paced product environment, and cares deeply about code quality, automation, reliability, and system design.

What You Will Do

Engineering & Architecture

• Design and develop scalable full-stack features using React, TypeScript, Zustand, Node.js, NestJS.
• Work across monolithic, microservice, and multitenant architectures with strong understanding of modular design.
• Build robust backend modules using TypeORM/Sequelize, MSSQL, Redis, and modern patterns.
• Implement OpenAPI/Swagger, Zod, and JSON Schema-based contracts for robust typed integrations.
• Leverage AG Grid, MUI, Mantine, Storybook, and design systems to build accessible and maintainable UI.
• Evaluate architectural decisions for performance, scalability, and long-term maintainability.

Quality Engineering & Automation

• Ensure engineering excellence through:
  • Unit tests (Jest, React Testing Library)
  • API tests (Supertest, Jest, Pact where relevant)
  • E2E tests (Playwright)
• Drive engineering best practices: code reviews, static analysis, linting, pre-commit hooks (ESLint, Prettier, Husky).
• Identify and mitigate architectural risks or system-level edge cases early.
• Promote a strong quality culture through automation, tooling, and maintainable code standards.

Collaboration, Leadership & Delivery

• Act as a hands-on technical leader, enabling the team through mentoring, reviews, pairing, and constructive feedback.
• Work collaboratively with Product, Design, QA, and Ops to deliver high-impact features.
• Communicate complex ideas clearly and support decision-making with data and structured reasoning.
• Maintain strong ownership of the full development lifecycle—from requirements to production readiness.
• Contribute to improving tooling, DevEx, observability, and logging using Sentry, GitLab CI/CD, and Vite-based workflows.

Required Skills & Experience

Core Technical Skills

• 9+ years of full-stack development experience in modern web applications.
• Expert-level proficiency in:
  • React + TypeScript
  • Node.js with NestJS and Express
  • State management: Zustand (must have or ability to pick up fast)
  • Testing: Jest, React Testing Library, API testing
  • Database: MS SQL (RDBMS), Sequelize or TypeORM (ideally both)
• Strong experience with:
  • OpenAPI, Swagger, JSON Schema, Zod
  • Microservices + monolithic systems
  • CI/CD pipelines, GitLab, Vite, Sentry, and Redis
• Understanding of:
  • Component-driven UI development with Storybook
  • Performance tuning (frontend & backend)
  • Scalable API design and system reliability
  • Secure coding practices and integration patterns

Nice-to-Have Skills

• Playwright for E2E automation
• GraphQL
• Vega Charts or high-complexity data visualization
• Cursor IDE familiarity
• Experience with multitenancy, domain-driven design, or enterprise product ecosystems

Engineering Mindset & Problem-Solving

We’re looking for someone who:

• Thrives in incomplete or evolving problem spaces and can drive structured solutions.
• Thinks end-to-end across frontend, backend, database, and infrastructure layers.
• Understands the product impact of engineering choices.
• Demonstrates curiosity, continuous learning, and eagerness to work with new tools.
• Provides feedback with clarity, tact, and fairness—and is equally open to receiving it.
• Balances speed with high engineering quality and long-term maintainability.

Soft Skills

• Excellent communication and analytical skills.
• Strong ownership mentality and self-driven work ethic.
• Highly collaborative, team-first attitude.
• Ability to lead technical discussions and mentor others.
• Fluent in English.
• Structured, methodical problem-solving approach.

Why Join Us?

• Work on a modern, high-scale, customer-facing product ecosystem
• Solve challenging engineering problems in a collaborative team
• Build with one of the most modern front-end and back-end stacks
• High autonomy, great learning opportunities, and support for innovation
