Senior JavaScript Full Stack Engineer

About the role

We are seeking a versatile Senior JavaScript Full-Stack Engineer to join our global engineering team. In this role, you will play a pivotal part in architecting and building high-performance, “Zero-to-One” products for some of the most innovative technology companies in Silicon Valley and beyond.

You will work alongside a community of senior experts, tackling complex technical challenges in a remote-first environment. Our focus is on fostering a culture where clean code, scalable architecture, and continuous learning are at the forefront. We don’t just offer a position; we offer a platform for you to work on sophisticated tech stacks that define the future of the industry.

What you will do

• Design and implement high-concurrency, scalable back-end services using Node.js and modern frameworks (NestJS, Express, or Fastify);
• Create responsive, user-centric front-end experiences using React.js and its ecosystem (Redux/Zustand, Context API, Hooks);
• Take full ownership of the development lifecycle—from initial concept, analysis, and estimation to architecture, deployment, and maintenance;
• Work directly with US-based product owners and stakeholders to translate business requirements into technical reality;
• Participate in code reviews and share your expertise to help elevate the technical standards of the entire team.

Must haves

• 5+ years of professional software engineering experience, with a deep focus on Node.js and the JavaScript ecosystem (Event Loop optimization, asynchronous programming, and middleware);
• Deep familiarity with software engineering principles and best practices (SOLID, DRY, and design patterns), and a solid understanding of how modern JS frameworks utilize them (e.g., Dependency Injection in NestJS);
• Solid experience with React.js and TypeScript. You should be comfortable building type-safe components and managing complex application states;
• Proficiency in both Relational (PostgreSQL, MySQL) and NoSQL (MongoDB, DynamoDB, Redis) databases;
• Hands-on experience with AWS, Azure, or GCP, along with a strong understanding of CI/CD pipelines, Docker, and Kubernetes;
• Proven experience with Microservices architecture, Event-Driven design, and robust RESTful/GraphQL API design;
• Upper-Intermediate to Advanced English (both written and verbal) for seamless collaboration with global teams.
