Job description

Metamindz is a fast-growing UK-based IT software company. We help by providing fractional CTOs-as-a-service, building digital products, hiring exceptional technical talent, and conducting tech due diligence for global clients.

We’re currently looking for a Senior Full-Stack Engineer (with a strong focus on back-end) to join one of our clients in a long-term engagement. This is a full-time remote opportunity for a highly senior engineer who is deeply experienced in building complex and scalable systems using NodeJS, TypeScript, Prisma, and PostgreSQL — and who thrives in ownership-driven, product-oriented environments.

Responsibilities

• Architect, develop, and maintain performant full-stack applications using NodeJS, TypeScript, React, and related technologies
• Work with Prisma and PostgreSQL to build and optimize scalable, well-structured database solutions
• Ensure high performance of APIs, queries, and data-intensive operations
• Troubleshoot performance bottlenecks and improve system reliability and scalability
• Collaborate closely with product managers, designers, and other engineers across the stack
• Take ownership of your work and contribute to architectural and technical decisions
• Write clean, maintainable, and well-tested code with a focus on quality and performance
• Contribute to event-driven architecture and asynchronous task processing using tools like BullMQ (nice to have)
• Optionally integrate and experiment with LLMs and other AI tools to enhance product functionality (nice to have)

Requirements

• 7+ years of commercial engineering experience (only truly senior-level candidates will be considered)
• Expert-level proficiency in NodeJS and TypeScript
• Solid experience with ReactJS (even though this role is primarily backend-focused)
• Strong knowledge of PostgreSQL, database modeling, and performance optimization
• Proficiency with Prisma ORM and its ecosystem
• Experience with ElasticSearch or ElasticCache
• Familiarity with background job queues such as BullMQ (nice to have)
• Bonus: exposure to or interest in integrating LLMs (Large Language Models)
• High ownership mentality, architectural thinking, and problem-solving mindset
• Strong communication skills and ability to thrive in distributed teams

What We Offer

• Fully remote, flexible work culture with long-term stability
• Projects with modern tech stacks and high technical standards
• Opportunities to work on meaningful, high-impact platforms
• Transparent, supportive team culture with no micromanagement
• Competitive monthly compensation, commensurate with experience and value

If you're a deeply experienced full-stack engineer with strong backend expertise, looking to work in a fast-paced environment with real ownership — we'd love to hear from you.
