Senior Full Stack Engineer (mainly BE)

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.
