Fullstack Developer

We're a small, high-output technology consultancy based in London, building AI-powered platforms for the construction and real estate industry. We work with enterprise clients and develop our own products. You'll be building real things that ship.

We're looking for a full-stack developer who has hands-on experience integrating AI into products - not just someone who's done a tutorial on LangChain, but someone who's actually built features powered by LLMs, embeddings, or AI APIs and shipped them to real users.

What you'll do

Build and maintain full-stack web applications using React/Next.js on the frontend and Node.js or Python on the backend

Integrate LLM APIs (Claude, OpenAI, etc.) into production workflows — including prompt engineering, structured outputs, tool use, and retrieval-augmented generation

Work with MCP (Model Context Protocol) servers and AI agent architectures as part of our platform integrations

Design and build APIs that connect AI capabilities to user-facing features

Contribute to data pipelines that feed AI systems — document parsing, embedding generation, vector storage

Work directly with the team on architecture decisions — no layers of project managers

What we're looking for

3–8 years of professional full-stack development experience

Strong React/Next.js and Node.js or Python (ideally both)

Genuine, demonstrable experience integrating AI/LLM capabilities into a product — tell us what you built, how the AI was used, and what you learned

Familiarity with at least some of: LangChain, LlamaIndex, vector databases (Pinecone, Weaviate, pgvector), embedding models, RAG pipelines, prompt engineering patterns

Comfortable with REST APIs, PostgreSQL, and modern deployment (Docker, CI/CD)

Exposure to or interest in MCP (Model Context Protocol), AI agents, and tool-use patterns is a strong plus

Solid written English — you'll be communicating daily with a UK-based team via async standups and weekly video calls

Willingness to overlap with UK hours for at least 4–5 hours daily (roughly 1:30 PM – 6:30 PM IST)

Product company or startup background preferred over services/outsourcing firms

What we offer

Cutting-edge AI and LLM work — not a legacy codebase

Exposure to MCP integrations, Claude API, and modern AI tooling before most developers even hear about it

Potential for long-term engagement with room to grow into a tech lead role

Flexible hours outside the overlap window

One paid day off per month

Responsibilities: 

• Develop and maintain high-quality, efficient, and scalable backend applications. 
• Participate in all phases of the software development lifecycle (SDLC) 
• Write clean, well-documented, and testable code adhering to best practices. 
• Collaborate with team members to ensure the successful delivery of projects. 
• Debug and troubleshoot complex technical problems. 
• Identify and implement performance optimizations. 
• Participate in code reviews 
• Hands-on experience with Springboot, Java 8 and above. 
• 5-7 years of experience developing Java applications. 
• Knowledge about at least one messaging system like Kafka, RabbitMQ etc. 
• Required React developer requirements, qualifications & skills: 
• Proficiency in React.js and its core principles 
• Strong JavaScript, HTML5, and CSS3 skills 
• Experience with popular React.js workflows (such as Redux) 
• Strong understanding of object-oriented programming (OOP) principles. 
• Experience with design patterns and best practices for Java development. 
• Proficient in unit testing frameworks (e.g., JUnit). 
• Experience with build automation tools (e.g., Maven, Gradle). 
• Experience with version control systems (e.g., Git). 
• Experience with one of these databases – Postgres, MongoDb, Cassandra 
• Knowledge on Retail or OMS is a plus. 
• Experienced in containerized deployments using Docker, Kubernetes and DevOps mindset 
• Ability to reverse engineer existing/legacy and document findings on confluence. 
• Create automated tests for unit, integration, regression, performance, and functional testing, to meet established expectations and acceptance criteria.
