Java Full Stack 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

We’re building the future of AI-powered sales enablement.

PitchSense AI is a flagship product within our portfolio of AI-driven Sales and Marketing solutions.

We blend conversational intelligence, generative AI, and behavioural analytics to help people master persuasion through real-time AI simulations.

Why PitchSense AI

Working here means joining a small, fast-moving team that lives at the frontier of applied AI.

You’ll:

• Build in a high-pace, high-learning environment where ideas ship fast.
• Tinker with cutting-edge AI tools, agents, and large language models (LLMs) daily.
• Prototype novel ways to combine speech, emotion, and reasoning into human-like training experiences.
• Learn across multiple domains — engineering, design, analytics, and product.
• Work directly with the founding team on problems no one has solved before.

This is not routine work — it’s an opportunity to shape entirely new experiences in human-AI interaction while growing faster than you ever have before.
