Staff Software Engineer

Matillion is The Data Productivity Cloud.

We are on a mission to power the data productivity of our customers and the world, by helping teams get data business ready, faster. Our technology allows customers to load, transform, sync and orchestrate their data. 

We are looking for passionate, high-integrity individuals to help us scale up our growing business. Together, we can make a dent in the universe bigger than ourselves.

With offices in the UK, US and Spain, we are now thrilled to announce the opening of our new office in Hyderabad, India. This marks an exciting milestone in our global expansion, and we are now looking for talented professionals to join us as part of our founding team.

About the Role

At Matillion, our engineering culture is shaped around small, cross-functional development teams empowered to own specific product themes and initiatives. Each team brings together engineers of all levels, working collaboratively to build, test, and ship impactful features that help our customers solve real-world data challenges.

As a Staff Software Engineer, you will play a key role in driving the technical vision and hands-on development of our platform. You’ll bring deep engineering expertise and a passion for solving complex problems to help us build scalable, performant, and secure software — all while staying at the forefront of cutting-edge technologies, including Generative AI.

• Lead by example: Contribute hands-on to software development, championing high-quality code and robust architecture.
• Drive technical direction: Shape the design and evolution of systems, ensuring performance, security, and scalability.
• Collaborate cross-functionally: Work with engineers, product managers, and customer-facing teams to break down large initiatives into actionable plans.
• Mentor and support: Provide guidance to team members through code reviews, knowledge sharing, and pairing.
• Innovate with AI: Develop intelligent features powered by LLMs (Large Language Models), integrating modern GenAI capabilities into our platform.
• Continuously improve: Proactively explore new technologies, contribute to internal best practices, and help evolve our engineering culture.

• Strong hands-on experience with Java and React, grounded in solid object-oriented principles and software engineering best practices.
• Proficiency in building Java Spring microservices, containerisation with Docker, and experience with relational databases like Postgres, MySQL, or SQL Server.
• Proven track record across the full SDLC, including CI/CD and Agile methodologies.
• Deep familiarity with cloud platforms, especially AWS.
• Ability to adapt to new technologies and solve both product and platform-level challenges in a collaborative team environment.

• GenAI Expertise (Essential)
• Hands-on experience integrating with LLM APIs such as OpenAI, Anthropic, or Hugging Face.
• Understanding of prompt engineering — crafting and tuning prompts to optimize LLM responses.
• Experience with RAG (Retrieval Augmented Generation) to enrich LLM responses with contextual data.
• Familiarity with key LLM concepts: System/User prompts, tokens, embeddings, context windows, temperature, top-p, stop sequences.

• GenAI Experience (Nice to Have)
• Experience with fine-tuning models and prompt compression techniques.
• Exposure to GenAI architectures like prompt chaining, agentic workflows, or routing mechanisms.
• Familiarity with Spring AI or similar libraries that abstract LLM interactions.
• Experience designing and using evals to compare LLM performance and optimize prompts.

Matillion has fostered a culture that is collaborative, fast-paced, ambitious, and transparent, and an environment where people genuinely care about their colleagues and communities.
