Role Overview 🔎

We're open to speaking to engineers with different levels of seniority from Intermediate to Senior/Principle as we've launched a new product which is delivering much needed transparency to the home buying process, with a view to transforming the way property is transacted. We have a successful existing product which helps real estate professionals extract key information & create reports from legal documents. We’re evolving this product to add further value to our user base. 

With the recent release of many large language models (LLMs), such as OpenAI’s GPT-4, we’ve pivoted to using them and this is an opportunity for someone who is passionate about learning how to use this brand new technology in production use cases.

You’ll own the end-to-end design and development of key features of our web application along with the underlying services and infrastructure that support it. You’ll be joining a small, dynamic and fast-paced team with a focus on quality, usability and impact. You’ll be involved in every stage of the development lifecycle; from discovery and design, through implementation to deployment, maintenance and continuous improvement. You will be supported by a cross-functional, collaborative and growing team in delivering an impactful product, initially to lawyers and then to a wider set of B2B customers.

You’ll get a chance to: 👩‍💻 👨‍💻

  • Take ownership of key technology decisions and lay the groundwork for the company’s ambitious growth plans
  • Develop, test, refactor, deploy, maintain and support production software
  • Collaborate with a cross functional team (an AI product manager, a legal domain expert, data scientists and software engineers) to define user stories, quickly experiment and ship new features along with implementing both functional and non-functional requirements
  • Champion quality and reuse across the product and the codebase
  • Collaborate with individuals across the business to ensure the features you develop have real business impact for customers and actually move key business metrics as we design and build a brand new product that doesn't yet exist in the market
  • Participate in architecture and code reviews to continuously improve the quality, maintainability, security and scalability of our applications

You should apply if you: ✍️

  • Have a keen interest in AI tool use, multi-agent architectures, RAG systems, planning and long-running tasks, and prompt engineering
  • Have experience with backend development - ideally Python but not required
  • Have experience with frontend development - ideally React, TypeScript and/or Next.js
  • Value shipping early and often to get customer feedback and then iterating quickly to improve the product
  • Have excellent verbal and written communication skills in English
  • Have proven experience delivering large, complex software engineering systems

It would also be nice if you have:

  • Experience working with LLM’s and OpenAI's API in particular
  • Experience building applications with Docker and Kubernetes
  • Built highly secure, fault tolerant APIs
  • Experience building high performance, distributed systems at scale
  • Proven experience of driving and using modern dev practices like 12 Factor, CI/CD, etc.


  • Competitive starting salary of £70k - £90k
  • Matched pension contributions
  • Equity options in a fast growing start-up
  • Flexible working hours and location; should you choose to work from home or need a change of scenery for a few days you will have access to offices in The Boutique Workplace Company, in and around London
  • 25 days paid holiday (plus bank holidays)
  • Professional equipment and personal development budget along with training opportunities to learn and develop your skills
  • Cycle-to-work scheme
  • An inclusive community enjoying all-company off-sites, lunches and socials
  • Spill - an all-in-one mental health support app through Slack

💡 We value diversity at Orbital Witness, and would particularly encourage applications from those who are traditionally underrepresented in tech. We’d love to hear from you even if you don’t match all of the above criteria or are seeking other opportunities that we’re not currently advertising.
