Full Job Description

Our vision is to build the world's most intelligent AI legal assistant that can help anyone in the world with their legal problems. We want to build technology that transforms the way lawyers work, helping them navigate complex legal knowledge, move faster, and maximize their impact. We also want to democratize access to legal insights, now made possible through the power of AI. Robin AI has recently raised $26m in Series B funding and has seen an impressive 5x revenue growth in the last 12 months.

We're looking for passionate, resourceful and collaborative people to join Robin. If you're motivated about leveraging technology to make essential business services more accessible, come join us!

About the role

At Robin AI, we bring together amazing people in engineering, AI and the law to create groundbreaking products that are transforming legal teams. Our current product blends traditional engineering, neural networks and LLMs to read and comprehend written contracts, assess whether they adhere to our customers' preferred positions and automatically amends them. But our ambitions go way beyond reviewing contracts; we want to build technology that changes the way people and companies all over the world engage with legal services.

You will help us build software that allows our customers to create contracts from a library of templates; quickly review and edit contracts sent to them by counterparties; and ask critical questions about the contracts they already have.

Our Tech Stack

Our frontend is built using React and Apollo, and we use Python web frameworks, such as Django and Flask, to implement our back-end services, alongside various other services and libraries such as Celery and Elasticsearch. Everything runs on AWS services, including but not limited to ECS, Lambda and SQS. We use CircleCI to build and deploy, and all of our infrastructure is managed using Terraform.

What you'll do

  • Lead the Backend development in a product-focused squad. Make key design and implementation decisions, writing high-quality, well-tested code that solves challenging problems.

  • Work closely with other teams and people, such as Product Managers and ML Research Engineers to deliver great products.

  • Mentor and coach junior engineers in the squad, ensuring best practices are being followed. Play a key role in the recruitment of other Backend engineers at Robin AI.

  • Develop back-end services and GraphQL API's using Django, Flask and similar Python frameworks.

  • Build and maintain the Infrastructure our products and components are deployed to.

  • Identify and prioritise tasks in conjunction with a Product Manager, considering company objectives and goals.

    You enjoy working throughout the backend, and have experience with web-based languages (Python, Go, Node.js) and associated frameworks (e.g. Django, Flask)

  • Have a background working in a start-up or similar size organisation and are passionate about building high-quality products

  • Have an in-depth understanding of the entire development process (design, development and deployment)

    Robin is deliberate about the culture we are building and are committed to creating an inclusive environment that attracts the best talent from diverse backgrounds. Whether it's helping curate the Robin Spotify playlist, discussing gender equality in tech, or taking a meditation break with our holistic health plan, we want you to find your space within the Robin community.


  • From our offices in Liverpool Street, London you'll have access to all of the WeWork amenities including co-working space, bike lockers, pool tables, table tennis, free barista-made coffee and free beer in the evenings.

  • Salary: £110,000-£150,000

  • Generous Equity package: When you help build Robin AI, everyone deserves to be an owner.

  • Please Note: If your salary expectations look a little different to that outlined, we'd still be keen to hear from you if this is a role that excites you.


  • Benefits at Robin AI

    At Robin AI, we put people first; we believe a great product is inextricably linked to a great internal community.

    We're a quickly growing, cross-functional team that values supporting each other's development. As part of the team, you can expect:
  • 25 days PTO plus bank holidays, cultural leave, and birthday leave

  • Unlimited, trust-based sick leave

  • Enhanced gender-neutral parental leave

  • Technology to enable you to work seamlessly from the office or home

  • Focus on continual learning and development

  • Free healthy breakfast on Tuesdays, cinnamon rolls on Thursdays, and a fridge of beverages ordered to request!
