Software Engineering
Salt Lake City, UT, USA
Posted on Monday, March 11, 2024

Your work will change lives. Including your own.

At Recursion we combine experimental biology, automation, and artificial intelligence to quickly and efficiently identify treatments for human diseases. Today we have four drugs in the clinic, and in the next 10 years we hope to discover 100 more. We are transforming drug discovery into a data science problem, and to do that we are building a platform for rapid biological experimentation, data generation, automated analysis, model training, and prediction.

The Impact You’ll Make

  • Build production-grade tools and APIs to query petabytes of biological data and AI models. You will play a role in building the tooling that gets our proprietary data and technologies from the lab to our partner-facing apps automatically and efficiently in the context of a production-grade cloud product.
  • Create delightful user experiences meeting drug discovery scientists' needs. Our tools need to help scientists generate disease treatment hypotheses without getting in the way. You will partner with scientists to understand their workflows and build world-class data-centric user experiences enabling them to work as efficiently as possible
  • Lead the way in designing, architecting and implementing the next generation of LLM-enabled software for drug discovery. We believe LLMs are powerful reasoning engines that will drastically change the way companies build and deliver software. You will embrace this paradigm shift and be at the forefront of the large language models revolution. On top of solving the traditional technical challenges of building a product on the cloud, you will be faced with modern technical problems in embedding AI-first and LLM-first features in our platform
  • Every Recursion engineer acts as a mentor, coach, and sponsor. You will share your technical knowledge and experiences, increasing learning, growth, and impact within and beyond your team

Location: This is a hybrid position based out of our office in London, UK

The Team You’ll Join

This role supports LOWE – our proprietary product that orchestrates complex drug discovery workflows via a natural language interface and interactive graphics. At the forefront of LOWE's functionality is its ability to integrate with the Recursion OS. This includes access to petabytes of proprietary data and specialized computational tools tailored for drug discovery. This is your opportunity to lead a paradigm shift in the industry and accelerate delivering therapeutics to patients. We are looking for people who will help us build out an enterprise, industry-changing product.

You’ll be developing a full stack of software and tools, including user interfaces with behavior-based and user-centered designs, RESTful APIs, event streaming, data manipulation, and third-party integrations - seeking and providing feedback and making trade-offs as you go to get to the right solution with the right amount of effort.

The Experience You’ll Need:

  • At least 5 years experience collaborating on technical teams to complete large projects. We don't have much in the way of project managers so you need to work in an Agile environment and be an effective communicator with the team and stakeholders
  • Enthusiasm and ability to contribute equally to frontend and backend parts of a software system
  • At least 5 years of experience with production-grade solutions with a balance of frontend and backend technologies such as the Python programming language and its ecosystem for backend & data engineering use cases and TypeScript+React.js or Next.js for frontend use cases
  • Demonstrated ability to thrive and stay organized in a fast-paced environment
  • Relevant experience building LLM applications and systems
  • 5+ years experience in delivering cloud-based products, preferably using the Google Cloud Platform and GKE, and having been exposed to several facets of the whole system
  • You have a strong desire to learn and adapt. Particularly, you are excited about the intersection between machine learning, software, and life sciences
  • Excitement to learn parts of our tech stack that you might not already know. Our current tech stack primarily consists of Python, React (both JavaScript and TypeScript), PostgreSQL, Kafka, and Kubernetes, on cloud services provided by Google Cloud Platform

How You’ll be Supported

  • You will join and actively learn in an amazing community of engineers and scientists in the fields of ML, software, data, biology, chemistry, and more
  • You will contribute to conference publications and have the opportunity to attend major ML conferences
  • You will be provided opportunities to share your work and teach others new skills, and learn from a wide range of experiences of others both in and outside of your field of expertise
  • You will have the option to participate in coaching programs like BetterUp for leadership skills and development programs.


The Values That We Hope You Share:

  • We Care: We care about our drug candidates, our Recursionauts, their families, each other, our communities, the patients we aim to serve and their loved ones. We also care about our work.
  • We Learn: Learning from the diverse perspectives of our fellow Recursionauts, and from failure, is an essential part of how we make progress.
  • We Deliver: We are unapologetic that our expectations for delivery are extraordinarily high. There is urgency to our existence: we sprint at maximum engagement, making time and space to recover.
  • Act Boldly with Integrity: No company changes the world or reinvents an industry without being bold. It must be balanced; not by timidity, but by doing the right thing even when no one is looking.
  • We are One Recursion: We operate with a 'company first, team second' mentality. Our success comes from working as one interdisciplinary team.

Recursion spends time and energy connecting every aspect of work to these values. They aren’t static, but regularly discussed and questioned because we make decisions rooted in those values in our day-to-day work. You can read more about our values and how we live them every day here.
