Senior Software Engineer (London Area)

About Mytos

You rarely get the chance to change an entire industry. But that’s the position we find ourselves in. Join us, and you’ll unleash scientists, accelerate their research and help get cures to patients sooner. We’ve developed machines to fully automate human cell production - the most manual process in Biotech. Cells are used to discover and develop new drugs, and now they’re being used to cure diseases like Parkinson’s and age-related blindness. Mytos will impact cure development across the board.

We’re live in multibillion dollar biotechs on both coasts of the US, and raised $19m to expand into the market faster, and accelerate our development! Next year, neurons grown on our machines will be going into Parkinson patient brains. We’ve assembled a world-class team to take on this challenge, with ex-Dyson engineers and Nature-published scientists working hand-in-hand.

The Role

As a Senior Software Engineer focused on full-stack product development, you’ll build the critical interfaces and systems that enable scientists to work with our cell manufacturing platform. You’ll create intuitive, reliable software that abstracts away complexity while giving users powerful tools to customise and monitor cell growth protocols.

Any experience with distributed systems will translate well to our environment, where you’ll find familiar concepts like asynchronous communication and managing state consistency across components — with the added excitement of components including physical hardware! Your work will directly impact how quickly and effectively new therapies and research tools can be developed, ultimately helping patients worldwide.

What you’ll do

• Work directly with customers to translate their scientific workflows into reliable, flexible and simple software solutions
• Own and deliver end-to-end product functionality spanning experiment scheduling, automated image analysis, and remote operation of our devices
• Develop and improve our frontend applications using TypeScript, React, and GraphQL to create intuitive interfaces for complex biological workflows
• Build backend services that communicate with our hardware systems and ensure data integrity throughout the cell manufacturing process
• Collaborate across disciplines with hardware engineers, biologists, and commercial teams to build reliable and effective systems in record time
• Leverage tooling and automated testing to deliver quality software at speed
• Contribute to the core architecture of our systems, improving database performance, data integrity, API design, and distributed system reliability

Must-have

• Strong experience with full-stack web development using TypeScript or other typed languages
• Experience with modern frontend frameworks (React preferred)
• Experience with backend development and API design (Node.js preferred)
• Understanding of distributed systems concepts
• Experience working with databases (PostgreSQL and Prisma or similar ORM experience ideal)
• Experience working with complex data and creating intuitive interfaces to manage it
• Ability to work effectively in cross-functional teams
• Strong communication skills and customer empathy

At least one of these areas

• Product thinking and design mentality
• Deep distributed systems expertise
• Systems control understanding

Nice-to-have

• Experience with Python for data processing or image analysis
• Background or interest in biology, lab automation, or scientific instrumentation
• Experience working with or building distributed systems
• Experience with regulated environments (GMP, HIPAA, etc.)
• Experience with UI/product design processes and tools

Why You’ll Love Working Here

• Impact: Your work will directly enable the production of cell therapies that can transform patients' lives.
• Growth: We’re solving complex problems at the intersection of software, hardware, and biology—you’ll constantly learn and develop new skills.
• Autonomy: You’ll have the freedom to shape our approach to GMP readiness, with support from a talented cross-disciplinary team.
• Team: Work with the best engineers and scientists in a collaborative environment where diverse perspectives drive innovation.

Salary and Benefits

• Competitive salary with stock options
• Lunch covered daily in-office with team
• Collaborative team environment with very high potential to learn new skills
• 32 days holiday (bank holidays, end-of-year closure, and 21 days discretionary PTO)
• Pension
• Awesome colleagues and an office in the Imperial College Innovation hub in White City, where you’ll be based

We’re building a team that enjoys moving fast, strives for continuous improvement through learning from mistakes, and is passionate about work that contributes to solving real world problems. If you’re excited about solving interesting problems at the intersection of software, hardware, and biology while helping us prepare for the next phase of our growth, we want to hear from you!
