About the Role

Job Title: Junior/Mid Software Engineer
Location: London
Employment Type: Full-Time
Department: Software
Work Model: Hybrid

As a Junior/Mid level Software Engineer (depending on experience), you’ll be contributing across all areas of our full-stack product based in the Cloud and our IoT devices that interface with Mytos hardware to manufacture cells. 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

• Collaborate closely with other engineers to 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 learn about 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.
• Learn and contribute to our testing methods to help us deliver quality software at speed.
• Learn and contribute to architecture and infrastructure, system performance, and interesting distributed system challenges.
• Write code that you can immediately see the real-world impact: testing on our prototype machines in our own lab.
• Up-skill in domains outside software engineering, from donning a lab coat and being trained on the nuances of stem cells to the basics of fluid mechanics.
• Be given a lot of autonomy, responsibility, and ownership of product problems and the technical solutions you design and deliver to address customer needs.

What We're Looking For

• Early in your software career and want to join an environment that gives you the chance to grow quickly.
• Demonstrated technical promise in your studies or work.
• Desire to work on difficult technical challenges in a field that will define the biggest scientific advancement this century.
• Self-starter attitude with a drive for producing quality work.
• Care and compassion for customers and colleagues.
• 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).
• Experience working with databases (PostgreSQL and Prisma or similar ORM experience ideal).

Our Technologies

• Frontend (Netlify): React, TypeScript, GraphQL, Storybook
• Backend (AWS & Heroku): NodeJS, TypeScript, GraphQL, MQTT, PostgreSQL, Python, Pulumi IaC
• Physical Device (on-premise): NodeJS, TypeScript, FastAPI, Python, MQTT
• Firmware: C++, GTest, GMock, Bazel, Platformio

Nice-to-Haves

• Understanding of distributed systems concepts.
• Experience with Python for data processing or image analysis.
• Background or interest in biology, lab automation, or scientific instrumentation.
• Experience with regulated environments (GMP, HIPAA, etc.).
• Experience with UI/product design processes and tools (wireframes, mockups, looks-like prototypes, etc.).

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.
• 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).
• Workspace with office, workshop, and wet lab facilities in the Imperial College Innovation hub, White City.
• Strong in-person culture with team lunches covered daily when in office.
• Flexible working with core hours (10am to 4pm) to support team collaboration.
• Hybrid working (typically 2-3 days on-site per week) that respects where you do your best work while maintaining overall team efficiency.
• Competitive pension scheme with tax-efficient salary sacrifice option.

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. No GMP experience? No problem! We want someone who is motivated to deliver an innovative product into a regulated space with creative, efficient solutions.

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!
