Senior Platform Security Engineer

Job Description

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 cure diseases like Parkinson’s and -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. You can learn more about your potential Mytos teammates here: Team

Mytos is backed by Y Combinator, the most successful startup program in the world which produced companies such as AirBnb, Dropbox, and Ginkgo Bioworks.

The Role

As a Senior Software Engineer focused on Platform & Security, you'll take a leading role in evolving and maturing our security and compliance posture while building robust infrastructure for our cell manufacturing platform. Mytos is already SOC 2 Type 2 audited, but as our our customers move from research into production of cell therapies, they need our technology to be suitable for GMP environments.

In this role, you'll be responsible for designing and implementing the infrastructure, processes, and features needed to support cell therapy manufacturing in regulated environments. You'll create elegant solutions that are secure, compliant, and reliable without sacrificing the speed and flexibility that make Mytos successful — enabling scientists to develop breakthrough therapies with confidence.

What you'll do

• Build and maintain secure, scalable infrastructure for our distributed system, which spans cloud services and on-premise hardware
• Represent Mytos to customers' executive, security, and quality teams, effectively communicating our approach to security, compliance and risk management
• Own Mytos' information security program (e.g., SOC 2, ISO 27001) and work cross-discipline to bring the business and product into GMP environments
• Develop automated testing and validation strategies that build quality into our development process rather than bolting it on afterward
• Streamline our deployment processes enabling both rapid development and stable validated environments for manufacturing customers
• Implement and improve security practices, including code scanning, access controls, and audit logging, ensuring compliance with industry standards
• Build core product features like electronic signatures, audit logging, and data traceability for customers based on your own user research
• Collaborate with cross-functional teams to build a Quality Management System that aligns with regulatory requirements whilst preserving our engineering culture
• Develop core architecture improvements for system reliability, database performance, API security, and distributed system design
• Mentor the team on security and quality best practices, helping to build a culture where compliance is a natural outcome of good engineering

Must-haves

• Experience with cloud infrastructure and DevOps practices (AWS )
• Experience implementing and maintaining security controls and compliance frameworks
• Proficiency with infrastructure-as-code and GitOps methodologies
• Strong fundamentals in API design, databases, networks, and distributed systems
• Experience with CI/CD pipelines and automated testing
• TypeScript and Node.js proficiency in production environments
• Understanding of security principles and experience implementing them in production systems
• Ability to communicate complex technical concepts to non-technical stakeholders and interface directly with vendors and customers

At least one of these areas

• Compliance framework experience: Implementation or maintenance of ISO 27001, ISO 9001, SOC 2, or similar frameworks
• Regulated industry background: Experience in healthcare, finance, or other regulated domains that required balancing innovation with compliance
• Lifecycle management expertise: Experience designing systems that maintain both rapidly changing and stable validated components
• Quality systems implementation: Experience building automated quality checks, validation frameworks, or similar systems

Nice-to-haves

• Knowledge of relevant standards and compliance frameworks (e.g. ISO 27001, SOC 2, ISO 9001, GAMP 5, FDA 21 CFR Part 11, ALCOA+, BS 10008)
• Experience with regulated environments (GMP, HIPAA, etc.)
• Understanding of hardware-software integration
• Experience with containerisation and orchestration (Docker, Kubernetes)
• Experience with Python for tooling or data processing
• Background in manufacturing or laboratory automation
• Experience with database performance optimisation and data integrity enforcement

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. 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!
