About the Role

Job Title: Senior Software Engineer (Platform & Security)
Location: London
Employment Type: Full-Time
Department: Software

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 customers move from research into production of cell therapies, they need our technology to be suitable for GMP environments.

Responsibilities

• Design and implement the infrastructure, processes, and features needed to support cell therapy manufacturing in regulated environments.
• 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.
• 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.
• Build core product features like electronic signatures, audit logging, and data traceability based on user research.
• Collaborate with cross-functional teams to build a Quality Management System that aligns with regulatory requirements.
• Develop core architecture improvements for system reliability, database performance, API security, and distributed system design.
• Mentor the team on security and quality best practices.

Must-haves

• Experience with cloud infrastructure and DevOps practices (AWS preferred).
• 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.

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.
• Lifecycle management expertise: Experience designing systems that maintain both rapidly changing and stable validated components.
• Quality systems implementation: Experience building automated quality checks or validation frameworks.

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).
• Experience with regulated environments (GMP, HIPAA, etc.).
• Understanding of hardware-software integration.
• Experience with containerization and orchestration (Docker, Kubernetes).
• Experience with Python for tooling or data processing.
• Background in manufacturing or laboratory automation.
• Experience with database performance optimization 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: Solve complex problems at the intersection of software, hardware, and biology.
• Autonomy: 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.

Salary and Benefits

• Competitive salary with stock options.
• Collaborative team environment with 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.

We're building a team that enjoys moving fast, strives for continuous improvement, and is passionate about 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!
