Senior Software Engineer
Senior Software Engineer
London – Hybrid
We’re working with a growing, international technology business at a pivotal stage of its scale-up journey. With a high-performing team of around 40 people and ambitious growth plans, the company is now seeking a Senior Software Engineer (Platform) to strengthen its infrastructure foundations and support the next phase of scale.
Reporting to the VP of Engineering, this is a senior technical leadership role focused on platform reliability, scalability, and operational excellence. While not a people management position, it carries significant influence across engineering and plays a central role in how systems are designed, delivered, and operated.
What you’ll be doing
Platform leadership & reliability
- Owning the reliability, scalability, and health of production systems
- Leading improvements across CI/CD, infrastructure-as-code, and cloud environments
- Driving observability, incident response, and operational best practice
- Ensuring platform foundations support continued growth and delivery speed
Technical direction & architecture
- Partnering with the VP of Engineering on key architectural decisions
- Guiding platform and infrastructure patterns across the engineering function
- Helping the team make pragmatic trade-offs between speed, resilience, and complexity
- Embedding best practice in cloud infrastructure and system design
Operational excellence & delivery
- Contributing hands-on through code and end-to-end problem ownership
- Enhancing developer experience and internal tooling
- Supporting scaling and capacity planning across AWS environments
- Enabling product engineers to ship quickly and safely
Collaboration & influence
- Mentoring engineers and raising technical standards
- Leading through code reviews and technical discussions
- Acting as a bridge between platform and product engineering
What we’re looking for
- 5+ years of software engineering experience, including time in DevOps, SRE, or platform roles
- Strong experience with AWS and infrastructure-as-code (e.g. Terraform, CDK)
- Deep understanding of CI/CD, observability, and production reliability
- Experience designing and scaling distributed systems
- Broad technical depth across infrastructure and application layers
- Influence built on credibility and trust rather than authority
- Clear communication and pragmatic decision-making
- Hands-on, improvement-focused, and team-oriented
What you’ll get
- A senior technical leadership role in a business entering its next growth phase
- High visibility across engineering and executive leadership
- Real influence over platform architecture and system reliability
