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
