Job description
Join a high-performing Core Engineering team where collaboration, trust, and technical excellence are at the heart of everything we do. Our team is a diverse group of software and platform engineers who thrive on solving complex challenges and building the foundational systems that power the entire engineering organization. We value ownership, reliability, and a willingness to support each other-especially when it matters most. You'll work alongside talented peers who are passionate about automation, reliability, and continuous improvement, in an environment where your expertise and initiative are recognized and celebrated. If you're driven by impact, eager to mentor others, and excited to shape the future of our platform, you'll find a supportive and inspiring home here. This role is a senior technical leadership position in platform engineering with a strong Site Reliability Engineering (SRE) focus, responsible for building, automating, and operating foundational infrastructure and services that maximize engineering productivity, reliability, and scalability.
What You'll Be Doing
- Architect, implement, and manage cloud-native infrastructure (Kubernetes, Terraform, Terragrunt, Docker, Azure) to support scalable and reliable platforms.
- Champion SRE principles: drive service reliability, availability, and performance through automation, monitoring, and incident management.
- Lead platform automation, CI/CD, and infrastructure-as-code initiatives to improve deployment velocity and system consistency.
- Own observability, monitoring, and alerting using Datadog and related tools, ensuring actionable insights and rapid incident response.
- Collaborate with software engineers to ensure robust integration between application and platform layers, and to improve developer experience (DevX).
- Provide expert support for critical incidents and production issues, demonstrating high ownership and urgency (including out-of-hours support when required).
- Mentor and guide engineers in platform, SRE, and DevOps best practices, fostering a culture of reliability and continuous improvement.
- Identify and address gaps in tooling, automation, and platform reliability to proactively improve engineering outcomes.
Requirements
- Deep expertise in platform engineering with a strong grounding in SRE principles (SLIs/SLOs, incident response, automation, reliability).
- Proven experience with cloud infrastructure (preferably Azure), container orchestration, infrastructure-as-code (Terraform and Terragrunt), and automation.
- Demonstrated ability to resolve complex reliability and infrastructure challenges independently and proactively.
- High sense of ownership, reliability, and willingness to go above and beyond for the team and organization.
- Excellent communication and collaboration skills, able to work effectively across engineering and product teams.
- Trusted advisor and role model for platform and SRE excellence, setting standards for reliability, automation, and operational maturity.
Benefits & conditions
- Competitive base salary
- Equity ownership opportunities
- Comprehensive health benefits packages (medical, dental, non-contributory pension scheme)
- Robust leave policies (PTO, parental leave, VTO)
- Flexible work environment with two days working from the London Office
- Mission-driven, collaborative, and inclusive culture
