At Drivvn, we're on a mission to transform how people buy and lease vehicles and we'd love for you to be part of it. As proud winners of the Culture
100 Award, we're recognised not just for our innovation, but for putting our people at the heart of everything we do. Since launching in 2020 as part of the TCC Group, we have been working with major automotive brands like Stellantis, Ford, Volvo, and Volkswagen to deliver seamless digital retail experiences. More recently, we've expanded into vehicle leasing, collaborating with forward-thinking partners such as MHC and Leasys.

Our platform supports the entire automotive sales and leasing journey, from vehicle configuration to financing, with real-time integration and omnichannel capabilities that put the customer in control. Our platform handles millions of real-time pricing calculations and inventory updates, integrating deeply with OEM systems, DMS platforms, and finance providers. We're currently focused on the European market, but we're thinking big and have exciting plans for global expansion.

In FY25, we generated over £8 million in revenue and we know that our success is all thanks to the brilliant people who make up our team.

As a Site Reliability Engineer, you will join our platform engineering team with a clear focus on application performance and production reliability. You will live in our observability tooling, Datadog in particular, spotting slow endpoints, error spikes and resource bottlenecks across our multi-tenant automotive SaaS platform, diagnosing them down to the code, and working with the owning teams to get fixes prioritised and delivered.

You’ll also have the opportunity to contribute, alongside our Senior Platform Engineers, to how we use AI-driven automation, Model Context Protocol (MCP) integrations and agentic workflows across the platform.

• Own day-to-day use of Datadog across our platform, using APM, distributed tracing, logs and infrastructure metrics to find and prioritise performance issues across storefronts

• Diagnose performance problems to root cause in our PHP/Symfony and Node.js services, including slow database queries, N+1 patterns, cache misses, PHP-FPM saturation and memory pressure

• Build and maintain Datadog dashboards, monitors and SLOs as code using Terraform, so every service has meaningful, version-controlled signals

• Run a regular performance review with Engineering Managers, tracking the top issues, trends and the impact of fixes over time

• Turn findings into clear, evidence-backed tickets for the owning team, with traces, metrics and a proposed fix, and follow them through to delivery

• Maintain the performance and reliability backlog in Linear, tracking remediation progress with Engineering Managers and escalating unresolved reliability risks

• Raise pull requests directly for well-scoped fixes where it is quicker than handing off

• Respond to alerts and incidents, using runbooks to restore service efficiently, and contribute to post-incident reviews with clear follow-up actions

• Once you’re up to speed on the platform, join our on-call rota to support production incidents

• Work with fellow platform engineers on our Azure and AKS infrastructure, managed with Terraform and deployed via Git Ops (ArgoCD)

• Tune alerting to reduce noise and make sure the right team is paged for the right problem

• Write automation (Python, Bash, or similar) to reduce manual investigation and repetitive operational work

• Apply a security-conscious mindset to everything you build, including secrets management and least-privilege access for observability tooling
