Senior Platform Engineer in London

About Gigs
At Gigs, we're building the operating system for mobile services—a platform that lets tech companies embed global connectivity into their products effortlessly.

The Role
As a Senior Platform Engineer at Gigs, you'll work at the foundation of everything we build. You'll design, build, and operate the infrastructure and developer tooling that powers our connectivity and payments platform—enabling product teams to ship faster, more reliably, and at scale. Our Foundation team owns the systems that every engineer at Gigs depends on: CI/CD pipelines, cloud infrastructure, observability, deployment tooling, and the shared platform services that keep our product running. You'll take ownership of complex infrastructure challenges end-to-end and drive them to production with a high bar for reliability and developer experience.

What You Will Do
• Own and improve Gigs' cloud infrastructure, ensuring our platform is reliable, scalable, and cost‑efficient as we grow.
• Design and build internal developer tooling and platform services that accelerate how product teams ship—from CI/CD pipelines to deployment workflows to local development environments.
• Drive improvements to our observability stack, making it easy for every engineer to understand system behavior, debug issues, and respond to incidents with confidence.
• Take complex infrastructure problems end‑to‑end: scoping, designing, implementing, and operating solutions in production.
• Collaborate closely with product engineering teams to understand their pain points and build platform capabilities that unblock them.
• Contribute to our infrastructure‑as‑code practices, ensuring our cloud environments are reproducible, auditable, and version‑controlled.
• Participate in on‑call rotations, incident response, and post‑mortems—and use what you learn to make our systems more resilient.
• Raise the bar for platform engineering quality through code reviews, documentation, and advocating for best practices across the team.

What We Are Looking For
• You have 5+ years of professional software engineering experience, with meaningful time spent on infrastructure, platform, or DevOps/SRE work in a production environment.
• You have experience designing and building platform layers such as centralised authentication, observability, routing logic, or API versioning which other product teams integrate against or build on top of.
• You have hands‑on experience with cloud platforms (GCP preferred) and infrastructure‑as‑code tools like Terraform.
• You understand networking, compute, and storage at a level that lets you make good trade‑offs.
• You have experience building and maintaining CI/CD pipelines and deployment systems.
• You care about developer experience and know that a great platform is one that engineers actually want to use.
• You think in systems. You can reason about distributed architectures, understand failure modes, and design for reliability and observability from the start.
• You enjoy building products from the infrastructure up.
• You care about finding the right solution to internal customer needs, and you're comfortable taking ownership and delivering.
• You communicate clearly and collaborate well. You can explain infrastructure decisions to product engineers, write useful documentation, and contribute to technical discussions with confidence.
• You care about more than just engineering—you want to see the business impact of everything you do, and you know how to make pragmatic speed/quality trade‑offs.
• You have a growth mindset when it comes to tooling and practices. You stay curious about how the industry is evolving—including AI‑assisted development—and you're thoughtful about adopting what makes you and your team more effective.

Bonus Points If
• You have experience with our stack: GCP (cloud run), Docker, Terraform, Ruby on Rails, Go, PostgreSQL, Kafka, PubSub.
• You have worked in fintech, payments, telecom, or other regulated industries where reliability and compliance matter.
• You have experience building developer‑facing platforms or internal tooling at a high‑growth startup (Series B–D).
• You have contributed to open‑source infrastructure tooling or have a track record of improving developer productivity at scale.
• You use AI tooling as part of your engineering workflow and have developed a practical sense for where it adds value and where it doesn't—for example, using it for infrastructure scaffolding, debugging, exploring unfamiliar APIs, or drafting documentation while knowing when to rely on your own judgment.

What We Offer
At Gigs, we believe in rewarding excellence. We offer competitive compensation and stock options because we see you as a true partner in our growth. We also provide stipends for your home office or work setup, a budget for learning and development to fuel your career, and a free phone and international data plan.
