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. Just as Stripe lets any business add a payment button in seconds, Gigs empowers platforms to weave in connectivity—bridging the traditional world of telecom with modern tech. From fintechs launching mobile services to HR platforms offering work phone plans, we automate provisioning and remove telecom complexity.

Our team of around 100 people across the US and Europe, backed by nearly $100 million in funding from Ribbit Capital, Google, and Y Combinator. As one of the fastest-growing tech companies, we’re tackling deep technical and regulatory challenges to make connectivity truly seamless. If you’re driven by curiosity, creativity, and the chance to shape the future of telecom, we’d love to hear from you.

Things We Care About

• Speed. We move and we ship. We set bold deadlines and treat every week like it matters.
• Ownership. If you see something broken, fix it. We don't wait for permission.
• Customer Obsession. Our customers' product is our product.
• Ambiguity. We're building frontier technology in a complex domain. You'll need sound judgement and good instincts to make decisions without complete information.
• First principles. We don't ask how things have been done before. We ask why they were done that way at all.

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.

This is a role for someone who cares deeply about the craft of platform engineering — who gets energy from making other engineers more productive, who thinks in systems, and who isn't satisfied until the solution is both robust and elegant. You'll be joining a small, high-impact team where your work will directly shape how Gigs scales over the next few years.

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 e.g. 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.
