Senior Software Engineer, Integrations

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 150 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

We’re looking for a Senior Software Engineer, Integrations who thrives at the intersection of engineering and impact. You’re a backend expert who doesn’t just write code — you connect systems, unblock teams, and turn complexity into seamless solutions. For you, code is a means to an end: delivering business value, creating elegant integrations, and helping products work smarter together. If you love solving tough challenges, collaborating across functions, and building the glue that makes everything click, this role is for you.

Salary range

Europe: €85,000 - €125,000. United Kingdom: £105,000 - £120,000

What You Will Do

• Own complex problems end-to-end, from designing and building robust, scalable solutions to ensuring a high standard of quality across our engineering practice.
• Integrate with and maintain a wide range of APIs and external systems, primarily in Ruby.
• Architect solutions that abstract diverse external behaviours and manage the complexities of asynchronous flows, distributed state synchronisation, and dynamic data validation.
• Tackle the unique challenge of building a new telco operating system, involving deep integration with existing telecom networks and a high degree of cross-organisational collaboration.
• Maintain the reliability of our systems, building for observability and participating in incident response.

What We Are Looking For

• You have experience designing APIs and building backend services.
• You enjoy thinking about systems, and you care about the quality of the software you produce.
• Strong English communication skills: You can clearly explain complex ideas, collaborate across global teams, and thrive in a company where English is the common language.
• European Language Skills (a Plus): Proficiency in one or more European languages is a bonus.
• Grit and Technical Ingenuity: You possess the perseverance to design robust solutions for complex, evolving external systems.
• Strategic Collaborator: You adeptly navigate large organisational structures, collaborating effectively with diverse teams and stakeholders.
• Eager to Master New Domains: You have a strong desire to learn and quickly grasp new domains, including intricate regulatory flows and industry specifics.

Work At Gigs

At Gigs, we value in-person collaboration. We believe the best ideas, decisions, and relationships are built when teams spend meaningful time together, and our culture is designed around that belief. We support flexibility where it makes sense. Some focused work can be done remotely, and not every role or week looks the same. You should expect regular time in one of our hubs, as well as occasional travel for team workshops, customer meetings, and Gigs Republic, our bi-annual company off-site.

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 of course, a free phone and international data plan.
