Senior Backend Engineer, US Activation & Retention

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, bringing together early-stage engineers, product builders, and business athletes from companies like Stripe, Airbnb, and Shopify. 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

We are building in a highly complex space and tackling a massive problem. We want people who lean in when things get hard.

• 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

The US is a key market for Gigs, and US Activation & Retention (USAR) is the team that helps it grow. We work directly with our US partners, some of the biggest brands in the market, to build what they need. The features you build have a direct impact on how fast Gigs grows.

This is not a role where you stay in one corner of the codebase. To get a feature live for our US partners, the team works across many domains of our platform. If you want broad ownership, direct contact with partners, and a clear line from your work to the company’s growth, this team is for you. Once here, you will: 

• Own complex problems end-to-end, working with our talented team to design and build robust, scalable solutions.


• Develop innovative products that empower our customers to bring world-class connectivity services to their users with ease.


• Uphold our high engineering standards, improving tooling and processes where necessary.


• Design, build and maintain best-in-class APIs and services. Our primary codebase is a Ruby on Rails monolith, complemented by a number of services written in Go, Elixir and TypeScript. You don’t need to have deep expertise in all of our languages; we will give you plenty of room to learn and grow with your team.


• Keep our platform reliable. You’ll build services with observability in mind from the start and take part in incident response.

Salary range for Senior Engineer: $220,000 - $275,000 (base salary) + equity

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.


• You use AI as a core part of how you work, not an occasional shortcut. That means prompting agents with context and intent, reviewing what they produce critically, and knowing when to push back. You can explain the code an agent wrote, catch when it oversteps the ask, and form your own opinion on whether the output is actually good. You're curious about how the tooling is evolving and actively working to get better at it.


• You enjoy building products from scratch. You care about finding the right solution to customer needs, and you’re comfortable taking ownership and delivering.


• You love learning technologies as you go. You always want to find the right tool for the job, and don't only follow what you already know.


• You care about more than just engineering. You need to see the business impacts of everything you do. You know how to make speed/quality trade-offs.
