Senior Software Engineer, Backend About Gigs: We’re building the operating system for mobile services—a platform that lets tech companies embed global connectivity into their products effortlessly. Our team of around 100 people across the US and Europe is backed by nearly $100 million in funding from Ribbit Capital, Google, and Y Combinator. We’re tackling deep technical and regulatory challenges to make connectivity truly seamless. 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. Code is a means to an end: delivering business value, creating elegant integrations, and helping products work smarter together. 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 behaviors and manage the complexities of asynchronous flows, distributed state synchronization, and dynamic data validation. Tackle the unique challenge of building a new telco operating system—deep integration with existing telecom networks and cross‑organizational collaboration to push projects forward and develop innovative products. Maintain system reliability by building for observability and participating in incident response, including coordinating advanced retry logic and supporting rotations for intricate external system interactions. What We Are Looking For Experience designing APIs and building backend services. Enjoy thinking about systems and caring about software quality. Perseverance to design robust solutions for complex, evolving external systems, navigating dynamic behaviors through systematic debugging and experimentation. Strategic collaboration across large organizational structures, working effectively with diverse teams and stakeholders, and understanding the business context of commercial offerings. Strong desire to learn and quickly grasp new domains, including intricate regulatory flows and industry specifics, to build stable and compliant solutions. Before You Apply… We expect urgency and ownership. This role may not be a fit if you need a lot of structure, prefer specialized narrow roles, are uncomfortable making decisions with imperfect data, or want a “big company” setup. If you’re excited to build from zero, work with passion, and leave a mark on something that matters, we’d love to meet you. Work at Gigs We know different work styles thrive in different environments. Some work best remotely, others need in‑person collaboration. We’re remote‑friendly by design and offer hubs for those who need the energy and focus that only in‑person collaboration can bring. Gigs Pads: Our hubs in San Francisco, London, Amsterdam, and Berlin are vibrant spots where Gigsters connect, collaborate, and create together. Gigs Republic: Twice a year, our entire company comes together to strengthen bonds, align on big ideas, and share experiences that fuel our culture and ignite growth. What We Offer We reward excellence with competitive compensation and stock options. We provide stipends for home office or work setup, a learning and development budget, a free phone, and an international data plan. #J-18808-Ljbffr
