Integrations Engineer

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.

We're open to considering mid, senior and staff-level candidates, which may result in an adjustment to the scope and compensation

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. You'll 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. This involves deep integration with existing telecom networks and a high degree of cross-organizational collaboration to push projects forward and develop innovative products.
• Maintain the reliability of our systems, building for observability and participating in incident response. This includes coordinating advanced retry logic and contributing to support rotations for intricate external system interactions.

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.
• 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 — it helps us build deeper relationships with partners, navigate regional nuances, and deliver more seamless experiences across the markets we serve.
• Grit and Technical Ingenuity: You possess the perseverance to design robust solutions for complex, evolving external systems, skillfully navigating dynamic behaviors through systematic debugging and experimentation.
• Strategic Collaborator: You adeptly navigate large organizational structures, collaborating effectively with diverse teams and stakeholders, and understanding the intricate business context behind commercial offerings.
• Eager to Master New Domains: You have a strong desire to learn and quickly grasp new domains, including intricate regulatory flows and industry specifics, to build stable and compliant solutions.
