Senior Software Development Engineer (6-month contract)

As a Senior Software Engineer, you will lead the design and development of core systems that drive lifecycle engagement of the company, personalized marketing automation (Martech), and strategic partnership integrations. You'll own large-scale, high-concurrency systems end-to-end—from real-time event tracking and reward engines to partner sync pipelines—operating with autonomy and shaping the technical architecture of our ecosystem. This role is ideal for engineers who excel at solving complex distributed data problems, building scalable backend services, and mentoring others toward engineering excellence.

About the Team Our team sits at the intersection of user retention, growth, and ecosystem monetization. We build and scale the platforms that power our automated engagement campaigns and seamless integrations with external partners and brands. Whether we are processing high-throughput event streams for real-time personalization, orchestrating complex cross-channel martech workflows, or managing high-availability transactional data stores, our engineering focus is on resilience, speed, and clean architecture. If you are passionate about building systems that directly impact millions of users' retention and engagement journeys, we'd love to talk.
