Senior Software Engineer - Flight Data Systems

AirHelp is a global travel tech company on a mission to make every journey smoother. We built our name helping millions of travellers claim the flight compensation they're owed - and that's now the foundation of a broader platform of travel protection and convenience products spanning the entire journey. We're hiring a Senior Software Engineer to build our Flight Data Systems - the real-time backbone that ingests, normalizes, and serves flight status, schedules, and disruption signals from a wide range of external sources. This data powers all our services that support millions of travellers around the world. This is a hands-on senior role with strong ownership. You'll work primarily in Go, designing high-throughput, fault-tolerant services, and making technical decisions for the domain. If you're motivated by hard data and systems problems, shipping fast, and working in a high-trust, low-politics environment where your output actually matters, this is for you. This is a hybrid job opportunity in Kraków, Warsaw or Gdańsk. Salary: • If you join us as a full-time employee: 18.000 - 23.000 PLN gross/month • If you join us as a contractor (for specific projects): 19.000 - 26.000 PLN net + VAT/month on B2B contract

What you can expect from us:• Ownership of a core domain - Flight Data - where your architectural decisions directly impact the travel experience for millions of users and the reliability of the whole platform. • Culture that promotes good engineering practices, high-quality code, and continuous improvement. • Daily deployments to production, ensuring fast impact and iterative development. • Access to a modern tech stack and a variety of functional areas, including: • Backend: Go • Databases: PostgreSQL, Snowflake • Infrastructure: AWS, Docker, Kubernetes, Terraform • Monitoring: ELK/Grafana, Sentry, GitHub Actions CI/CD • Testing: Bruno (API), Playwright (E2E), k6 (performance)

What you'll do:• Design, build, and scale Go services that ingest flight data from many heterogeneous external providers, reconcile conflicting signals, and serve a reliable, normalized view to the rest of the platform. • Own performance, correctness, and uptime of Flight Data Systems. • Lead initiatives to modernize and optimize critical parts of the platform, and influence architectural decisions across services and team boundaries. • Ship production-ready code daily, with strong testing discipline. • Improve internal developer velocity by contributing to shared tooling, CI/CD pipelines, and infrastructure as code. • Mentor peers and raise engineering standards through code reviews, design discussions, testing discipline, and documentation. • Partner with product owners and stakeholders to frame problems early, identify risk areas, and turn ambiguous data requirements into robust, maintainable systems.
