Design and scale high-throughput Go services to ingest and normalize flight data from various external providers. Lead architectural decisions for the Flight Data Systems domain while mentoring peers and improving developer velocity.
Requirements
Requires 5+ years of software engineering experience with deep expertise in Go and building data-intensive backend systems. Must be proficient with AWS, containerization, and relational databases, with a strong ownership mindset.
Full job description
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:
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.
What sets you apart:
5+ years of hands-on software engineering experience, with significant depth in Go building production backend services.
Proven experience designing and operating high-throughput, data-intensive or event-driven systems - pipelines, streaming/ingestion, queues, and real-time APIs.
Strong grasp of concurrency, reliability, and performance trade-offs.
Solid understanding of relational databases (PostgreSQL preferred) and data modeling for evolving real-world data.
Comfort working across the entire SDLC: from problem framing to deploying and monitoring production.
Experience in cloud-based environments (especially AWS) and with containerized workloads (Docker, Kubernetes).
Ownership mindset: you don't wait for tickets - you find problems and solve them.
Clear communication, constructive feedback, and a focus on outcomes.
Strong command of English (both spoken and written).
Bonus points for:
Experience integrating third-party data feeds, dealing with rate limits, schema drift, and unreliable upstreams.
Familiarity with the aviation/travel domain.
Experience with observability and SLO-driven operations for critical services.
Why AirHelp:
Fast Impact: We deploy daily. Your work goes live and makes a difference fast.
Culture of Autonomy: High trust, zero politics. We hire builders, not order takers.
Growth Investment: Dedicated learning days, personal development plans, internal workshops, mentorship, and language classes.
Perks: Private healthcare, wellness budget, travel stipend, gym/transport subsidy, AirHelp services for free, and more.
