About the role
We are looking for a Senior Backend Engineer to join Vio's Meta Integrations team and help us in our expansion to different meta channels, in the identification and delivery of the best deals to different Metasearch channels, and ensure that our customers will get the best deal. The MINT (Metasearch Integration) team builds, maintains, and improves Vio's technical integrations with metasearch partners — ensuring we can participate in these channels reliably and at scale.
We are working with a modern stack consisting of Go, AWS (ElastiCache, StepFunctions, ECS, S3, etc.), Redis, Snowflake, Terraform, and more. We process large amounts of data daily and integrate with many suppliers. Meta Integrations products are a core part of Vio's platform allowing us to offer the best possible comparison and offer to every traveler, worldwide. Hence, anything that you will develop and ship on production will have an immediate effect on our users and on our business performance. We work in a flexible, results-oriented, and customer-centric team structure, focusing on shipping value in a collaborative fashion, with hopefully just the right amount of bureaucracy.
What you will do
Build and evolve metasearch integrations — deliver new features and improvements for partner-facing technical integrations, ensuring correctness and robustness as partner requirements change
Own and improve Meta Integrations’ core production systems end-to-end — take ownership of critical services, including on-call readiness and driving reliability improvements over time
Drive system design and technical decision-making — write design docs, review designs with peers, make pragmatic architecture trade-offs, and break down ambiguous problems into iterative delivery plans
Continuously improve performance, reliability, and cost efficiency — identify bottlenecks in throughput/latency, infra spend, and caching strategy, then ship measurable improvements
Operate in a data-informed way — leverage data engineering and analysis to validate changes, debug production behavior, and measure impact (partner performance, system health, quality metrics)
Raise the bar for the team — mentor engineers, improve engineering practices, reduce knowledge silos, participate in hiring, and influence technical direction across team boundaries
Who you are
You have 5+ years of experience designing, shipping, and operating high-scale back-end services in production, including incident management and postmortems
You are proficient with Golang and you have experience with at least two programming languages such as Go, Rust, Python, Java or Scala, or Ruby.
You have strong distributed systems fundamentals and a track record of finding bottlenecks and improving performance, reliability, and code quality
You can write design docs and defend architecture trade-offs clearly with engineers and product partners
You are data-literate — comfortable with data pipelines and using data to debug production behavior and validate impact
You thrive under ambiguity — able to take underspecified problems, break them down, and ship iterratively while keeping quality high
You've worked in cross-functional product environments (with PM, analytics, etc.) in agile setups, not only "ticket-taking"
You are a self-starter with end-to-end ownership mentality, intellectual curiosity, and a pragmatic team-first attitude
You communicate clearly and concisely, especially in design discussions and stakeholder alignment
Nice to have: Experience with external partner/API integrations, R&D/experimentation, open-source contributions, and mentoring/leading through influence
