Senior Software Engineer - Flights

Are you a Software Engineer who thrives on real ownership?

At Perk, we know that we feel most fulfilled when we can own the problem and the solution. This means taking responsibility for the entire lifecycle of a feature, from being part in understanding what our customers' pains are with our product team, design documents, coding to deployment, and measuring impact. You will see how your technical decisions move the needle for our customers daily.

We prioritize autonomy and pragmatism, giving you the space to solve complex problems without unnecessary friction. Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a global platform.

Flights is one of Perk's fastest-growing engineering areas — expanding from one team to four since 2025, with more growth ahead.

The domain is genuinely complex. A single flight booking involves far more steps, suppliers, and failure modes than most people realise. Our job is to hide that complexity and deliver a seamless customer experience. We’re not there yet — and that's the opportunity.

You’ll be working across mission-driven teams tackling core platform reliability, self-serve post-booking, booking error recovery, and airline inventory scaling. Each team is cross-functional, so you’ll work alongside product, design, and operations — not just engineers.

We know where we want to get to. We don’t have all the answers for how to get there — and we want the people we hire to help us figure that out.

At Perk, we believe the best work happens when great people come together in small teams, with a shared sense of purpose. You'll join a cross-functional squad where you have real ownership of a piece of Perk’s domains, a genuine say in what gets built and the autonomy to make it happen. Each team will decide how to contribute to Perk’s company goals.

We care about impact, and we trust our people to deliver it.

AI is embedded in how we work and what we build. On the engineering side, it spans the whole workflow: our Notion, Jira, Git Hub and Slack are AI-connected so you get up to speed fast, and day-to-day it helps with specifying features, writing and reviewing code, and automated AI PR review on every pull request. When something goes wrong in production, AI surfaces context across systems quickly.

We also embrace agentic coding, using AI as an active collaborator, not just a prompt-by-prompt co‑pilot.

We expect candidates to use AI tools in our coding interviews. The bar is understanding your code and owning what you produce. That reflects how we work every day.

• Shape the bigger picture. You won't just build features, you'll refine the what to build and why. At Perk, senior engineers are expected to go beyond the technical solution and focus on the problem itself. You'll contribute to your squad's quarterly goals and long‑term vision alongside your Product Manager and Engineering Manager.
• Architect for today and tomorrow. When a big change is needed in how our platform works, you'll be the one writing the design documents that lay the foundation. You'll become a guardian of your team's technical quality; spotting areas of investment, proactively managing technical debt, and making sure we don't let "busy work" crowd out the work that truly matters. At Perk, we believe in impact over effort: our customers see results, not the hours behind them.
  
  Your job is to make sure we're always investing our energy where it counts most.
• Lead across boundaries. Your influence won't stop at your own squad. You'll communicate complex ideas across multiple teams, proactively identify who needs to be involved, and drive alignment across the broader organisation. Whether it's coordinating a cross‑sq​uad initiative, contributing to one of our engineering guilds (where engineers from different teams align on shared technical topics), or pairing with architects on solution discovery, you'll operate comfortably beyond your immediate team.
• Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You'll…
