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.

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 to 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 GitHub 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.

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.

• Raise the bar for everyone around you. Senior engineers at Perk are mentors coaches and bar raisers. You'll support less experienced colleagues through direct mentorship thoughtful feedback during reviews and by modelling what great engineering looks like in practice.
