Staff Software Engineer - Boston

About the role

Perk (formerly TravelPerk) is the intelligent platform for travel and spend management. Built to tackle the time-consuming, manual work that gets in the way of real work, our tools automate everything from travel bookings to expenses, invoice processing, and more. By eliminating this shadow work that wastes hours, erodes morale, and saps innovation, we're on a mission to power real work, with real impact. We're trusted by more than 10,000 companies worldwide, including Wise, On Running, Breitling, and Fabletics, and we're tackling the 7 hours of lost productivity per employee each week, a $1.7 trillion problem . Founded in 2015, Perk has grown into a global company of more than 1,800 people across 12 offices globally, with headquarters in London and Boston. We combine innovation, control, and simplicity to transform how businesses work and how people feel at work. At Perk, we're driven by our values, like being an owner, delivering a 7-star experience, and working as one team. We value curiosity, purpose, and mindset, not just knowledge, to unlock the power in your potential.

Perk is growing its engineering footprint in North America, and we're looking for a Staff Software Engineer to help us do it right. You'll play a central role in a new product launch as Perk continues its expansion - a rare chance to shape something from the ground up. How we work: At Perk, we believe the best work happens when great people come together in small teams with a shared sense of purpose. Each team has real ownership of its domain, a genuine say in what gets built, and the autonomy to make it happen. We care about impact, and we trust our people to deliver it. What it means to be a Staff Engineer at Perk: Own the technical vision across teams. You'll work across multiple teams to coordinate a shared technical direction. This means contributing to the creation of annual and quarterly plans in collaboration with product managers, engineering managers, and other engineers - and translating that into clear, actionable priorities that teams can work to today. Be hands-on, with purpose. Staff engineers at Perk are mostly hands-on - spending the majority of their time actively contributing within one or two teams, and the rest mentoring engineers, unblocking delivery, and working with dependent teams to move shared projects forward. You won't be pulled into excessive meetings or committees with a focus on impactful collaboration. Shape how we work, not just what we build. You'll take higher-level business goals and turn them into engineering approaches. That means proposing the shape of annual objectives, identifying architectural changes needed for scale, and making sure the team is investing its energy where it counts most - not just staying busy. Raise the bar for everyone around you. Staff engineers are mentors and multipliers. You'll support engineers through direct mentorship, design reviews, and pairing. You'll help explain technical complexity to the wider business - including why certain things take the time they do - and help the whole team level up their skills to better apply them to the domain. Lead across boundaries. Your influence won't stop at your own team. You'll coordinate across squads, contribute to engineering initiatives, and drive alignment across the broader organisation. When there are dependencies or blockers, you'll be the one connecting the dots. Desired skills and experience: Product engineering mindset: you work end to end - from understanding customer problems alongside product, through to deployment and measuring impact. Technical skill alone isn't enough; you need to be able to own a problem fully. Cross-team technical leadership: proven experience coordinating significant, multi-team technical initiatives where you've had to manage dependencies, align stakeholders, and keep a longer-horizon project moving. Architectural judgment: ability to design scalable, evolvable systems and articulate a clear technical roadmap - balancing long-term thinking with pragmatic, near-term delivery. "You build it, you run it" experience: you've run your own services - monitoring, testing, rolling out, and operating them in production. The tools may differ; the mindset shouldn't. Domain complexity: experience working in a domain with significant underlying complexity - ideally flights or travel, but also fintech or any industry where you've had to build reliable, customer-facing products on top of messy, constrained underlying systems. Backend-heavy, full-stack comfortable: our stack is roughly 80% backend, 20% frontend. You should be comfortable across both, with the depth in backend systems. We use Python and AWS;
