Working in Product means making bold decisions with the data you have. You're the type that always asks, “Is there a better way?” From product managers to designers to researchers, the people who thrive here are strategic by nature, curious by default, and comfortable sailing without a full map. So if you challenge assumptions and know how to bring multiple stakeholders together, the Fiverr Product team might be your place.

What am I going to do?:
Make an impact: Drive outcomes across the Fiverr marketplace for clients and freelancers alike — but expect the specific area you own to shift. Where you focus is set by our strategic Bets, and those change as the Bets change. Lead a multidisciplinary team: Collaborate with engineers, designers, and data scientists to drive product delivery and innovation. Turn data into decisions: Define how we collect, validate, and use the signals that power the product — translating data into reliable inputs for better decision-making. Drive the end-to-end user experience: Continuously improve the surfaces and flows that users rely on, from onboarding to ongoing engagement. Develop and execute roadmaps: Create strategic product roadmaps and lead their execution, balancing short-term delivery with long-term platform thinking. Collaborate across teams: Work with stakeholders across the organization to align on a shared direction and amplify impact. How we actually work: Fiverr's product org runs on strategic Bets — leadership sets a small number of company-wide Bets each half, derived directly from our OKRs, and most of our capacity flows there. Teams get assigned to whatever Bet most needs them next, not necessarily their "home" domain. That means the traditional model — a fixed squad with permanent mission and task ownership — doesn't really apply here. Scope, team composition, and priorities move as the Bets move, sometimes mid-cycle. You're joining a team and a mission-driven org, not a fixed job description, and the right person for this role reads that as the exciting part, not the risky part.

Equal opportunities:
At Fiverr, we know that talent has no single face. We welcome talent from everywhere and everyone because it makes everything we build better. Need accommodations? Just ask. And if this role excites you but you don't tick every box, apply anyway. The best people rarely fit the mold exactly.

We are growing and are looking for a Backend Engineer to join our mission in developing life saving software!

Your responsibilities will span from design to implementation of a complex, time critical, micro services based system that processes high volumes of data. You will collaborate with various teams, including the algo, data and product teams, in order to deliver the best code using high end technologies.

We're looking for a Senior Backend Engineer to own core infrastructure that powers our platform - from the pipelines that move and process data at scale, to the systems that keep our engineering org shipping fast and reliably. This is a technical leadership role: you'll set architecture direction, raise the bar on engineering practices, and mentor other engineers, while staying deeply hands-on.

You'll operate in an organization that expects AI-native ways of working. Using tools like Claude, Cursor, Hermes or LangGraphor isn't a bonus here - it's the baseline for how we build, and we expect you to help the rest of the team level up on it too.

What Youll be Doing:
Own core backend infrastructure - design and build scalable, reliable Node.js/TypeScript/Python/Go services that other teams and systems depend on.
Build and scale data pipelines - architect the infrastructure that processes and moves large volumes of data reliably, efficiently, and at scale.
Elevate test & validation infrastructure - build the automation, tooling, and CI/CD systems that let engineering ship fast without breaking things, and that make quality and reliability measurable.
Set technical direction - make architecture decisions with company-wide impact, drive design reviews, and establish engineering standards and best practices.
Mentor and multiply - level up other engineers technically, and help shape a fast, high-ownership engineering culture as the team grows.
Lead with AI-native workflows - use AI-assisted development tools daily to move faster without sacrificing architectural quality, and champion their adoption across the team.
