Staff Software Development Engineer (Hybrid @ Bellevue, WA or Remote @ Florida) at Offerup · Lumi · Lumi

Responsibilities

The OfferUp Business team owns the platforms that power every business vertical on our marketplace; Storefronts, Auto Dealers, Services, Rentals, and Jobs. Our customers aren t casually browsing; they re running businesses on top of what we build, so every feature we ship has a direct, measurable impact on their livelihood and on OfferUp s revenue. We operate the full stack end-to-end: including microservices that handle some of the highest RPS and TPS in the company, and integrations with partners like Stripe and Shopify. We move fast, instrument everything, and treat experimentation as a first-class part of the workflow. We ve barely scratched the surface of what these verticals can become, and the roadmap is wide open for someone who wants to shape it.
At many organizations, your role begins and ends with the code. On our team, we’re different. You own a feature from concept to fruition. Your responsibilities will include everything from writing well architected and thoroughly tested code, to rolling out the feature by analyzing metrics. You also get to take ownership beyond your technical area by working with cross-functional team members.
As a Staff Software Engineer on the Business team, you ll be both a hands-on builder and a technical leader. You ll set the technical direction for the team, ship high-impact features with strong operational rigor, raise the bar on engineering quality across the org, and find creative ways to unlock new business surfaces.
Here’s more of what you will get to do:
Define the multi-quarter technical roadmap for the Business team and align it with company priorities
Design and operate high-throughput microservices where reliability, latency, and observability are non-negotiable
Work collaboratively with cross-functional teams to design and implement new features across all five business verticals
Communicate complex technical designs to both technical and non technical stakeholders
Collaborate with engineering teams across OfferUp to surface common pain points, develop solutions, and evangelize best practices
Drive experimentation strategy, design A/B tests, interpret results, and use data to decide what ships
Make pragmatic calls on what to refactor, replace, or leave alone, and bring the team along on the reasoning
Support, mentor, and grow other engineers on the team
