About The Position

Etsy is looking for a passionate Staff Software Engineer to help us enable data-driven learning and decision-making for our Experimentation initiative. Our initiative empowers teams across Etsy to run fast, trustworthy, and scalable experiments — by laying the foundation for how we test ideas, measure impact, and continuously improve our customer experience. This is a high-impact opportunity to influence the technical direction of experimentation at Etsy, which affects feature development across the company. We're looking for someone who thrives in collaborative environments, challenges the status quo, and is a creative problem solver. Additionally, we are looking for someone who embodies Etsy's blameless engineering culture, as we value clear communication, honest feedback, and empathy as the foundation for how we work together and get things done. This is a full-time position reporting to the Engineering Manager, Experimentation. In addition to salary, you will also be eligible for an equity package, an annual performance bonus, and our competitive benefits that support you and your family as part of your total rewards package at Etsy. For this role, we are considering candidates based in the United States. Candidates living within commutable distance of Etsy's Brooklyn Office Hub or in the San Francisco Bay Area may be the first to be considered. For candidates within commutable distance, Etsy requires in-office attendance once or twice per week depending on your proximity to the office. Etsy offers different work modes to meet the variety of needs and preferences of our team. Learn more details about our work modes and workplace safety policies here . You would join the Experimentation Orchestration team, which focuses on making experiment setup simple, intuitive, and reliable. We build the core services, APIs, and tools that help teams configure and launch experiments with confidence. Whether it's feature flagging, observability, traffic allocation, or ensuring a consistent user experience, our work sits at the heart of a seamless experimentation workflow. Our mission is to make testing new ideas effortless — so teams can move faster, learn more, and build better products for our buyers and sellers.

Responsibilities

Partner with engineers, analysts, and product managers — both within and beyond the Experimentation initiative — to improve Etsy's experimentation platform. Your work will focus on experiment configuration, orchestration, and event logging.
Take initiative to lead, design, and implement solutions that keep our platform at the forefront of industry standards — and ultimately a reference point for experimentation excellence.
Mentor and uplevel others within the team and across Etsy to help them grow as software engineers.
Advocate for experimentation best practices across engineering teams and contribute to a strong culture of learning and continuous improvement.
Play a key role in driving technical and product direction through thoughtful decision-making and collaboration.
