Work In Tech

At Fellow, we’re on a mission to give every employee their own AI-powered Chief of Staff, an assistant that understands your meeting discussions, surfaces key insights, answers questions, and takes action so you can focus on what matters most.

We’re looking for a Senior Software Engineer to join our fast-paced Growth team. In this high-leverage role, you’ll run product experiments that boost acquisition, retention, virality, and paid conversion. Small wins here create outsized impact, making this one of the most exciting and strategic roles in the company.

Why Fellow?
Fellow is a remote-first, Series A startup backed by Craft Ventures, iNovia, and Felicis. Our founders previously built Fluidware (acquired by SurveyMonkey), and we’re now helping the world’s best teams—from Shopify, HubSpot, and Warner Media, to startups across the globe—make meetings more productive with the power of AI.

We’re shaping the future of work with a category-defining platform, and we’re just getting started.

About the Role
As a Senior Software Engineer on the Growth team, you’ll be embedded in a cross-functional squad working directly with product, design, data, and QA to build, test, and scale product-led growth experiments.

You will:

• Drive growth experiments that improve key product metrics: acquisition, retention, virality, and paid conversion.
• Build full-stack features using technologies like React, TypeScript, Django, Python, GraphQL, and Relay.
• Move fast and learn fast: we ship multiple experiments weekly and measure results rigorously.
• Collaborate with Growth leadership, including the Head of Product Growth, to align technical work with strategic business outcomes.
  
• Use data to drive decisions, set hypotheses, and define success metrics.
• Maintain a high-quality codebase with strong testing and documentation practices.

About You

You might be a great fit if you:

• Have 5+ years of full-stack development experience, ideally in high-growth product environments.
• Thrive in fast-paced, experiment-driven teams where speed and impact go hand-in-hand.
• Are curious about growth metrics, and motivated by understanding what moves the business.
• Have experience with feature flagging and experimentation platforms (e.g., GrowthBook, LaunchDarkly).
• Are excited about AI and tools like Cursor to supercharge your productivity.
• Love owning features end-to-end—from writing technical specs to monitoring post-release impact.
• Communicate clearly and collaborate well across disciplines.
• Have worked in remote environments and enjoy asynchronous collaboration.
  

Bonus: Experience in B2B SaaS or building products for product-led growth.

Our Engineering Culture

On the Engineering team at Fellow we value rapid delivery, craftsmanship, and continuous learning. We ship small experiments every week, measure their impact, and iterate quickly while keeping reliability and polish front-of-mind. We lean on AI tools and rigorous code review to raise the bar, share knowledge through book clubs and lunch-and-learns, and unleash big ideas at our twice-yearly hackathons. Above all, we collaborate openly, give fast feedback, and celebrate wins as a team.
