Babylist is hiring Senior Software Engineers to join our engineering organization. You'll work on systems that power a $1B+ GMV marketplace, serving over 9 million families annually. Our engineering teams build everything from advertising platforms and commerce tools to registry systems and health products. During the interview process, you'll learn about different teams and we'll identify the best fit based on your skills and interests.

• Revenue & Growth: Advertising partnerships, commerce features, lifecycle marketing, and growth experiments
• Product & Experience: Registry tools, shopping flows, health product experience, and customer-facing features
• Platform & Infrastructure: Developer tools, core services, monitoring, and foundational systems

We’re looking for builders — engineers who are excited about solving hard problems, moving fast, and helping invent what AI-first software development looks like at Babylist.

• A high-performing engineer with 6+ years of experience delivering end-to-end solutions that drive business growth
• You thrive in a quickly growing environment and are excited to lead business-critical projects to unlock new capabilities
• You have experience testing, monitoring, and running production software systems and are focused on continuing to grow your skills
• You are a talented programmer with React and Ruby on Rails experience (or similar tech stack experience like Python/Django or Javascript/Node.js with strong desire to learn Ruby on Rails) and are excited about further developing your craft and quality of work
• You have a passion for identifying gaps in team processes or execution and love driving impactful improvements
• You're adaptable and open to working on different types of problems, from revenue systems to customer-facing features to infrastructure
• Past experience in e-commerce, consumer growth marketing, adtech, or marketplace systems is a plus but not required
• You pay close attention to detail
• You actively use AI coding tools (Copilot, Cursor, Claude Code, or similar) as part of your daily workflow, bring the architectural judgment to know when to trust AI-generated code and when to course-correct, and are comfortable with a higher experimentation rate — including bets that don’t pan out

• Provide leadership around process, tooling, systems, and software architecture. We benefit from more knowledge and learning how others solve problems. You will feel excited to bring in new ways of solving problems.
• Improve and help maintain existing systems — and lead the team in adopting AI-first approaches to do it faster. As a Senior Engineer, you’re expected to help define how we use AI tooling to accelerate code quality, reduce friction, and raise the bar on what’s possible. This includes knowing when AI-generated code needs architectural correction, not just acceptance.
• Work closely with product managers, designers, and data teams to design, implement, and deploy systems that support our growing business
• Make architectural decisions that balance speed, quality, and long-term maintainability
• Work in a close, supportive team solving real-world problems and making decisions
• Mentor other team members through design and architecture planning, code reviews, and knowledge-sharing sessions

Babylist is remote-first with team members across the U.S. and Canada who move fast, think smart, and use AI as part of how they work every day — not as an experiment, as an expectation. We come together twice a year to build the relationships behind the work, and we hire people who are genuinely excited about what's possible and prove it through how they show up.

• We work with focus and intention, then step away to recharge
• We believe in exceptional management, and we invest in the tools and the time to connect with colleagues
• We build products that positively impact millions of people's lives
• AI is part of how we work, not a side experiment. You'll have leading tools like Claude and ChatGPT from day one, with no waiting on access, so the busywork gets handled and your judgment goes where it counts

• Competitive pay and meaningful opportunities for career advancement
• We believe technology and data can solve hard problems
• We're committed to career progression and performance-based advancement
