Senior Software Engineer

How We Build

Babylist is in the middle of a fundamental shift in how software gets made, and we are not tiptoeing into it. We are rebuilding our engineering culture around a simple belief: AI changes everything. How teams are structured, how decisions get made, how fast ideas become working software. Our engineers own problems end to end, working directly with product, design, and business partners with short feedback loops and real stakeholder access. We ship, learn, and iterate fast. When something is not working, we throw it out and start over — project failure and personal failure are not the same thing here. AI tools are as natural to our workflow as an IDE or version control. We are not exploring this, we are living it. Our engineers use AI to explore tradeoffs, pressure-test designs, and move from problem to solution in hours instead of days. They generate code with AI so they can stay focused on the decisions that actually require human judgment — not the routine ones. More velocity means more time for craft: better test coverage, stronger architecture, and deeper customer understanding. We hold ourselves to a higher quality bar because of AI, not in spite of it. We are building this playbook in real time, and we are looking for people who want to build it with us. If you have already changed how you work because of AI — or you are ready to — and you care more about shipping something great than following a prescribed process, we should talk.

What the Role Is

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.

The work spans:

• 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.

Who You Are

• 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

How You Will Make An Impact

• 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

About Compensation

We use a market-based approach to compensation. The starting salary range for this role is:

 $186,800 to $233,500 + target 15% annual bonus

Your starting salary will be based on your location, experience, and qualifications, with increases over time tied to performance, role growth, and internal pay equity.
