Senior Software Engineer, Product

RevenueCat removes the headaches of building and scaling in-app subscriptions. Since graduating from YC’s S18 batch we’ve grown into the default monetization platform for mobile: we’re in >40% of newly shipped subscription apps, we process $12B+ in annual purchase volume, and we help everyone from a solo dev in Brazil to the OpenAI mobile team understand and grow their revenue.

We’re a remote-first crew of 150+, spread across 25+ countries, and guided by values we actually practice: Customer Obsession, Always Be Shipping, Own It, and Balance. If you want your work to touch hundreds of millions of end-users (and help the developers behind them get paid), you’ll fit right in.

About the Role

We are looking for a Senior Software Engineer, Product to design, build, ship, and own end-to-end product features used by thousands of developers and hundreds of millions of end-users.

This role is product-focused, but deeply technical. You’ll work across frontend, backend, and data boundaries, making thoughtful tradeoffs to deliver reliable, high-quality systems. You’ll be expected to take ownership from problem definition through production rollout and long-term maintenance.

“Product-focused” at RevenueCat means pairing strong engineering fundamentals with good judgment - not trading correctness, reliability, or scalability for speed.

About You

• You are a senior software engineer with strong web development (frontend + backend) fundamentals and a track record of owning production systems end-to-end.

• You care deeply about building reliable software and enjoy working close to real customer problems.

• You’re comfortable working across frontend, backend, and data layers, and you make deliberate, well-scoped changes.

• You’ve shipped meaningful user-facing features to production, supported them over time, and improved systems you didn’t originally design.

• You can turn ambiguous product requirements into clear technical solutions, collaborating effectively with product, design, and other engineers.

• You write high-quality, well-tested code, debug issues methodically, and help raise the engineering bar through thoughtful feedback and mentorship.

Requirements

• 5+ years of professional software engineering experience, with ownership of production systems

• Strong engineering fundamentals: data modeling, debugging, code structure, and testing

• Strong web development fundamentals, including:

  • HTML, CSS and JavaScript fundamentals

  • Component-based UI design and state management

  • Experience with an MVC-style web framework (e.g. Django, Flask, or similar)

  • An MVC framework like Django, Flask, or similar

  • Understanding of HTTP and browser-server interactions

• Experience building and shipping user-facing web applications

• Familiarity with modern frontend frameworks (React, Vue, Angular, or similar), however the interview process will be in React, so brush up on that

• Comfort reasoning about non-trivial SQL queries and data correctness

• Ability to work effectively in a fully remote, async-friendly environment

• Proactive mindset: you notice problems, propose improvements, and follow through

In the first month, you'll:

• Meet frequently with your team and manager to get up to speed

• Familiarize yourself with our tools, processes, and core subscription business concepts

• Complete a First Ship project

• Jump in early: fix some bugs, ship small improvements and weigh in on PRs

Within the first 3 months, you'll:

• Have shipped a medium-sized project successfully

• Understand the main product areas owned by your team and how they work end-to-end

• Be able to scope and work on projects self-sufficiently from idea to improvements post-launch

• Actively participate in code reviews, bug bashes and technical discussions of your team

• Continuously improve areas of the codebase and product of your team

Within the first 6 months, you'll:

• Become the go-to engineer for certain focus areas

• Proactively contribute to architecture direction discussions that impact not just your team

• Debug issues across frontend/backend/data, communicate clearly during incidents, and drive fixes that prevent repeats

• Engage with customers

• Mentor other engineers joining the team and raise the bar through feedback and guidance

Within the first 12 months, you'll:

• Know all the major components of our system and be able to debug complex issues

• Be able to spec and architect large projects, gather feedback and design validation and rollout plans

• Lead your own initiatives for improving our product and system, understanding the current issues and priorities

Technologies you’ll likely work with

• TypeScript

• React

• PostgreSQL

• Python

• Flask

• AWS hosted systems following best practices of deployment, monitoring and reliability.

What we offer:

• Competitive equity in a fast-growing, Series C startup backed by top-tier investors, including Y Combinator

• 10-year window to exercise vested equity options

• Fully remote and flexible work environment

• 4-5 weeks of suggested time off annually for mental, physical, and emotional recharge

• $2,000 USD for workspace setup and $1,000 USD annual stipend for continuous learning
