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
