Looking for a Senior Ruby on Rails Engineer to own complex features, build scalable systems, and collaborate with design and product teams while using AI tools for coding. Must have 5+ years of Rails experience and strong coding skills.

We're looking for a Senior Ruby on Rails Engineer to join the Decile Group tech team. Read more here: https://github.com/VCLab-Inc/Engineering
The ideal candidate has real-world production Rails experience and the confidence to own complex, high-stakes features from architecture through deployment. You take pride in writing clean, maintainable code. You use AI tools actively — in your coding workflow, debugging, and design — not because you have to, but because you understand how it makes you faster and sharper. You don't need a fancy degree or big tech pedigree, but you do need to be a strong engineer, a good communicator, and someone who takes ownership seriously.
Basic requirements:
- You'll be expected to complete a Rails coding challenge as part of the interview process (everyone on the Decile Group team has done well on it).
- You must live and work within a few time zones of Pacific (California) time. We are on Zoom and Slack a lot.
- You must be able to take ownership of a complex feature and drive it to completion with minimal hand-holding.
- You should be actively using AI coding tools (Cursor, Copilot, Claude, etc.) as part of your daily workflow.
If you want to work on a product that matters, with a small team that holds a high bar, and grow significantly along the way — you'll fit in at Decile Group.
And we want to work with you too.
What You'll Do
- Own complex features end-to-end. Take a problem from spec to production — architecture decisions, implementation, testing, and deployment. You're accountable for what you ship.
- Build reliable, scalable Rails systems. Work across the full Rails stack: models, services, background jobs, APIs, and the front end. Write code that your teammates can read, extend, and trust.
- Collaborate closely with product and design. Ask the right questions before writing a line of code. Push back when a spec doesn't make sense. Help the team make better decisions with your technical perspective.
- Use AI to write better code, faster. Leverage AI tools throughout your workflow — code generation, debugging, refactoring, documentation. Model what AI-first engineering looks like at Decile Group.
- Improve the systems around you. Identify technical debt that matters, propose solutions, and follow through. Leave the codebase better than you found it.
- Mentor and elevate teammates. Code review with care. Share knowledge generously. Raise the level of the people around you.
What You Bring
- 5+ years of professional Ruby on Rails experience in production environments
- Deep understanding of Rails conventions, ActiveRecord, background processing (Sidekiq/etc.), and RESTful API design
- Strong instincts for performance, security, and maintainability
- Experience with front-end technologies — you can build clean, functional UI and aren't afraid of JavaScript
- Active use of AI coding tools in your daily workflow
- Excellent written communication — your PR descriptions and technical comments are clear and useful
- Comfort owning work independently and flagging blockers early
Nice to Have
- Experience with financial, legal, or compliance-adjacent SaaS products
- Familiarity with fund administration, venture capital, or investment management workflows
- Experience with Hotwire/Turbo/Stimulus or modern Rails front-end patterns
How to Apply:
If you don't tick every box above, we'd still encourage you to apply. We're building a diverse team whose skills balance and complement one another.
Please describe why you are uniquely qualified for this position in the competitive field of Venture Capital to apply, as well as submitting your resume.
Salary and benefits are commensurate with experience.

What you need to know about the Los Angeles Tech Scene
Los Angeles is a global leader in entertainment, so it’s no surprise that many of the biggest players in streaming, digital media and game development call the city home. But the city boasts plenty of non-entertainment innovation as well, with tech companies spanning verticals like AI, fintech, e-commerce and biotech. With major universities like Caltech, UCLA, USC and the nearby UC Irvine, the city has a steady supply of top-flight tech and engineering talent — not counting the graduates flocking to Los Angeles from across the world to enjoy its beaches, culture and year-round temperate climate.
Key Facts About Los Angeles Tech
- Number of Tech Workers: 375,800; 5.5% of overall workforce (2024 CompTIA survey)
- Major Tech Employers: Snap, Netflix, SpaceX, Disney, Google
- Key Industries: Artificial intelligence, adtech, media, software, game development
- Funding Landscape: $11.6 billion in venture capital funding in 2024 (Pitchbook)
- Notable Investors: Strong Ventures, Fifth Wall, Upfront Ventures, Mucker Capital, Kittyhawk Ventures
- Research Centers and Universities: California Institute of Technology, UCLA, University of Southern California, UC Irvine, Pepperdine, California Institute for Immunology and Immunotherapy, Center for Quantum Science and Engineering
