About the role:
We've built a financial empowerment platform that helps businesses of all sizes make a real impact on employee financial wellness, and the systems you architect here directly power that mission.
We're looking for a Staff Developer who genuinely cares about building things well. You'll take on the hardest technical problems, champion best practices, and bridge the gap between where our systems are today and where they need to be as we scale. If you're the kind of person who gets pulled toward hard architectural questions, enjoys mentoring, and reaches for data when something needs solving, this is a role where that curiosity gets put to good use every day.
Your impact:

• Design and maintain scalable, secure software architectures aligned with business goals, resulting in robust and reliable systems
• Introduce and implement best practices around OO, DDD, and microservices where appropriate
• Use AI to streamline processes, reduce friction, and give time back to developers for the work that matters
• Implement and enforce coding standards and best practices, driving measurable improvements in code quality and maintainability
• Conduct regular code reviews with feedback that meaningfully reduces bug counts and improves software performance
• Facilitate clear communication between development teams, product managers, and other stakeholders to keep projects aligned
• Use data as your north star - leverage application data, third-party data, and our data warehouse to analyze and solve problems around both product impact and performance
• Participate in our agile development process: sprint planning, story grooming, and standups
• Champion our SDLC and secure coding practices across everything you ship

You bring:

• 6+ years of experience with Ruby on Rails
• A mastery of fundamentals: solid coding principles, domain-driven design, performant code and queries, unit and integration testing
• Experience leading projects involving scale, concurrency, queuing, background processing, and efficient ingestion of third-party data
• A security mindset: OWASP, secure development, and SOC-2 processes
• Experience deploying resources outside of app dev (AWS, RDS, queues, serverless)
• Track record of using AI to simplify workflows, eliminate bottlenecks, and shift focus toward meaningful work
• Strong data engineering skills: complex SQL queries, optimization, ETL
• Comfortable working across data warehouse and analytics tooling to surface insights, track down errors, and inform performance improvements

Research shows that while men apply to jobs when they meet an average of 60% of listed criteria, women and other marginalized folks tend to only apply when they check every box. Think you have what it takes, but not sure you check every box? Apply to the role anyways. We'd love to talk and determine together whether you could be a great fit!
Why you'll love working at ZayZoon:

• Permanently Remote: Work from a desk, a coffee shop, or in the great outdoors - our jobs are fully remote, forever
• Flexible Time Off: Whether it's a longer vacation to explore new horizons, a series of short breaks for regular rejuvenation, or stepping away for a new level of mastery in a skillset - our "You-do-You" time off program caters to the diverse and evolving lifestyles of our team with a maximum of 6 weeks vacation
• Instant Benefits: All full-time employees get access to medical, vision, and dental benefits from their very first day including increased mental health coverage and a wellness stipend
• Plus: Inclusive parental leave top-up, earned wage access, real time market data for salaries, a supportive culture for lifelong learners and more
