Senior Rails Full-Stack Developer
About Hubstaff Hubstaff helps remote teams work smarter with industry-leading workforce analytics, time tracking, scheduling, and payroll automation software used by 140,000+ users globally. We’ve been fully remote for over a decade and believe remote work is one of the biggest shifts in modern work. We’re profitable, product-led, and building for the long term. The Role We’re hiring a Senior Rails Full-Stack Developer to join our Growth team — a fast-moving engineering group focused on experimentation, user experience, and business impact. This isn’t a traditional feature factory role. Growth engineers at Hubstaff are deeply involved in ideation, experimentation, analytics, and outcomes — not just implementation. We’re looking for engineers who are driven by outcomes over output and who thrive in environments where speed, learning, and ownership matter. Success in this role means thinking beyond tickets and contributing to the full lifecycle of experiments: ideation, implementation, measurement, iteration, and learnings. You’ll work closely with Product, Design, Data, and Marketing to launch experiments quickly, learn fast, and improve conversion, activation, retention, and customer experience across the platform. What You’ll Do Build and scale features using Ruby on Rails, Hotwire, Tailwind, and modern frontend tooling Launch rapid growth experiments with ultra-fast turnaround times Own projects and experiments from idea to outcome — not just delivery Scope-cut strategically to maximize learning velocity and business impact Work with tools like Statsig, Segment, Metabase, and Customer.io Analyze metrics, events, experiment results, and user behavior to guide decisions Balance technical quality with experimentation speed Improve performance, reliability, and UX across the platform Collaborate asynchronously with a high-performing remote team What We’re Looking For 5+ years building production web applications Strong Ruby on Rails experience Strong frontend experience with Hotwire/Turbo/Stimulus + Tailwind Experience with React, Vue, or similar modern JS frameworks Product-minded engineer with strong ownership mentality Comfortable operating in fast-moving, experimentation-heavy environments Strong understanding of metrics, event tracking, experimentation, and data-informed decision-making Ability to think through tradeoffs, risks, and business impact — not just technical implementation Bias toward action with a “ship, learn, iterate” mindset Experience working remotely and asynchronously Stable work history with multi-year tenure preferred
