To help us get there, we’re hiring a Growth Engineer to design experiments and implement features that drive user acquisition, activation, retention, and engagement.

About us:

Instrumentl is a hypergrowth YC-backed startup with over 5,000 nonprofit clients, from local homeless shelters to larger organizations like the San Diego Zoo and the University of Alaska. We are building the future of fundraising automation, helping nonprofits to discover, track, and manage grants efficiently through our SaaS platform. Since 2015, our customers have used Instrumentl to find, win, and manage over $6.7 billion in grant funding.

Our charts are dramatically up-and-to-the-right 📈 — we’re cash flow positive and doubling year-over-year, with customers who love us (NPS is 65+ and Ellis PMF survey is 60+). Join us on this rocket ship!

As a Growth Engineer at Instrumentl, you’ll collaborate closely with our Product, Marketing, Design, and Data teams, playing a pivotal role in accelerating our company’s expansion through rapid iteration and data-driven decision-making. Get to know us at !

Our ideal candidate is eager to learn, willing to experiment, and excited to empower both teammates and customers to accelerate social progress and propel innovation.

The Instrumentl team is fully distributed (though if you’d like to work from our Oakland office, we would love to see you there). For this position, we are looking for someone who has significant overlap with Pacific Time Zone working hours.

• Design, build, and deploy experiments and features, using Ruby on Rails to enhance user experiences and drive key growth metrics.
• Work side by side with our Product, Marketing, Design, and Data teams to ensure that our best-in-class product retains its crown.
• Maintain and improve our growth experimentation platform, ensuring robust and reliable experiment tracking and analysis.
• Implement and analyze A/B tests to validate hypotheses and inform product decisions.
• Own problems from end to end, managing complexity and engaging directly with stakeholders to develop short-term and long-term solutions.
• Apply a product-focused mindset, balancing speed, quality, and user experience in all deliverables.
• Continuously assess team workflows and go to market processes to identify opportunities where automation and AI can drive efficiency, scalability, and speed.
• Uphold Instrumentl’s high standards for product quality and mentor newer team members to do the same.

• Experienced: you’ve been a software engineer for 3+ years, with a strong emphasis on Ruby on Rails development. Startup experience and comfort operating in fast, scrappy environments is a huge plus!

• Customer-focused: you take pride in delivering exceptional user experiences—from first touch to deep engagement—and love being part of projects that help users quickly realize value.
• AI-native mindset
  : you naturally reach for automation and AI-powered tools to speed up workflows, eliminate repetitive tasks, and improve outcomes. You see LLMs and related technologies not just as features, but as tools to rethink how we work.
• Process optimizer: you have a sixth sense for spotting inefficiencies and love digging into systems to streamline them - whether that means writing a script, wiring up an API, or prompting an LLM. You’re energized by finding clever ways to save time and scale impact.
• Collaborative: you thrive in a cross-functional environment involving product managers, designers, marketers, and data analysts, and you value the unique perspective each person brings to the table.
• Experimental: You’re comfortable with rapid iteration, feature flagging, and A/B testing. You have experience (or are excited by the idea of) running experiments at…
