Summary

This role is ideal for a Senior Full Stack Engineer who thrives in "zero-to-one" environments. You should have at least 6 years of experience and a background as a founder or an early employee at a fast-paced startup. The team is looking for an "A-player" who can handle the technical demands of Ruby on Rails and React while also acting as a product owner who isn't afraid of ambiguity. The standout feature of this position is the "startup within a startup" dynamic—you get the speed and autonomy of the Checkr Trust lab backed by the massive resources and stability of a Forbes Cloud 100 company. The compensation is highly competitive ($185k–$218k base), complemented by premium benefits like 100% medical coverage, a $25k fertility/adoption stipend, and daily catered lunches in the San Francisco office. **You might be a good fit if you:** * Have experience building scalable APIs and asynchronous architectures for millions of users. * Enjoy a hybrid schedule (3 days/week in SF) and want to influence product direction directly. * Prefer shipping MVPs and running experiments over long, rigid development cycles. * Are comfortable working across the full stack with Ruby on Rails and React.

Checkr has over 100,000 customers including DoorDash, Coinbase, Lyft, Instacart, and Airtable.

We’re a team that thrives on solving complex problems with innovative solutions that advance our mission.

Checkr Trust is building safer communities by providing our customers with risk signals about its users. Every year, our team provides insights on tens of millions of users across multiple verticals: online dating, car rental, short-term rentals, and many more. We acquire, analyze, and deliver insights in smart, scalable ways that help organizations identify and mitigate risk.

Trust is part of the Checkr start-up lab: we operate with the speed of a small startup, while enjoying the leverage and resources of a known technology brand.

Since launching, we’ve seen significant growth and we are looking for a Senior Full Stack Software Engineer to play a pivotal role in the continued growth of our startup. As part of our small team, you will be empowered to take significant end-to-end ownership - from idea to execution to real customer and business impact.

What you’ll do:

• Work closely with customers, engineers, and leaders to design, build, and launch new products.

• Take full ownership of the entire process of developing end-to-end applications – from shaping the idea to delivering the finished application.

• Build and improve APIs, including integrating with third-party services to expand what our products can do.

• Embrace a customer-centric, product-first approach – partner directly with customer success, customers and stakeholders to better understand their needs and turn those into useful features.

• Keep code reliable and easy to maintain with solid testing, thoughtful reviews, and good practices.

• Run and measure product experiments, using what you learn to guide future development.

• Building scalable APIs and asynchronous event-based architecture that can reliably handle very high traffic.

• BS/MS degree in either computer science or an engineering discipline.

• Have founded or held early roles at successful fast-paced startups.

• 6+ years of full stack software development experience.

• Advanced knowledge in Ruby (Rails), Javascript (React), or similar languages/frameworks.

• Experimentation mindset: autonomy and empowerment to validate a customer need, get team buy-in, and ship a rapid MVP.

• Early-stage approach: comfort with ambiguity, balancing speed and perfection, and the confidence and curiosity to help guide product direction.

• An A-player mindset with a strong bias for action: you raise the bar, move with urgency, stay resilient through ambiguity, and take ownership to deliver meaningful outcomes.

• Experience building scalable technical architecture that can scale to 10mm+ users (including observability tooling, container orchestration, etc).

• Expertise in data analysis and processing.

• Experience building and working with scrapers and scraping technology

• A fast-paced and collaborative environment

• Learning and development allowance

• Competitive compensation and opportunity for advancement

• 100% medical, dental, and vision coverage

• Up to 25K reimbursement for fertility, adoption, and parental planning services

• Flexible PTO policy

• Monthly wellness stipend

• Working at a startup within a startup
