About the team/role

As a Senior Software Engineer on the MVR team, reporting to the Engineering Manager, you will build and evolve the systems that power Checkr's motor vehicle record screenings, helping customers make safe, fair, and fast decisions about the drivers on their platforms. You will lead the design and execution of reliable, scalable services across the MVR lifecycle, from how records are ordered and retrieved from data sources to how they are processed, normalized, and delivered in customer reports. You will partner closely with Product, Supply Chain Operations, Product, and Business Operations to shape the platform's long-term architecture and ensure MVR screenings scale alongside Checkr's growth.

What you’ll do

• End-to-End Ownership: Lead the development lifecycle for complex MVR features, from ideation and technical design through implementation, release, and ongoing operation.

• System-Level Strategy: Define and drive the technical direction for MVR systems, identifying architectural improvements that increase reliability, reduce turnaround time, and make the platform easier to extend.

• Cross-Functional Partnership: Partner with Data Supply Chain, Supply Chain Operations, Product, and Operations to translate data provider realities and customer needs into scalable technical solutions.

• Engineering Excellence: Design, build, and maintain high-performance services that meet the highest standards for data accuracy, security, and compliance.

• Operational Reliability: Proactively identify systemic risks across MVR data flows, lead incident response and root-cause analysis, and drive durable fixes that prevent recurrence.

• Technical Leadership: Mentor engineers on the team and across the organization, raising the bar on code quality, design reviews, and engineering practices.

• AI-First Mindset: Embrace an engineering culture where AI tooling is standard practice, leveraging the latest AI-assisted tools, models, and assistants to amplify your impact.

•  

What you bring

• Senior Backend Expertise: 5+ years of experience building scalable backend systems, with strong proficiency in at least one modern programming language and a deep understanding of relational databases, ORMs, and RESTful APIs.

• Distributed Systems Experience: A proven track record of designing and maintaining reliable distributed systems, including hands-on experience with microservices, CI/CD, and asynchronous or event-driven architectures.

• Systems Thinking: The ability to reason about a platform end to end, weigh architectural trade-offs, and design solutions that hold up as data sources, volume, and product requirements change.

• Data Integration & Quality: Experience integrating with external data providers or third-party APIs, and building pipelines that handle inconsistent, delayed, or incomplete data with accuracy and resilience.

• Ownership & Communication: Full-cycle ownership of your work and the ability to communicate technical decisions clearly to both engineering and non-engineering partners.

• 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.
