Staff Software Engineer, Flex

• A Doer — you get things done efficiently, and you're comfortable rolling up your sleeves when something's blocking the team
• An Owner — you take full accountability for what you build, from design through production, and you always have a plan B
• Someone Collaborative — you bring people together to pressure-test ideas rather than working in a silo
• Someone with Precision — your code and your communication are both clear, because ideas only matter once others can act on them
• Someone Resilient — systems break and priorities shift, and you adapt without losing momentum
• Someone Humble — you care more about getting to the right answer than being the one who's right
• Minimum of 8 years experience in software engineering
• Minimum of 6 years experience with Java
• Proven ability to set technical direction and architecture for complex, distributed systems
• Ability to lead and mentor engineers, raising the technical bar across a team or org
• Ability to work on a globally-distributed team with a high degree of ownership
• Experience working with technical and non-technical stakeholders, successfully aligning and setting expectations on scope and delivery
• Experience building robust, fault-tolerant systems with multiple external dependencies
• Experience designing, building, and maintaining data pipelines
• Proficient in Java frameworks and tools used at Flex, including Spring (core/web/boot), Gradle, JUnit, and JVM (memory/performance tuning, GC)
• Experience with Service-Oriented Architecture, REST APIs, Message Queues, and scalable architectures
• Experience with AWS (EKS, Aurora RDS, Elasticache, DynamoDB) and containerization tools

Desirable

• Flex exists to make paying rent work the way real life actually works — smoothing out cash flow, helping renters avoid late fees, and letting them build credit instead of falling behind
• As a Staff Backend Engineer, you'll design, build, and scale the services and integrations behind Payment, Billing, Identity, and partner integrations that keep rent moving on time for renters every month — setting the long-term technical vision and architecture for the systems you own, leading scoping, design, and implementation across teams, driving your own production rollouts to completion with minimal oversight, and working closely with product, design, and engineering peers to solve renters' most pressing problems in small, frequent iterations rather than big, risky releases
• You'll also raise the bar for the engineers around you, mentoring peers and driving consistency and best practices across the org
