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 Senior Staff Software Engineer, you'll oversee the technical roadmap for the team, working across APIs, SDKs, and Web experiences. You will work with teams across the organization including Engineering, Product, Design, Infrastructure, Sales, Partner and Customer Success to ensure that the technical strategy meets our goals.
We expect you to be hands-on and execute work as an individual, and build products that allow for flexibility as we evolve our product offerings.
About Our Team!
We have some really exciting teams who are looking for an amazing engineer like you! Check them out!
- Partner Integrations – Partner integrations work to standardize APIs, tools, and processes that let external partners connect to Flex for data sharing and payments across entry points like Flex Anywhere
Who thrives here?
- 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.
