Role
Who you are
- 5+ years of experience as a Software Engineer with a focus on building and running reliable, large-scale, distributed systems in production
- 5+ years of operational experience in observability tooling and libraries (metrics, logging, tracing) with experience using Datadog or similar tools (Prometheus, Grafana)
- Proficiency in at least one programming language (Python, Go, Java, or Node.js preferred) for automation and tooling
- Proficiency in incident management, going on-call, and writing post-mortem reports
- Excellent collaboration skills with the ability to influence and educate product engineering teams on reliability and observability best practices
- Hands-on experience with cloud platforms (AWS preferred), container orchestration (Kubernetes), and IAC tools (Terraform, Pulumi)
- Drive and proactivity – everyone here is a builder and executor
What the job involves
- As a Site Reliability Engineer at OnePay, you will play a critical role in ensuring the stability, scalability, and security of the systems that power our financial products, driving reliability practices across infrastructure, platform, and application teams to support millions of customers
- Design, build, and maintain scalable infrastructure and tooling that improves reliability, performance, and availability across OnePay’s platform
- Contribute to the evolution of our observability stack, platform libraries, cloud architecture, and CI/CD pipelines
- Develop automation and monitoring systems to detect, prevent, and remediate incidents before they impact customers
- Partner closely with product and platform engineering teams to embed reliability best practices in design, development, and deployment processes
- Lead root cause analysis and postmortems, driving long-term improvements in resiliency and fault tolerance
- We use the fp-ts library for functional programming with Node/TypeScript running on top of Kubernetes and AWS. We believe great engineers can learn any stack, so you do not need experience with these specific tools, but you’ll ramp up more quickly if you are familiar with functional programming concepts

Our take
Traditional banking hasn't worked for millions of Americans who are underserved or priced out of the system. High fees, minimum balance requirements, and tough credit checks create barriers that keep everyday people from building financial stability. Meanwhile, fintech startups are proving there's a huge demand for simpler, more accessible financial services. But most of these apps still focus on just one or two features, forcing users to juggle multiple platforms to manage their money.
OnePay is Walmart's all-in-one financia platform bringing everything together in a single app. Launched in 2021 through a partnership with Ribbit Capital, OnePay expanded after Walmart acqwuired fintechs Even and ONE in 2022. The platform now includes buy-now-pay-later and, through a new DriveWealth partnership, stock and ETF investing. On top of this, OnePay also serves employers with a B2B financial wellness suite to improve employee stability and engagement.
OnePay is already helping millions of consumers and has earned a 4.8-star app rating. And recently it announced crypto trading for Bitcoin and Ether, further expanding its offerings. With this momentum, the platform is really positioning itself as a true one-stop financial hub.
