Role
Who you are
- 5+ years of professional engineering experience shipping production code to write clean, maintainable, and well-tested code
- Hands-on expertise with modern AI tooling, including LLM APIs, agent frameworks (LangGraph, Claude SDK), developer tools (Cursor/Claude Code), MCP server development, and familiarity with LLM evaluation techniques (prompt regression testing, human-in-the-loop review, and automated eval pipelines)
- Systems integration experience, including a working knowledge of REST APIs, data pipelines (SQL), and cloud infrastructure (GCP/AWS)
- A "Product Mindset"—proactively finding friction points, designing solutions, and presenting trade-offs to all audiences—along with the drive and proactivity to "walk across org lines" to get things done
What the job involves
- As a Platform Engineer (AI & Automation) at OnePay, you are the technical force responsible for transforming AI strategy into production reality
- You will embed within cross-functional teams to design, build, and deploy the agentic systems and intelligent tooling that automate complex workflows and 10X their impact
- Operate as an AI-native engineer, utilizing tools like Cursor and Claude Code to rapidly prototype, deploy, and ship production-grade AI agents and automation workflows that solve high-stakes business problems in cross-functional organizations
- Lead structured discovery sessions with business stakeholders and Subject Matter Experts to surface requirements, assess feasibility, and translate manual processes into clear, performant technical specifications and agentic architectures
- Build, maintain, and secure robust integrations between the core SaaS stack and custom AI services, instrumenting monitoring, guardrails, and evaluation frameworks to ensure all AI-driven workflows are accurate, compliant (including PII handling and audit logging), and resilient at scale
- Act as a technical force multiplier by empowering and educating internal partners to adopt AI-first mindsets, and create reusable playbooks, architecture decision records, and handoff documentation to enable teams to maintain and extend what you build
- We use Node and TypeScript on the server, leveraging the NestJS framework within a microservice-oriented architecture running on Kubernetes and AWS. On the client side, we build and ship product features for iOS, Android, and web platforms using React Native. While you don’t need experience with our exact stack, familiarity with modern software engineering practices will help you ramp up quickly

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.
