As one of the world’s most admired brands, Toyota is growing and leading the future of mobility through innovative, high-quality solutions designed to enhance lives and delight those we serve. We’re looking for talented team members who want to Dream. Do. Grow. with us.

An important part of the Toyota family is Toyota Financial Services (TFS), the finance and insurance brand for Toyota and Lexus in North America. While TFS is a separate business entity, it is an essential part of this world-changing company- delivering on Toyota’s vision to move people beyond what’s possible.

Who we’re looking for

At TFS, we’re building next-generation products that redefine mobility for millions of customers worldwide. We’re looking for a Sr Software Engineer — an individual contributor who brings deep backend expertise, strong full-stack instincts, and the technical chops to deliver high-quality systems end to end.

This role is for an engineer who thrives in the code: the one who builds reliable services, debugs the hard problems, contributes to architecture discussions, and consistently raises the quality bar for the team. You’ll work closely with your team, take ownership of complex features, and help shape how we build software.

This position is based in Plano, TX. The selected candidate will be expected to reside within a commutable distance of this location.

Key Responsibilities

• Design, build, and maintain full-stack features — from APIs and serverless services to the data models and event-driven workflows that power them
• Lead technical design reviews, architecture discussions, and RFC processes — driving alignment across engineering teams
• Identify and resolve systemic issues: performance bottlenecks, reliability gaps, scaling constraints, and tech debt that slows teams down
• Own complex debugging and troubleshooting across the full stack — from API latency to infrastructure misconfigurations to distributed system failures
• Follow and contribute to engineering best practices: code quality, testing strategies, observability, and deployment safety
• Collaborate closely with Engineering Managers, Product, and Front-End Engineering to shape roadmaps and ensure technical feasibility
• Proactively communicate technical risks, tradeoffs, and recommendations to both engineering and non-technical stakeholders

  • EventBridge,SQS, orSNSfor event-driven and async communication
  • S3for object storage and data lake patterns
  • CloudFrontfor API acceleration and edge caching
• Strong proficiency inTypeScriptand/orPythonfor backend services — you default to production-quality code and advocate for it across the codebase
• Proven ability to design, build, and maintainRESTful and GraphQL APIs, including API contract design, versioning, error handling, and type-safe tooling (e.g., OpenAPI, GraphQL Code Generator, tRPC)
• Solid understanding ofInfrastructure as CodeusingAWS CDK, CloudFormation, or Terraform
• Experience withobservability and monitoringtooling: CloudWatch, X-Ray, Datadog, or similar — you know how to instrument services, trace distributed requests, and respond to incidents
• Strong understanding ofsecurity best practices: IAM policies, least-privilege access, secrets management (Secrets Manager, SSM Parameter Store), and data encryption at rest and in transit
• Deep experience debugging complex issues across distributed systems — network traces, distributed tracing, log analysis, and profiling
• Experience with testing at all levels: unit, integration, contract, and load testing for distributed systems
• Familiarity withcontainerized workloads(ECS Fargate, Docker) for services that don't fit the serverless model
• Strong written and verbal communication — you can write a clear RFC, lead a design review, and explain a complex tradeoff to a non-technical stakeholder
