Senior Software Engineer - Fullstack

Sr Software Engineer

Collaborative. Respectful. A place to dream and do. These are just a few words that describe what life is like at Toyota. 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. At TFS, you will help create best-in-class customer experience in an innovative, collaborative environment.

This role is 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 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

What You Bring

• Bachelor's degree in Computer Science or related field, or equivalent practical experience
• 5+ years of software engineering experience with a strong backend or full-stack focus
• Deep expertise in designing and building serverless architectures on AWS, including:
• Lambda for compute
• API Gateway (REST and APIs) for service exposure
• DynamoDB or Aurora Serverless for data persistence
• Step Functions or other workflow orchestration tools
• EventBridge, SQS, or SNS for event-driven and async communication
• S3 for object storage and data lake patterns
• CloudFront for API acceleration and edge caching
• Strong proficiency in TypeScript and/or Python for backend services — you default to production-quality code and advocate for it across the codebase
• Proven ability to design, build, and maintain RESTful and GraphQL APIs, including API contract design, versioning, error handling, and type-safe tooling (e.g., OpenAPI, GraphQL Code Generator, tRPC)
• Solid understanding of Infrastructure as Code using AWS CDK, CloudFormation, or Terraform
• Experience with observability and monitoring tooling: CloudWatch, X-Ray, Datadog, or similar — you know how to instrument services, trace distributed requests, and respond to incidents
• Strong understanding of security 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 with containerized 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

Added bonus if you have:

• Master's degree in Computer Science or related field
• Experience in the financial services, banking, or insurance industry
• Experience designing multi-account AWS architectures with proper governance and guardrails (AWS Organizations, Control Tower)
• Familiarity with data streaming patterns using Kinesis, MSK (Managed Kafka), or similar
• Experience with GenAI integration on the backend (e.g., Bedrock, SageMaker endpoints, LLM orchestration patterns)
• Experience with CI/CD pipelines and deployment automation (CodePipeline, GitHub Actions, or similar)
• Hands-on experience with GraphQL federation or API gateway patterns for composing multiple services
• AWS certifications (Solutions Architect, Developer Associate, or DevOps Engineer)
• Experience contributing to or maintaining open-source projects
• Experience defining engineering standards, writing ADRs, or leading org-wide technical initiatives

During your interview process, our team can fill you in on all the details of our industry-leading benefits and career development opportunities. A few highlights include:

• A work environment built on teamwork, flexibility, and respect
• Professional growth and development programs to help advance your career, as well as tuition reimbursement
