About The Position

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. Toyota does not offer support or sponsorship of job applicants for employment-based visas or any other work authorization for this role now or in the future. You must have the right to work in the United States and not require Toyota support or sponsorship for immigration-related employment (e.g., H-1B, O-1, E-3, H-1B1, TN, F-1 OPT, F-1 STEM OPT, F-1 CPT, ‘job flexibility benefits’ [also known as I-140 or Adjustment of Status portability], etc.) now or in the future. You should not apply for this role if you will require Toyota to assist with immigration support or sponsorship now or in the future.

Requirements

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 HTTP 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

Nice To Haves

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

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
