[Hiring] Backend Engineer @hireVouch

Role Description

We're looking for an API engineer to join our core API team and help scale our platform serving millions of users and handling thousands of requests per second. You'll work on the critical infrastructure that powers both our public API (used by external developers) and internal tools, managing user data, task orchestration, billing, permissions, and asset management. This is a high-impact role on a mature, production system. You'll build enterprise features, optimize database performance, design async workflows, and ensure reliability at scale. If you're passionate about API development, love TypeScript, and want to own systems end-to-end, this is the role for you.

A peek at our technical stack:

• API endpoints for real-time collaboration and media asset management are written in TypeScript and run in ECS containers on AWS Fargate.
• We leverage multiple AWS-native components, such as S3, CloudFront, Lambda, Kinesis, and SQS.
• Our inference backend is written in Python (PyTorch, TorchScript) and is deployed across multiple clusters/cloud providers.
• We use Kubernetes for container orchestration, and k8s-native components such as Flyte, Kueue, and Kyverno for efficient job orchestration.
• We invest in Prometheus and Grafana for monitoring, and Terraform to manage our infrastructure.

Qualifications

• 3+ years of industry experience building production APIs.
• Strong TypeScript experience, so you can jump in and be productive immediately.
• Experience owning systems end-to-end: infrastructure, monitoring, logging, metrics, incident response.
• Understanding of API design patterns, REST principles, and async workflows.
• Experience with relational databases (Postgres preferred) and query optimization.
• Experience architecting production-ready systems at scale using cloud primitives from AWS, GCP, or Azure.
• Ability to rapidly prototype solutions and iterate on them with tight product deadlines.
• Humility and open-mindedness; we love to learn from one another.

Requirements

• Own the full API lifecycle from design and implementation to monitoring, optimization, and documentation for both public and internal APIs.
• Design and implement async workflows for task orchestration, content moderation, prompt enhancement, and post-processing pipelines.
• Optimize database queries and improve performance for a high-traffic Postgres database.
• Build rate limiting, fraud detection, and credit management systems.
• Implement comprehensive API security, rate limiting, authentication, and monitoring systems to ensure reliability at scale.
• Improve the public API developer experience with better documentation, SDKs, and tooling.
• Improve the performance, reliability, and code quality of our codebases.
