Senior Backend API Engineer - Cloud & AI Systems

Location: Remote (North America & Europe)

Compensation: $250,000 - $300,000 base salary + potential equity package

We are seeking a Senior Backend API Engineer to join a team building high-performance, cloud-native systems that support large-scale data processing and AI-powered applications. This role is ideal for engineers who enjoy solving complex technical problems, optimizing performance, and delivering production-ready backend services at scale.

Our engineering team works across multiple domains, including building scalable APIs, orchestrating workloads in the cloud, and deploying machine learning models and data pipelines to production.

Technical Stack

  • API layer: TypeScript or comparable backend language, deployed in containerized environments (ECS, Fargate, or similar)
  • Cloud infrastructure: AWS or GCP services including S3, CloudFront, Lambda, Kinesis, and SQS
  • ML / inference backend: Python (PyTorch, TorchScript) deployed across multiple clusters and cloud providers
  • Container orchestration: Kubernetes, including k8s-native orchestration tools
  • Monitoring & observability: Prometheus, Grafana, or equivalent
  • Infrastructure management: Terraform or similar infrastructure-as-code tools

Responsibilities

  • Design, implement, and maintain public and internal APIs supporting high-throughput backend systems
  • Take ownership of the full API lifecycle, from design and implementation to monitoring, optimization, and documentation
  • Implement security, authentication, rate limiting, and observability to ensure APIs are reliable at scale
  • Optimize performance, reliability, and maintainability of backend services
  • Collaborate with cross-functional teams to deploy AI-powered systems and data pipelines
  • Rapidly prototype, benchmark, and iterate on solutions under evolving technical requirements

Must have skills

  • 4+ years of experience in a backend-focused software engineering role with Typescript
  • Experience with PostgreSQL (query optimization, indexing, schema design)
  • Proven ability to architect production-ready systems at scale using cloud services
  • Experience with containerized services and orchestration (ECS, Kubernetes, or equivalent)
  • Strong problem-solving, collaboration, and communication skills
  • Ability to work in a fast-paced, high-ownership environment

Nice to have skills

  • Experience deploying machine learning or AI models in production
  • Background in high-throughput, low-latency, or distributed systems
  • Familiarity with observability tooling (Prometheus, Grafana)
  • Experience with CI/CD pipelines and infrastructure-as-code

Why This Role

  • Work on technically challenging backend systems supporting large-scale AI and data applications
  • Take ownership of API design, performance, and reliability
  • Collaborate with a skilled, cross-functional team tackling complex infrastructure and ML deployment challenges
  • Influence the architecture and scaling of critical backend systems
