Job Description

We're hiring a hands-on Senior Software Engineer to help build and scale our AI Platform.

This is a senior execution-focused engineering role for someone who thrives in ambiguity, moves quickly from concept to proof-of-value, and turns AI capabilities into reliable, production-grade systems. It's about building, shipping, and owning impactful systems.

What You'll Work On

  • Cloud-native services deployed on AWS (EKS/ECS, Serverless)
  • Orchestrated AI workflows and agents
  • Human-in-the-loop approval systems
  • Data pipelines and ingestion workflows
  • LLM and OCR integrations for document understanding and content generation
  • React-based UI supporting operational workflows
  • Search and knowledge systems (Postgres, Redis, OpenSearch, S3)

Key Responsibilities

  • Own complex AI-driven workflows from concept to production
  • Translate ambiguous ideas into scalable system designs
  • Build fast proofs-of-concept and iterate into production systems
  • Integrate LLMs, OCR, and external AI APIs into reliable pipelines
  • Build and optimize data models and async event-driven systems
  • Mentor engineers and raise the technical bar
  • Measure performance across accuracy, latency, cost, and adoption
  • Debug and resolve production issues with ownership and clarity

Desired Skills and Experience

  • 10+ years of software engineering experience with strong TypeScript and/or Python expertise
  • Experience in building distributed, production-grade systems on AWS and Kubernetes
  • Strong understanding of REST APIs, async/event-driven architectures, and CI/CD practices
  • Solid SQL skills (Postgres preferred) and experience with data modeling
  • Experience building AI-powered systems using LLMs, OCR, and orchestration/workflow frameworks
  • Familiarity with search/indexing systems and frontend development (React)
