Join a team building a comprehensive AI technology stack (focused on GenAI) that accelerates AI capabilities across hundreds of customer products. The platform integrates with major AI providers and enables scalable, production-ready AI solutions for professional users.

The team is divided into core development and product integration streams.

What You’ll Do

• Design and implement full-stack applications, AI agents, and platform components that enable rapid GenAI agent development, validation, and deployment
• Build developer tooling, CI/CD, and observability for safe, fast iteration (evals, canaries, rollout/rollback, cost and quality telemetry)
• Apply secure SDLC and privacy-by-design practices (threat modeling, least privilege)
• Collaborate with product, UX, and domain experts to deliver customer-focused solutions with measurable outcomes
• Apply current LLM patterns (RAG, retrieval, routing, tool-use, evals) to deliver measurable customer value — faster, more reliable AI systems; reduced time-to-decision; improved trust/safety metrics; and lower cost per query
• Lead by example and be heavily hands-on: drive architecture, mentor engineers, and take ownership of larger projects

What You Bring

• 8+ years of professional software engineering experience
• Strong full-stack development skills and cloud experience (AWS, Azure, or GCP)
• Expert in at least one, and proficient across the others:
  • AI agent development and evaluation
  • Backend development
  • Frontend development
  • Cloud services (AWS/Azure/GCP)
  • CI/CD and Infrastructure as Code
  • Site Reliability Engineering (SRE)
  • Quality engineering / testing strategy
  • Secure SDLC and privacy by design
• Proven track record delivering secure, reliable, cloud-native systems to production
• Excellent problem-solving, ownership, and cross-functional communication
• US Central Time overlap (9–11 AM CDT).

Nice to have

• Proven ability to deliver software products independently or as part of a small, fast-paced team
• Experience taking AI agents from concept to production, including safety evaluations, iterative testing (e.g., A/B testing), and continuous improvement
• Experience with LangChain, LangGraph, MCP; vector/RAG systems; OpenSearch
• Experience with traditional ML tasks such as training, deployment, and monitoring
• Understanding of how LLMs work, their failure modes, and techniques such as fine-tuning and model adaptation
• Familiarity with regulatory frameworks such as SOC 2, HIPAA, etc.

Nice to have – Upper-Intermediate
