Responsibilities

  • Rapidly prototype AI agents and guided workflows that solve concrete customer problems; ship thin slices, instrument, and iterate with real usage.
  • Design and implement cloud-native backend services that orchestrate prompts, tools, retrieval, and automations; own the path from POC to production.
  • Build robust retrieval for LLMs (search/vector pipelines, context assembly, tool selection) in partnership with data engineering.
  • Establish evaluation loops: offline/online tests, golden sets, regression checks, and human-in-the-loop review to measurably improve quality and safety.
  • Contribute to developer experience: reusable agents/tools, SDKs, templates, and internal documentation that speed up future builds.
  • Collaborate with customers and internal stakeholders to frame problems, define success metrics, and translate insights into productizable solutions.
  • Lead design discussions and code reviews; mentor teammates and raise the quality bar while keeping momentum high.
  • 4-8+ years as a software/AI engineer, including shipping 0→1 products or features in startup-like environments.
  • Strong in Python (and comfortable with TypeScript); able to build production services and integrate with external systems/APIs.
  • Proven experience taking LLM/agent systems to production (tool use, function calling, planning/exec, retrieval-augmented generation).
  • Hands-on with evaluation (offline/online), prompt engineering, tracing, and observability for AI systems.
  • Familiarity with vector databases/search, embeddings, and context/retrieval patterns; pragmatism about when/what to index.
  • Solid backend fundamentals (services, queues, data models, CI/CD, cloud) and a bias to automate what you repeat.
  • Excellent communication and product sense-able to turn fuzzy business problems into clear technical plans and measurable outcomes.
  • Fast mover: comfort with ambiguity, crisp prioritization, and the judgment to ship small, safe increments quickly.
  • Nice-to-have: open-source contributions, hackathon wins, or a portfolio of shipped side projects; experience at both an early-stage startup and a larger-scale system.
  • What We're Offering
  • Salary Range: $90,000 to $100,000 plus bonus
  • Flexible paid time off, including sick and holiday
  • Medical, dental, & vision insurance
  • 401K with Company contribution
  • Flexible spending accounts
  • Life insurance and disability benefits
  • Tuition assistance
  • Community involvement and volunteering events
  • All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or status as a protected veteran. VEVRAA Federal Contractor, Equal Opportunity Employer

Additional Information

We are seeking an AI Engineer with a builder's mindset to bring cutting-edge AI agents and workflows into production for IFS Nexus Black. You'll turn ambiguous customer problems into working prototypes in days/weeks, iterate in the field, and scale the winners into reliable products. You will work across the stack-prompting, tools, retrieval, evaluation, guardrails, and backend services-collaborating closely with product, design, and data engineering. Expect high autonomy, direct exposure to customers, and a fast loop from idea → demo → production.
