The AI Lab is composed of leading software and AI engineers, designing agentic-AI solutions ahead of the market. Our group builds and operationalizes the AI systems that power Accordion’s consulting capabilities, from agentic architectures and RAG pipelines to evaluation frameworks and production observability.

The Lab works closely with practice leaders to translate research findings into scalable, reliable tools that advance Accordion’s AI-driven value creation work for PE clients and their portfolio companies.

This posting covers three levels:
Staff Software Engineer, Senior Staff Software Engineer, and Executive Director, Software Engineering. We’re hiring the engineers who set the technical bar for how AI Lab builds — not just shipping an agentic system end-to-end, but deciding how every pod builds agentic systems: which orchestration patterns get reused, what “production-ready” means for an eval framework, and when a client problem needs a genuinely new architecture rather than another RAG pipeline.

You’ll operate at the intersection of hands-on engineering and technical leadership. Expect to spend real time in the code and real time in the room with CFOs and PE operators defending the call you made. This is a highly technical role at every level in this posting — technical depth is the qualifying bar, not a management-track substitute for it. You will be expected to ship fast, defend your decisions, and continuously raise the bar on what AI-assisted delivery looks like.

• Architect and ship the hardest agentic systems in the portfolio — multi-agent orchestration, RAG pipelines, and evaluation infrastructure for PE-backed portfolio companies
• Set technical standards and reusable patterns (orchestration frameworks, structured-output contracts, eval methodology) that other pods adopt across client engagements
• Own build-vs-buy and architecture trade-off decisions, and defend them to technical and non-technical audiences, including CFOs and PE operators
• Build and evolve the observability and evaluation infrastructure that keeps production AI quality measurable firm-wide, not just pod-by-pod
• Mentor and technically develop other engineers through architecture reviews, paired work on hard LLM problems, and code review
• Travel to client sites as needed to scope, present, and stand behind the work
• At the Senior Staff /…
