About the role
We are looking for a Principal Software Engineer to join a small, highly experienced Epicor Labs team that transforms innovative AI concepts into enterprise-grade products trusted by enterprise customers.
This is a hands-on engineering role, not a management position. You will design and build, set the technical bar for production quality, and provide the architectural judgement needed to take AI-driven products from promising prototype to something enterprise customers can trust with their business data.
What You'll Do
As a Principal Engineer, you'll play a key role in designing and delivering the next generation of AI capabilities across Epicor's ERP portfolio.

What You'll Do
As a Principal Engineer, you'll play a key role in designing and delivering the next generation of AI capabilities across Epicor's ERP portfolio.
- PoCs and MVPs in AI transformation projects inside enterprise ERP software - rapid exploration of new capabilities, with the engineering discipline to evolve the successful ones into production-grade services.
- Cloud platform services - designing and building the services, APIs, and data layers that new AI capabilities run on, integrating with large, established ERP products.
- Production readiness - bringing R&D output up to enterprise standard: reliability, observability, security, multi-tenancy, and safe failure behaviour.
- AI engineering - integrating LLMs and agentic patterns into business software responsibly: guardrails, permissions, auditability, and designing for the probabilistic nature of AI components acting on real business data.
- Raising the bar - architectural review across the team's workstreams, mentoring engineers at all levels, and turning good judgement into standards and automation rather than tribal knowledge.
- Principal-level engineering depth in C#/.NET and/or Python, with cloud platforms (Azure preferred), and a strong record of designing and shipping production services. Our systems span both stacks - strength in one with working fluency in the other is the expectation.
- Hands-on exposure to AI-assisted engineering - building with LLM APIs, agentic coding tools, and prompt-driven workflows, and a grounded view of where they help and where they don't.
- Experience taking early-stage products (PoC/MVP) to production, ideally in enterprise software.
- AWS experience.
- Complex business-domain experience - ERP, e-commerce, finance, logistics - and an appreciation of the cost of getting business data wrong.
- Security instincts: least privilege, tenancy isolation, trust boundaries.
Within your first 3 months, you'll:
- Deliver production-quality code
- Lead the design of major platform capabilities
- Become a trusted technical leader and architectural reference point
- Mentor engineers and help raise engineering standards across Epicor Labs
Epicor Labs is the innovation engine behind AI transformation across Epicor's ERP portfolio.
Our team explores new ideas, rapidly prototypes solutions, and turns successful concepts into production-ready capabilities before handing them over to product engineering teams.
