Requirements

Bachelor's degree in Computer Science, Software Engineering, or equivalent professional experience
5+ years of professional software development in a production environment
Strong C#/.NET
Solid SQL — read stored procedures, write good queries, and recognize performance problems at scale
Comfortable with Azure and cloud environments
API design, background services, and multi-system integration development
Able to debug across system boundaries, not just the code immediately in front of you
Good testing instincts for real-world edge cases and failure modes
Already using AI development tools effectively as a genuine part of daily work

Nice To Haves

Experience within distribution, supply chain, e-commerce, or similarly complex operational environments preferred
Hands-on experience integrating against LLM APIs (OpenAI, Anthropic, or similar) — rate limits, error handling, cost management, and applying them to real business problems rather than just experimentation
Experience with Epicor Prophet21 (P21) or a similarly complex distribution/wholesale ERP
Familiarity with Akeneo, Algolia, Salesforce, Canals.ai, or similar platforms
Experience building AI or automation workflows — document processing, workflow orchestration, or intelligent routing
EDI or supply chain integration experience
When something breaks: investigate it, prove what's happening, propose a fix that preserves intended behavior, and escalate only if it's architectural or business-related — not every problem needs to come back up
Takes well-framed problems, asks useful questions, and delivers working software rather than waiting for a complete specification
Comfortable making technical decisions independently, and calibrated about when a decision has crossed into territory that needs a conversation
Embody Banner Solutions' values of Courtesy, Respect, Quality, Professionalism, and Discipline
Genuinely collaborative — works well with the Systems Architect, cross-functional teams, and business stakeholders
Balance speed and quality — moves fast without creating problems that slow the team down later
Comfortable across both backend and web code — not helpless when something crosses a layer

Responsibilities

Build and maintain integration workflows connecting core platforms including P21 (ERP), Salesforce, Akeneo (PIM), Algolia, and Canals.ai
Design and implement APIs, background jobs, and automation pipelines that handle real transactional volume reliably
Debug across system boundaries — trace problems through multiple systems rather than stopping at the code immediately in front of you
Ensure integrations perform well, fail gracefully, and are maintainable by the team over time
Write code with good testing instincts: how do we prove this works, what happens when it fails, and what edge cases are we missing?
Build integrations against LLM APIs — OpenAI, Anthropic, or similar — to power Banner's automation initiatives in areas including order processing, customer communications, and purchasing operations
Apply AI development tools fluently as part of daily work: to move faster, explore approaches, and think more thoroughly — while applying independent engineering judgment to what the tools produce
Contribute to automation workflows that reduce manual labor and improve operational consistency across Banner's distribution business
Receive architectural direction from the Systems Architect and independently drive significant features or integrations through to completion
When something unexpected surfaces: investigate it, determine root cause, make the call if it's yours to make, and bring a clear recommendation back if it's architectural or business-related
Make normal technical decisions without asking permission — and recognize when a decision has crossed into territory that needs a conversation
Take business problems that aren't perfectly specified and turn them into working software, asking the questions that matter rather than waiting for a complete ticket
