Job description
Banner Solutions is a premier national wholesale distributor specializing in commercial door hardware, access control systems, and security hardware products across CSI Divisions 8, 10, and 28. As a leader in the commercial door and security hardware industry, we represent more than 260 manufacturers and deliver industry-leading service with a 98%+ same-day ship rate.
Our customers include Contract Hardware Dealers, Glass & Glazing Dealers, Building Material Suppliers, Electronic Access Integrators, Locksmiths, Institutional End Users, e-tailers, and retailers nationwide. Through our nationwide distribution network, deep product expertise, and strong manufacturer partnerships, we help customers secure and complete buildings across the country.
Banner Solutions is built on a culture of ownership, collaboration, and accountability. Our team members are empowered to make an impact while delivering the expertise, service, and reliability our customers depend on.
CORE RESPONSIBILITIES
The Senior Software Engineer — .NET / Integration / Automation will serve as a hands-on technical contributor within Banner Solutions' Chief Digital Officer organization, working directly with the Systems Architect to build and maintain the integrations, automation workflows, and AI-powered systems that run Banner's operations.
Reporting directly to the Systems Architect , this role is part of the CDO organization and operates across multiple platforms and business functions. The Senior Software Engineer will take architectural direction and independently carry substantial features or integrations through to completion.
This is not a ticket-driven role. The ideal candidate takes a well-framed problem, asks the right questions, makes the technical decisions that are theirs to make, and delivers working software — pulling the Systems Architect back in at the decision points that actually matter.
Integration & Systems Development
Build and maintain integration workflows connecting core platforms including P21 (ERP), Salesforce, Akeneo (PIM), Algolia, and Canals.ai — "make these three systems work together reliably" is a common problem here
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?
AI-Augmented Development
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
Understand the specific failure mode of AI-assisted development: the risk isn't code that breaks loudly on deploy. It's a confident answer with a wrong number that ships cleanly and nobody questions for six months. We need someone who treats AI output the way good engineers treat untested code — verify it, question it, and own the result.
Technical Ownership & Judgment
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
Required
Bachelor's degree in Computer Science, Software Engineering, or equivalent professional experience
5+ years of professional software development in a production environment
Experience within distribution, supply chain, e-commerce, or similarly complex operational environments preferred
Strong C#/.NET — this is the core of what Banner builds
Solid SQL — read stored procedures, write good queries, and recognize performance problems at scale
Comfortable with Azure and cloud environments — Banner is actively moving workloads to the cloud
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
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. Willingness to learn P21 at the operational level — not just how the API works, but how buyers, order processors, and customer service reps actually use it. Prior P21 experience is a bonus; the instinct to go deep on a domain system until you understand it the way the business does is the requirement.
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
We'd rather hire a strong engineer who can learn our systems than narrow the pool for someone who happens to already know our exact stack.
Cultural Fit & Attributes
When something breaks: investigate it, prove what's happening, propose a fix that preserves intended behavior, and elevate 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
SUCCESS METRICS - FIRST 12 MONTHS
Success will be measured by the ability to take ownership of substantial work and deliver it independently, with technical judgment, engineering quality, and escalation calibration that earns the confidence of the Systems Architect.
The Senior Software Engineer will help ensure:
At least one significant integration or automation feature is delivered with minimal implementation-level direction
Problems are investigated and diagnosed rather than surfaced — escalations come with root cause analysis and a proposed solution
AI development tools are a measurable part of how this engineer works, accelerating delivery without compromising quality
The Systems Architect is confident handing a meaningful piece of the system to this engineer and trusting it will come back done
Technical decisions are made at the right level — autonomously when appropriate, escalated clearly when architectural or business-related
The team's codebase is left more maintainable, better tested, and more reliable as a result of this engineer's contributions
