Responsibilities

Build and ship features across the NEXiA platform — pharmacy workflows, hardware integration, operator interfaces — working within and improving the existing codebase
Own features end-to-end: understand the domain context, design the approach, implement across the legacy/modern boundary, test, and support through deployment
Work across the full stack — VB.NET backend, .NET Core services where they exist, front-end interfaces, SQL Server data access, and hardware integration layers
Write code that moves the codebase forward: when you touch a module, leave it more testable, more maintainable, and closer to modern patterns than you found it
Navigate and improve a VB.NET codebase that has evolved through multiple technology generations
Identify opportunities to migrate legacy components to modern .NET/C# — not as a separate initiative, but as part of feature delivery and defect resolution
Build and maintain the seams between legacy VB.NET code and modern .NET components; manage the coexistence practically
Apply pragmatic judgment about what to modernize now versus what to isolate and defer — not everything needs to be rewritten, but nothing should be left unexaminable
Write meaningful tests for the existing codebase, introduce test seams, extract interfaces, break dependencies as needed
Build automated validation that works across the legacy/modern boundary, catching regressions before they reach customer environments
Troubleshoot and debug across the full stack(including 32-bit VB.NET components)with a systematic approach; production issues in pharmacy automation have real operational impact
Improve test infrastructure: create the test coverage that doesn’t exist today so the team can change code with confidence
Operate as an orchestrator of AI-assisted engineering workflows, not just a developer with an autocomplete plugin. The practical workflow: directAI agents to comprehend a legacy module, generate characterization tests that capture actual behavior, propose migration approaches, review and validate output before shipping. You own the judgment; the AI multiplies your throughput
Apply AI tooling to the hardest parts of legacy work: mapping undocumented business logic across VB.NET modules, generating test suites for legacy code, identifying coupling patterns and migration risks across a large codebase, and scaffolding modern .NET replacements
Maintain verification discipline — in a codebase where behavior is undocumented, AI tools will confidently generate plausible-but-wrong characterizations. Knowing when to trust and when to verify is as important as knowing how to prompt
Develop and share effective AI workflows with the team; this team’s velocity depends on tooling leverage, not just headcount. What you learn about applying agentic tools to legacy modernization makes everyone faster
Work alongside the engineers driving architectural decomposition (Platform Modernization, Database Modernization) to ensure feature work aligns with the broader migration strategy
Participate in design discussions with honesty about what the legacy codebase can and can’t support without deeper changes
Mentor other engineers on navigating legacy code, introducing tests into untested systems, and practical migration patterns
Communicate trade-offs clearly to product and leadership: what you can build cleanly now, what requires legacy improvement first, and what the cost of deferring improvement looks like

Required

6+ years of professional software development experience, with significant time spent in legacy or brownfield codebases (not exclusively greenfield)
Strong proficiency in .NET — modern .NET/C# preferred, but demonstrated ability to work productively in older .NET technologies (VB.NET, .NET Framework, WinForms)
Experience improving codebases you inherited: introducing tests where none existed, refactoring without rewriting, migrating incrementally between technology generations
Hands-on experience building and consuming APIs, with working knowledge of service integration patterns
Solid SQL Server skills — querying, performance analysis, schema understanding — in a codebase where the database is deeply coupled to application logic
Pragmatic engineering judgment: knowing when to improve, when to isolate, and when to leave something alone
Active engagement with AI-assisted development tools in your daily workflow — not autocomplete-level usage, but using AI for code comprehension, test generation, refactoring, or migration work. Existing agentic workflow experience (Claude Code, Cursor, etc.) is ideal; demonstrated rapid adoption and concrete experimentation is acceptable
Comfort working in a regulated, on-prem environment where deployments are customer-specific and rollbacks are expensive

Preferred

Direct experience migrating VB.NET or VB6 applications to modern .NET/C#
Experience with pharmacy automation, healthcare, or other regulated environments where software controls physical processes
Familiarity with DDD concepts — bounded contexts, aggregates, domain events — even at a working level
Experience with CI/CD pipelines (Azure DevOps, GitHub Actions) and containerization
Experience with front-end frameworks (Angular, React, Blazor)
Exposure to event-driven or message-based architectures

Benefits

Generous time off policy that allows you to put your family first
Opportunity to work on the cutting edge of pharmacy automation in a high growth tech company
Competitive benefits, salary, and talent development opportunities
Commitment to professional development and working for a company where your voice is heard
