Since 1999, we've combined innovative technology with high-quality, US-based client care. Our culture is built on collaboration, continuous learning, and a commitment to excellence, ensuring our team members feel valued, supported, and empowered. Role Summary Why this role matters AccuSourceHR is hiring a senior engineer to take ownership of a mature, customer facing .NET enterprise platform with multiple modules and complex integrations. You will work with two remote engineers for structured knowledge transfer over about 6 months, then own the platform end to end. You will ship customer driven improvements, modernize toward current .NET, build key integrations including background screening and payroll, and raise the quality bar through automation and strong production discipline. Your work will directly impact platform stability, release speed, and customer trust. What you will own 1) Knowledge transfer to full ownership (first 6 months) Run structured knowledge transfer covering architecture, module boundaries, data model, integrations, release process, known failure modes, and operational history Produce durable assets: architecture diagrams, runbooks, ADRs, onboarding guides, module maps, and a platform map that new engineers can use Build your own working model by reading, running, debugging, and documenting the system so ownership never depends on any single person By the end of the handoff period, operate, troubleshoot, and ship changes independently across the platform 2) Customer driven improvements and platform stewardship Own bug triage and prioritization and ship fixes and small enhancements based on customer feedback and usage signals Reduce recurring issues by addressing root causes and adding regression coverage, not just patching symptoms Update branding and customer facing surfaces to align with AccuSourceHR including

AccuSourceHR background screening workflows including APIs, identity patterns, data flows, and user journeys Lead a payroll provider integration end to end including data contracts, mapping, error handling, retries, reconciliation, auditability, and observability Improve integration reliability with versioning, idempotency, rate limits, clear failure modes, and production visibility 4)

for critical flows Add CI quality gates so tests and checks run by default and releases are safe and repeatable Own production outcomes: troubleshoot issues end to end, improve logging and traces, write post incident notes, and implement permanent fixes 6) AI assisted development (secure and practical) Use AI tools daily to accelerate understanding, refactoring, documentation, test scaffolding, impact analysis, and debugging while keeping code and data private Define team practices for safe AI usage including redaction, internal code search or RAG patterns, review expectations, and measurable productivity improvements without IP leakage Use AI to produce better artifacts, for example module summaries, dependency maps, migration checklists, and test plans, while keeping humans accountable for correctness 7) Technical leadership and team growth Work independently by identifying risks, proposing solutions, and executing without detailed task lists Mentor and onboard future
