The role : Tech Lead, Software Engineer We're looking for a hands-on Tech Lead, Software Engineer to own and build the platforms that power how our company operates. You'll evolve existing production systems, develop new applications from the ground up, and set the technical direction for solutions spanning workflow automation, integrations, identity, and operational data. This is a builder's role. You'll make architectural decisions, design data models and APIs, write code, and ship production features yourself. You'll also use AI coding tools like Claude Code, Cursor, and GitHub Copilot as part of your daily workflow to accelerate development and delivery. You'll have the autonomy to identify problems, decide what to build, and turn business needs into reliable software that teams across the company use every day. Role responsibilities : Platform Ownership • Take technical ownership of our internal automation platforms end-to-end — architecture, data model, background sync/scheduling, and roadmap. • Design and ship full-stack features: backend services, role-based access control, approval workflows, and frontend UI. • Maintain and extend integrations with the external systems these platforms depend on — SaaS tools, cloud infrastructure, and internal directory/identity services. New System Development • Design and build new operational systems from the ground up in response to emerging business needs, including systems of record for tracking assets and entitlements, and dashboards that give teams visibility into usage, cost, and status. • Grow existing tooling in these areas from functional-but-narrow into fuller self-service products. SG&A & Cross-Functional Automation • Partner with IT, HR, and Finance-adjacent stakeholders to automate SG&A workflows — onboarding/offboarding, approval routing, audit logging, and access reviews — while those teams continue to own the underlying policy. • Build identity and access integrations (SSO/OAuth2) and RBAC models that satisfy audit requirements without slowing teams down. Engineering Practices & AI-Assisted Delivery • Own database schema evolution and maintain automated test coverage as the codebase and its scope grow. • Use AI coding platforms as a daily force multiplier for scaffolding, testing, and delivery speed. • Set and enforce engineering standards (separation of concerns, commit discipline, logging) as the codebase scales beyond a single owner. What we're looking for • BS/MS in Computer Science with 7+ years of professional software engineering experience. • Demonstrated ownership of a production web application end-to-end: backend (Python; FastAPI or similar), relational database design (PostgreSQL, SQL, schema migrations), and frontend work. • Experience integrating with enterprise SaaS APIs (e.g. Atlassian suite, Microsoft 365, GitHub/Bitbucket) and cloud infrastructure APIs (compute/storage, job schedulers). • Working knowledge of identity and access management — RBAC, SSO/OAuth2, and group provisioning via a directory service (LDAP or equivalent). • Experience designing systems of record or inventory/asset-tracking tools, and the dashboards that surface their data to different audiences. • Exposure to lic
