Lead Platform Engineer

Job Summary

We're looking for a Lead Platform Engineer to become the technical backbone of FocusPoint's day-to-day platform operations. This is a hands-on senior IC role — you'll own the platform the way our founding engineer does today, with a clear growth path toward leading a small engineering team as the company scales.

You'll be the #2 technical voice on the platform: deep in the code, owning architecture decisions, keeping multi-region infrastructure healthy, and driving the work that keeps 500+ clients running without interruption.

About FocusPoint

FocusPoint is a B2B e-commerce SaaS platform serving 500+ enterprise client organizations across North America and Europe. Built on a customized .NET Core foundation with deep SAP integration, multi-tenant architecture, and complex checkout and business partner management workflows — FocusPoint is serious commerce infrastructure for serious businesses, and we're growing.

Duties

• Platform reliability — monitoring, performance optimization, and proactive resolution of issues across a multi-tenant SQL Server and Azure environment
• Core feature development — building and shipping complex e-commerce workflows including checkout, quoting, pricing, inventory, and business partner management
• SAP integration — maintaining and extending SAP Business Partner sync, order processing pipelines, and address management workflows
• Infrastructure — Azure SQL Failover Groups, Redis / MemoryCache management, and multi-region deployment across US and EU
• Search & indexing — Solr configuration, concurrency, and performance tuning
• Database optimization — query tuning, index strategy, bulk operations, and audit instrumentation
• Client customizations — preserving tenant-specific overrides while consolidating and evolving the core platform codebase
• Code quality & documentation — raising the bar as we grow

Experience

• 7+ years of professional software development experience
• Strong .NET Core / C# — you write clean, maintainable, production-grade code
• SQL Server — not just queries, but indexes, execution plans, and schema design
• Experience with multi-tenant SaaS architecture
• Azure cloud familiarity — deployments, storage, failover, caching
• Ability to own a problem end-to-end without heavy direction
• LinqToDB or similar micro-ORM (we don't use Entity Framework)
• FluentMigrator or similar database migration tooling
• Kendo UI or enterprise component library experience
• B2B / enterprise commerce domain knowledge

Growth Path

This role is designed to evolve. As FocusPoint grows its engineering team, this person is the natural candidate to step into an Engineering Manager role — owning hiring, team processes, and technical direction while staying close to the code. If you want to grow into leadership without leaving the technical side behind, this is that seat.
