Staff Software Engineer, Contractor Platform

About the role

We are seeking a Staff Software Engineer to be the engineering anchor of our next-generation platform for home-improvement contractors. This is a hands-on senior role on a greenfield TypeScript monorepo, serving as the technical leader for the platform.

Responsibilities

• Serve as the engineering anchor for the platform: the person the team looks to for technical direction, patterns, and quality.
• Own the architecture and long-range technical strategy for the platform, and align with the Product Lead on scoping, sequencing, and delivery.
• Set and uphold the engineering standards for the squad: coding standards, testing strategy, review practices, and the definition of done.
• Grow into the technical lead of the platform’s engineering team as it scales; drive technical planning and unblock the engineers around you.
• Own the design and delivery of significant components and domain areas of the platform.
• Contribute to the architecture and technical direction of the codebase alongside the team.
• Help shape and uphold the patterns that govern the codebase: strict typing, factory and dependency-injection patterns, and clean package boundaries.
• Drive API design for the areas you own, and align on shared contracts across the platform.
• Author and contribute to design documents and ADRs for significant changes.
• Contribute production code across the stack in TypeScript: Express and MikroORM on the backend, React and MUI on the frontend.
• Design data models, migrations, and schema-evolution strategies on PostgreSQL.
• Architect integration patterns for external platforms and third-party APIs.
• Design frontend state management and data-intensive UI patterns with TanStack Query and MUI.
• Optimize application performance across the full stack (queues, caching, background workers).
• Delegate whole features to autonomous agents, work across several in parallel, and review and direct their output rather than hand-typing most of the code.
• Build and improve what makes agentic development work here: the skills architecture, MCP integrations, prompts, specs, and guardrails that let agents ship safely.
• Codify context and patterns so both engineers and agents move faster, and keep raising the ceiling for what can be delegated to AI.
• Translate business requirements into technical plans and well-scoped deliverables.
• Collaborate closely across product, engineering, and infrastructure teams.

Requirements

• Minimum of Associate’s Degree, Bachelor’s Degree preferred.
• 8+ years of professional software engineering experience.
• Deep expertise in TypeScript across the stack: Node and modern React, not just the API surface.
• Strong experience with a backend framework and ORM (Express, MikroORM, or comparable), plus relational database design, query optimization, and migration management.
• Proven track record of designing and evolving well-architected systems and owning complex components end to end.
• A track record of shipping: merged, working software in front of customers is your unit of progress, and you can point to what you shipped recently.
• A track record of setting technical direction for a team and mentoring the engineers around you; someone others look to as the technical anchor.
• Familiarity with RESTful API design, authentication flows, and multi-tenant SaaS patterns.
• Experience with containerized deployments (Docker, ECS, or Kubernetes).
• AI is central to how you personally ship, and you already work at a high level of autonomy with it: you hand whole tasks to agents, coordinate several at once, and build the workflows that make them effective.

Preferred Skills

• Experience as a tech lead or technical anchor on a high-performing engineering team.
• Experience leading large-scale platform migrations: merging separate applications, consolidating data models, or unifying multiple systems onto one platform.
• Experience with home-services, field-service, or contractor SaaS domains.
• Deep PostgreSQL or MikroORM experience.
• Background with RBAC and permission systems.
• Experience with observability platforms and distributed tracing.
• A track record of building developer tooling or AI workflows that made a team measurably faster.
