THE OPPORTUNITY

We are seeking a Staff Software Engineer to be the engineering anchor of our next-generation platform for home-improvement contractors: the system a contracting business runs on, end to end. This is a hands-on senior role on a greenfield TypeScript monorepo: an Express and PostgreSQL API on MikroORM, a React and Vite frontend, and a set of domain packages. You will own significant components of the platform, own its architecture and technical direction alongside product leadership, and be the engineer the team looks to for how it builds.

This is a build-first role with a leadership dimension. You will write production code every day and own the design of the areas you work in, and you will also raise the technical bar for the whole team: owning the architecture of the platform, aligning with the Product Lead on sequencing and delivery, and lifting the engineers around you through review, pairing, and clear standards. It is a technical-leadership track (not a people-management role); the intent is for the right person to grow into the technical lead of the platform’s engineering team as it scales.

RESPONSIBILITIES

Technical Leadership

• 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

Engineering and Architecture

• 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

Application Development

• 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)

AI-Native Engineering

• 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.
• Set the standard for where to trust agents, where to keep a human in the loop, and how to hold quality high while moving at agent speed

Platform Awareness

• Collaborate with platform engineering on deployment architecture and containerized services.
• Understand the CI/CD pipeline well enough to troubleshoot application-layer issues.
• Participate in infrastructure design reviews (AWS, infrastructure-as-code).
• Contribute to observability strategy and application-level instrumentation

Team and Mentorship

• Level up the engineers around you through code review, pairing, and design discussions.
• Raise the technical bar and help build a high-performing engineering team.
• Translate business requirements into technical plans and well-scoped deliverables.
• Collaborate closely across product, engineering, and infrastructure

REQUIRED SKILLS

• 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. This is a hard requirement, and we will ask you to show us how you work

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.
