Facility Grid•Waltham, MA

2d•Hybrid

About The Position

We are seeking a Staff Engineer to serve as the application architect for FacilityGrid’s SaaS platform. This role owns the technical direction of our application layer — a PHP/Laravel backend, an Angular/TypeScript frontend, and supporting microservices — while maintaining working familiarity with the underlying cloud infrastructure and deployment platform. You will be the technical decision-maker for how our application systems evolve, ensuring architectural coherence across a growing codebase and team. FacilityGrid is an AI-first company. We expect every team member to actively leverage AI-based tooling to work faster and solve problems more effectively. Candidates who already incorporate AI into their development workflow will stand out. This is a hands-on leadership role. You will write code, review designs, mentor engineers, and drive the technical strategy that enables FacilityGrid to scale its construction and facilities management platform.

Requirements

8+ years of professional software engineering experience
Deep expertise in PHP/Laravel — you understand the framework internals, not just the API surface
Strong experience with Angular or comparable TypeScript SPA frameworks
Proven track record of designing and evolving application architectures at scale across multiple teams
Experience with relational database design, query optimization, and migration management
Familiarity with RESTful API design, OAuth2 authentication flows, and multi-tenant SaaS patterns
Experience with containerized deployments (Docker, ECS, or Kubernetes)
Strong written communication — you can author clear technical design documents and ADRs
Willingness to use AI-based development tools as a core part of your workflow

Nice To Haves

Experience with construction, facilities management, or field-service SaaS domains
Familiarity with construction management platform integrations (e.g., Procore)
Experience with GitOps workflows and infrastructure-as-code tooling
Background with RBAC systems and enterprise SSO/SCIM provisioning
Experience with observability platforms and distributed tracing
Experience leading large-scale platform migrations — merging separate applications, consolidating data models, or unifying multiple systems onto a single platform

Responsibilities

Own the application architecture across backend, frontend, and service layers
Evolve and maintain the layered patterns and conventions that govern the codebase
Drive API design decisions across versioned REST endpoints
Author and maintain Technical Design Documents for significant system changes

Establish and enforce coding standards, testing strategies, and review practices
Contribute production code in PHP/Laravel and TypeScript/Angular
Design data models, migrations, and schema evolution strategies

Design frontend state management and data-intensive UI patterns
Optimize application performance across the full stack (caching, queues, CDN)
Collaborate with platform engineering on deployment architecture and container orchestration
Understand containerized build and CI/CD pipelines well enough to troubleshoot application-layer issues
Participate in infrastructure design reviews involving GitOps workflows and infrastructure-as-code
Contribute to observability strategy and application-level instrumentation
Mentor mid-level and senior engineers through code review, pairing, and design discussions
Raise the technical bar across the engineering organization
Translate business requirements into technical roadmaps and decomposed deliverables
Bridge communication between product, engineering, and infrastructure teams
