Position Description: ServiceTrade empowers commercial service contractors in fire protection, HVAC, mechanical, electrical, and beyond to service smarter and scale faster. Our platform helps thousands of contractors maximize technician productivity, deliver digital-first customer experiences, and grow profitably. When skilled techs are hard to find and manual systems slow you down, ServiceTrade is how the best contractors pull ahead. Under the hood, that mission runs on a serious piece of engineering: a multi-tenant SaaS platform built on PHP, Doctrine, MySQL, MongoDB, and AWS, processing the real-time workflows that keep commercial service operations moving. It's battle-tested, revenue-generating, and architecturally complex. It's also ready for its next chapter. We're hiring a Staff Engineer to help write that chapter. You'll join a team that's investing in the long-term health of this platform: evolving the architecture, modernizing incrementally, improving reliability, leaning into AI acceleration tooling, and building the infrastructure to scale the next phase of growth, all without breaking what works for the thousands of contractors who depend on us every day. This is a hands-on technical leadership role. You'll own critical architectural decisions across backend and infrastructure, mentor engineers, and shape how we build software in this new world of agentic AI. If you've ever looked at a complex production system and thought "I know how to make this better, one piece at a time," this is the job. Why ServiceTrade: Real problems at real scale. Sharded MySQL, MongoDB read models, event-driven async processing, multi-tenant isolation: this isn't a CRUD app. You'll work on genuinely interesting distributed systems challenges with real customers depending on the outcome. Modernization with purpose. Our platform has years of production-hardened domain logic. The opportunity isn't to rewrite it, it's to evolve it. Incrementally migrate frameworks, extract services where it makes sense, adopt modern patterns, and improve developer experience, all while keeping the lights on for thousands of customers. This is the kind of work that separates good engineers from great ones. First-Class Tooling. You will be equipped with the latest AI-assisted tooling available to help you navigate, refactor, and modernize our complex codebase more efficiently. Influence without bureaucracy. This is a team where a staff engineer's voice carries real weight. You won't be writing RFCs that disappear into a committee. You'll propose a direction, build consensus, and ship it. Key Responsibilities and Activities: Architecture a history of coaching teams on how to balance test coverage with developer velocity while maintaining a 'zero-regression' mindset Deep experience with Doctrine ORM and ODM (entity mapping, repositories, query builder, hydration strategies, proxy generation, N+1 prevention, lazy/eager loading trade-offs) Strong production experience with MongoDB (document modeling, aggregation pipelines, ODM tooling) Extensive hands-on experience with AWS: CloudFormation/Terraform, EC2, RDS, S3, SQS, SES, Lambda, ElastiCache, VPC networking, IAM policies Strong experience designing and operating asynchronous processing systems (SQS or equivalent), including worker supervision, DLQ strategies, idempotency, backoff/jitter, and visibility-timeout management Production experience with Redis for caching, session management, and distributed locking Strong Docker and Docker Compose skills for development, CI, and packaging workflows Experience building and maintaining CI/CD pipelines (GitHub Actions preferred) Working knowledge of AWS services (EC2, RDS, S3, SQS, SES, Lambda, ElastiCache, VPC networking) sufficient to troubleshoot, contribute infrastructure-as-code changes, and collaborate effectively with SRE Demonstrated ability to lead technical initiatives, make architectural trade-offs, and influence without authority Excellent written and verbal communication skills; comfortable producing technical documentation and RFCs Nice to Have: Experience modernizing large PHP monoliths: incrementally migrating frameworks, extracting services, or evolving architecture while maintaining production stability Experience with CQRS and event-sourcing patterns Familiarity with Typesense, Elasticsearch, or similar search infrastructure Experience with Auth0 or other identity/SSO platforms and patterns Experience with configuration management (Puppet, Ansible) or infrastructure automation Familiarity with Kinesis, CloudWatch, or other AWS observability tooling Experience with static analysis tools (Psalm) and automated refactoring (Rector) Familiarity with frontend frameworks (React, Ember.js), enough to collaborate effectively with frontend engineers Experience with serverless patterns (AWS Lambda, SAM) Background in multi-tenant SaaS architecture and data isolation strategies A few things you want to know: What does ServiceTrade do?
