Optimy.ai is an AI-powered lead conversion platform used by 322+ dealerships across North America. When a customer texts, calls, or submits a lead — our AI responds instantly. Speed wins in this industry.

We’re growing fast in a $500M+ market. Our engineering team is small, moves quickly, and builds software differently than anywhere you’ve worked before.

We need a Senior Full Stack Developer who can write production code, make architectural decisions, and eventually lead a team.

We’re migrating from a PHP monolith to a modern, AI-first SaaS platform — and we need someone who can help shape what that looks like. You’ll own architectural decisions, ship production code, review PRs, mentor junior developers, and help build the engineering culture that carries us from 322 dealers to 1,000+.

This is a hands-on leadership role with a clear growth path. As we scale the team, you’ll grow into leading your own development pod.

You’ll report directly to the CTO.

We are an AI-first engineering team. That’s not a buzzword — it’s how we actually work.

AI agents are primary code authors in our workflow. Your job isn’t to type every line — it’s to architect the systems, define the specs, design the process flows, and ensure the components fit together.

You review, guide, and direct. You focus on outcomes, not keystrokes.

If micromanaging every line of code is how you work, this isn’t the right fit. If the idea of directing AI agents, designing systems at a higher level of abstraction, and focusing on architecture and outcomes instead of keystrokes excites you — keep reading.

Architecture & System Design (30%) — Own the technical architecture for our platform migration and new product development. Design APIs, data models, and service boundaries. Make decisions that stick.

Hands-On Development (30%) — Write and ship production code. Help choose and establish the modern stack we’re building on. You’re a player-coach, not a clipboard holder.

Code Review & Quality (20%) — Review PRs (both human and AI-generated), manage releases, and maintain engineering standards. Own production reliability alongside the team.

Mentorship & Team Growth (20%) — Mentor junior developers. Share knowledge. Help build the team and processes that let us scale. Grow into leading your own development pod.

You’ve been building software professionally for 7+ years and you’re still getting better — because you make yourself better, not because someone told you to.

The AI landscape, the tooling, the architecture patterns — they’re all changing fast. We need someone who’s already keeping up on their own and bringing what they learn into their work. Not reading about it someday. Applying it now.

• Strong backend experience — we’re evaluating Go, Rust, and Node.js/TypeScript for our next-generation platform. Deep expertise in at least one; curiosity about the others.
• Experience designing and building distributed systems or service-oriented architectures
• You’ve migrated legacy systems before — or at least understand why it’s hard and how to do it without breaking everything
• Comfortable with PostgreSQL, MariaDB/MySQL, Redis, Docker, and AWS
• You’ve done code reviews, managed deployments, and handled production incidents — not just written features
• Genuine enthusiasm for AI-assisted development — you’re already using AI coding tools and have opinions about them
• Self-directed and continuously learning — you stay current because you’re wired that way, not because it’s in your job description

• PHP/Laravel experience (helpful for the migration, not the future)
• Experience with AI/ML products, LLM integrations, or conversational interfaces
• Hands-on experience with AI coding tools (Claude Code, Cursor, Copilot, or similar)
• Prior team lead experience or mentorship in a small team
• Familiarity with automotive, SaaS, or CRM platforms

• A massive engineering org where you’re a cog
• Months of planning before anything ships
• A “we’ve always done it this way” culture
• Fear of AI replacing developers
• People who stopped learning three years ago

• A small team where your decisions have immediate, visible impact
• Direct access to the CTO and real influence over architectural direction
• An engineering culture that treats AI as a force multiplier, not a threat
• Real production systems serving hundreds of dealerships — not a science project
• Room to grow into engineering leadership as the team scales
• Competitive salary and benefits
• Hybrid work in Toronto

Send us:

1.    Your resume

2.    An architecture decision you made that you’d make differently today — What was the context? What would you change? What did you learn?

3.    How you stay current — The field is moving fast. What’s the most recent thing you learned that changed how you actually work — not just something you read about?

4.    Your experience with AI-assisted development — What tools have you used? What worked, what didn’t? How has it changed how you approach building software?

5.    Something you’ve built or contributed to — GitHub, deployed product, open source, side project — show us how you think through code and systems.

Short answers are fine. We want signal, not essays.
