Agentic-AI Software Engineer Toronto, ON

We're looking for top-tier engineers - the best of the best - who use modern AI development tools (Claude Code, Codex etc) and multi-agent workflows to build and manage large custom applications at scale. This is a hands‑on role for someone with 1‑3 years of experience who wants to operate at the frontier of AI‑assisted development, ship production software, and learn fast alongside an exceptional team.

You’ll join the FPdev.ai team within FP Partners (fppartners.ca), which builds custom solutions for our portfolio companies – from internal applications and data infrastructure to refactoring large SaaS platforms to modern architecture. You’ll work alongside our Private Equity and Private Debt teams to ship real‑world software that drives meaningful business results.

Responsibilities

• Build and manage large custom applications at scale – internal platforms, data pipelines, and operational tooling – across our portfolio companies.
• Use AI coding assistants and multi‑agent workflows to ship faster – we value problem‑solving ability and velocity over memorizing syntax.
• Refactor and modernise large SaaS applications – migrating legacy codebases to clean, scalable, modern architecture.
• Move quickly from concept to prototype to production – launch, measure, and iterate.
• Collaborate with business users to understand requirements, showcase solutions, and ensure adoption.
• Measure and communicate impact using a clear framework: establish baselines, implement changes, and document results.

Qualifications

• Education : Bachelor's degree or higher in Computer Science, Applied Math, Engineering, Statistics, Physics, or related quantitative discipline (Master's preferred).
• Experience & Track Record : 1‑3 years shipping production software, paired with a standout record of excellence – first‑class standing, Dean’s Honours, top‑of‑class, or comparable signals of being among the best at what you do.
• Communication Excellence (critical) : Ability to produce clear written documentation (requirement specs, one‑pagers, technical guides); strong verbal skills – comfortable presenting demos, scoping projects, and bridging technical and business perspectives.
• Analytical Mindset : Ability to decompose complex, ambiguous challenges into actionable steps.
• Strong Programming Fundamentals & AI‑Native Approach : Fluent with AI coding assistants and multi‑agent workflows to build, manage, and ship applications at scale.
• Drive & Learning Agility : Action‑oriented, intensely curious, and energized by experimentation and fast, data‑driven iteration. Cultural fit and drive matter as much as raw skill.
• Experience refactoring or modernising legacy codebases and large SaaS applications.
• Production experience with AI development tools and agentic workflows (Claude, Codex, Cursor, multi‑agent orchestration).
• Background in a high‑performance environment – a top startup, technology company, consulting firm, or finance.

Why This Role Stands Out

• Modern development approach : Build and manage large applications at scale using cutting‑edge AI agents and multi‑agent workflows.
• Direct impact : Your work directly influences operational efficiency and bottom‑line results.
• Diverse challenges : Work across varied industries, codebases, and problems – constant learning and variety.
• Learn fast : Work shoulder‑to‑shoulder with an exceptional team of operators and technical leaders who have built and scaled real software.

What "Strong Communication" Looks Like Here

• Requirements gathering : Lead focused discovery sessions and document success criteria clearly.
• Presentations : Demonstrate value through storytelling – show the before state, your solution, and the measured improvement with live examples.
• User enablement : Develop release notes, setup guides, and onboarding materials that non‑technical teams find intuitive.
• Stakeholder management : Present options and timelines in plain language, facilitating informed decision‑making.

We’re looking for the best of the best. If you’re a top‑tier builder who communicates clearly, learns relentlessly, and ships at scale with AI – and you’ll thrive in a high‑drive, high‑trust team – we want to hear from you.
