Senior Software Engineer, Agentic AI Products Leo Berwick is an innovative mergers and acquisitions consulting firm. As a growth‑stage company, we move quickly, work collaboratively, and value people who take initiative and thrive in a fast‑paced environment. Our culture is grounded in high performance, continuous learning, and the shared ambition to build something exceptional, together.

We are building a suite of AI‑native tools that will change how Leo Berwick delivers advisory work and how our clients engage with us. We are hiring a Toronto‑based Senior Software Engineer to join our founding in‑house engineering team and build products from the ground up. You won't just be building wrappers around LLMs.

You'll architect the 'harness'—the orchestration middleware that manages agentic workflows, handles complex context packing, and integrates frontier models with enterprise data to automate high‑stakes M&A; workflows. You get the pace and ownership of an early‑stage product team, backed by the domain expertise, client relationships, and built‑in distribution of an established firm, with direct access to firm leadership. Our product is already proven with internal users, so you spend your time building and shipping, not searching for product‑market fit.

This is a hybrid role, with a minimum of two days per week in our Toronto office location. Want to build a new product from the ground up and own what ships Enjoy working directly with non‑technical subject matter experts and turning their knowledge into product Want your work in the hands of real users quickly,



with the potential to see internal tools evolve into client‑facing, commercial SaaS products Design and build agentic features and workflows, such as document and data extraction, multi‑step engagement workflows, and governance controls, from prototype to production, moving toward 'automated associates' that handle complex tasks like document triage, automated agentic pipelines, and project management. Design and implement robust data/domain models that support automated reporting and memo generation via Model Context Protocol (MCP) and other structured data exposure layers.

Write high‑quality, production‑grade code across the stack. Help define the architecture and technology stack for a new, modern platform, and build it from the ground up. Contribute to engineering standards, code reviews, testing, scalability, manageability, and security and governance practices for AI‑enabled systems.

Work alongside senior technology advisors and subject matter expert builders embedded full‑time in the product, iterating quickly on feedback from internal users. Work in small, focused pods with in‑house and external engineers, sharing knowledge so team capability compounds over time. Take part in technical evaluations,



including case‑study style discussions, and help hire other engineers as the team grows.

You are a senior engineer with 7–15 years of professional software engineering experience, a strong academic foundation in computer science, engineering, or mathematics, and a proven record of driving technical delivery in complex, high‑stakes environments. A track record of shipping. You've built enterprise SaaS or B2B products, and in the last 24 months you shipped an Agentic or LLM‑powered product you contributed to hands‑on.

Startup or founding‑team experience is an asset. You've built or worked within an AI "harness", the middleware that orchestrates agents (Fireworks AI or similar orchestration layers). Sound architectural judgment.

You can articulate the trade‑offs between domain‑driven design and monolithic architectures, and you know orchestration patterns such as enterprise service buses. You are robust in React, TypeScript, and Java, and comfortable picking up other languages, such as Python, as the work demands. This is a permanent full‑time role with a base salary range of $160,000 –$180,000 CAD.
