AI Team Mission

Sagard is becoming an AI-first organisation. AI is expected to automate low-value work and materially improve how investment decisions are made.

Position Overview

We’re hiring a Senior Full Stack Engineer to our AI team at Sagard to design, build, and evolve the internal products and platform capabilities that underpin decision‑making and operations.

This is a senior individual contributor role for someone who is:

• Comfortable owning problems end‑to‑end, from a vague business question to a robust production solution
• Strong on infrastructure / platform and backend, but also comfortable working on the front end where needed
• Excited to create reusable building blocks so the rest of the team can move faster

Compensation range: CAD$130,000 to CAD$150,000

Responsibilities:

Platform, Architecture & Application Development

• Design and build full‑stack internal applications used by investment, finance, and operations teams (APIs, services, and front‑end experiences)
• Work across the stack: front‑end, backend, data layer, and cloud infrastructure
• Define patterns and abstractions that make it easy to ship new features quickly and safely (component libraries, service templates, shared modules)
• Design and build AI-enabled applications, including LLM-based agentic workflows and evaluations

Reliability, Quality & Operations

• Own the operational health of the applications and services you build: monitoring, alerting, performance, and incident response
• Implement and enforce testing, code quality, and deployment best practices (unit/integration tests, CI/CD, feature flags)
• Continuously improve performance, cost efficiency, and reliability of the platform and apps
• Own the production reliability of AI-enabled applications, including monitoring model quality, cost, latency, and failure modes.

Collaboration & Leadership

• Work directly with business partners and product owners to deeply understand their workflows and pain points, then translate them into pragmatic technical solutions
• Own the review of technical design documents and code reviews, setting a high bar for engineering quality, architectural soundness, and long-term maintainability
• Provide technical guidance and mentorship to forward deployed engineers
• Drive projects from problem framing through design, implementation, and rollout with minimal oversight

Qualifications:

We care more about how you think and build than any specific tool. You might describe yourself as a full stack engineer, platform engineer, or backend engineer with strong infra chops.

Must‑have experience

• Significant experience (typically 6+ years) in full stack / backend / platform engineering roles
• Proven ability to take an ambiguous problem, break it down, and independently deliver a production solution
• Strong foundation in backend engineering: designing and building APIs, services, and integrations
• Experience with at least one modern front‑end framework (e.g., React, Vue, Angular) and comfort working on user‑facing flows
• Solid understanding of cloud infrastructure (AWS, Azure, or GCP) and platform concerns: deployments, observability, configuration, permissions
• Solid software engineering practices: version control, code review, testing, CI/CD, and documentation
• Experience shipping AI features to production, or strong interest and ability to ramp fast
• Hands-on experience using AI-assisted coding tools to design, implement, test, and review production systems, with a clear understanding of their limitations and failure modes
• Ability to collaborate and communicate directly with non‑technical stakeholders, translate business needs into technical designs, and explain trade‑offs clearly

Nice to have

• Experience in financial services, asset management, private equity, credit, or fintech, especially building tools for investment, risk, or finance teams
• Experience designing internal platforms or reusable tooling for other engineers / analysts (platform or “enablement” teams)
• Experience with modern data platforms or analytics tooling (e.g., data warehouses, orchestration, metrics layers)
• Background in security, permissions, and access control for internal tools
