Principal Software Development Engineer - Applied AI, who enjoys tackling hard problems and wants to create meaningful impact for small businesses across Canada. You’ll set the technical strategy for AI Products at Wagepoint, authoring thearchitecture decision records that define platform boundaries, persistence standards, and quality gates for every team building AI features, and setting the guardrails that let Engineering teams experiment with agentic AI. You will report directly to our
VP, Engineering.Your decisions are the ones other engineers’ proposals must cite and align to. Other teams’ roadmaps depend on getting your calls right. You’ll keep Wagepoint’s AI platform choices current against a fast-moving landscape, articulate tradeoffs in terms leadership can act on, and multiply the org through mentorship, pairing with and unblocking the engineers building on your standards.Like every Principal Engineer at Wagepoint, you also carry broad architectural leadership beyond AI, including well-architected, highly performant distributed systems, and AI-augmented development practices across the SDLC.Like every engineer at Wagepoint, you do not write software by hand. You’re a major contributor to the software factory, the agentic pipeline of specs, agent implementation, agent review, and human approval that produces our software. You’ll own specific agents within it and work with your teammates to constantly improve the factory itself.Wagepoint’s goal is Level 4 on our agentic development ladder (engineers approve the spec, agents implement and review, engineers approve the PR), advancing toward Level 5 over time, without ever compromising quality in our highly regulated payroll and tax reporting environment. You are responsible for making that transition possible.85% of your focus is customer-facing AI products and the platform beneath them. The rest goes to building Wagepoint’s internal use of AI and our software factory.This role is measured by scope of influence, not just personal output.What You'll Be Expected To Own:Author the decision records that define how AI gets built org-wide, and resolve cross-team ambiguity with written, cited decisions.Define and maintain the boundary between AI services and the product stack, and own the shared service kit.Make quantified platform calls (evals, observability, persistence) against named vendors with cost models.Define how every AI team gates quality: eval standards in CI/CD, drift monitoring, release criteria.Set resource-isolation and agentic-workflow guardrails, and own the responsible AI and audit posture org-wide.Keep platform choices current against the landscape, and publish dated verification notes and revisit triggers.Lead design of large-scale, distributed, customer-facing systems where AI intersects the product stack, and apply DDD to define domain boundaries.Be a go-to technical resource across teams, unblock high-impact initiatives, and shape engineering-wide standards through RFCs and reviews.Set the org-wide path from today’s baseline to Level 4 of the agentic development ladder and beyond toward Level 5, while holding the quality and compliance bar required in payroll and tax reporting.What You Bring To The Table:10+ years of professional software engineering experience with progressively increasing impact, including multiple years designing and operating production LLM/agentic systems at Staff-level scope or above.Proven technical leadership designing distributed systems and microservices for complex domains, with working knowledge of DDD and Clean Architecture principles applied to build highly performant, well-architected systems (prior DDD project experience not required).Full-stack breadth, spanning modern front-end frameworks and a Python back-end, sufficient to lead architecture across the entire product stack, not just AI services. .NET/C# experience is a plus, not a requirement.Track record of authoring architecture standards adopted beyond your own team, producing decision records that other senior engineers review, cite, and build on.Demonstrated quantified build-vs-buy decisions against named vendors (e.G., eval/observability platforms, vector stores), with cost models and explicitly rejected alternatives.Deep fluency in the current AI platform landscape: stateful agent orchestration, MCP and inter-agent (A2A) interoperability, eval-gated CI/CD, and vector-enabled persistence (PostgreSQL/pgvector, DiskANN-class indexing, managed offerings).A considered point of view on where Wagepoint’s model strategy should be in two years, including whether and where to adopt fine-tuned small language models versus frontier APIs, grounded in cost, latency, and control tradeoffs.Experience defining platform boundaries between AI stacks and an existing product stack (e.G., Python AI services alongside .NET), including shared service-kit libraries other teams consume.Security and governance leadership: resource isolation, agentic workflow guardrails, responsible AI in a regulated, money-movement domain.Executive communication, articulating platform tradeoffs in terms leadership can act on, covering cost, risk, and optionality, not just engineering detail.A high degree of agency, building net-new systems and optimizing API performance where no established pattern exists, forging the path rather than waiting for one, with demonstrated ability to bring other engineers along that path.Demonstrated multiplier effect through mentorship: pairing with, unblocking, and growing senior engineers.A passionate and key contributor to Wagepoint’s software factory, directing and reviewing agentic development while maintaining and improving our high quality and compliance bar.What we bring to the table:Impact:
