Job Description

Full Stack Engineer

Hybrid remote (once a month in the Toronto office)

Sage Recruiting is partnering with a fast-growing SaaS startup that’s bringing modern engineering to one of the most outdated industries around. Their work directly affects the reliability of the electrical grid and the way major utilities operate. If you’ve ever looked at repeated outages and thought technology should be doing more, this will speak to you.

They’re building agentic AI for utilities, automating the internal processes that slow the industry down. They focus on high-value workflows like asset management, regulatory work and customer operations. Think Palantir, but built specifically for utilities.

Their platform ingests massive amounts of utility data, runs it through a custom retrieval engine and turns it into insights people can actually use. They already have customers in production with more launching in January. You’d be joining a small, thoughtful team with a good sense of humour and a lot of passion for building meaningful products. You’ll work directly with the founder in a low-ego, high-trust environment.

They’re hiring multiple engineers, all full-stack with a backend focus , to work on the core product. You could also mix in some work with ETL or on their RAG engine using Python if that’s of interest. There’s room to carve out the lane that fits you best.

What you’ll do

You’ll work on everything from early concepts to production-ready features. That includes shaping domain models, building out the backend, and creating the first versions of new product areas. You’ll test ideas with utility partners and refine them into tools the industry will actually use. The work can be ambiguous, partly because customers don’t always know what they need until they see it, but that’s what makes it interesting. If you enjoy presenting your work to customers, you can jump in. If you’d prefer to stay focused on building, that’s completely fine too.

Tech you’ll touch

• TypeScript (node.js / express) for backend services
• React with Material UI
• PostgreSQL
• GCP
• Microservices with some event-driven pieces
• RESTful APIs
• (optional) Python for ingestion and the RAG engine

Who you are

You’re either Senior or Staff level and have experience taking features from concept to completion. You understand database design and system architecture. You’re comfortable in TypeScript or Python, ideally both. You learn quickly, especially when the domain is new or confusing, you can work independently, and you’re able to figure out difficult problems independently. You like getting into the guts of a problem instead of waiting for a perfect spec. You are comfortable with ambiguity, change, fast-paced working and autonomy.

Mostly, you’re someone the team enjoys working with. A sense of humour is appreciated. Kindness and curiosity go a long way.
