About Quadrical AI

Quadrical AI is a B2B SaaS company helping renewable energy asset owners and managers — across solar, storage, and wind — increase plant generation and manage complex portfolios with precision. Headquartered near Toronto, Canada, we operate globally and are building fast. We have early customers, a validated platform, and a clear direction. What we are building now is the commercial layer that takes this company to scale.

The Role

We're looking for an experienced Senior Backend Developer to help architect & scale the core backend systems that power our platform. This role is designed for experienced engineers who prefer strong ownership, independent execution, & working on backend systems at scale. 

You will work closely with frontend engineers, product teams, and leadership to build applications used by renewable energy operators globally. The expectation is ownership: of code quality, user experience, performance, and continuous improvement. This is a role for someone who wants to grow quickly in a fast-moving environment while working on meaningful real-world problems at the intersection of Climate, AI, and SaaS.

Key Responsibilities 

Design & implement efficient & scalable backend applications using Python.

Collaborate with front-end developers to integrate user-facing elements with server-side logic.

Develop & maintain REST APIs.

Build & maintain databases [like PostgreSQL, MySQL] & data models.

Write unit tests & ensure code coverage.

Troubleshoot & debug issues reported by customers or internal teams.

Continuously learn & adopt new technologies & tools to improve our development processes & software quality.

What We Are Looking For

Minimum 4 years of hands-on experience in backend development.

Strong understanding of Python programming language & related libraries/framework [for example - Pandas, Fast, Flask, matplotlib]

Strong understanding of databases, data modelling & SQL [for example, PostgreSQL, MySQL]

Experience with Git & modern version control workflows.

Strong fundamentals in data structures, algorithms, & object-oriented design.

Solid experience designing & consuming REST APIs

We'd love if you also have these skills

Exposure to AI/ML pipelines /applications.

Familiarity with cloud computing services [e.g. AWS, Azure]

Experience with containerization technologies [e.g. Docker, Kubernetes]

Experience with agile software development methodologies [e.g. Scrum, Kanban]

Experience with Energy and/or Electrical products. 

Why Join Us

The global renewable energy market is valued at over USD 900 billion and is compounding. Quadrical sits at the intersection of this growth and the software intelligence layer the industry urgently needs.

We run a flat, high-accountability team that spans cultures and time zones. Joining at this stage means real visibility, real learning, and the opportunity to shape how we show up commercially as a company. For the right person, this role is a launchpad — not a landing spot.

Competitive salary and a work environment where initiative is recognised and rewarded. Also, if you'd like to work remotely after 6 months, we are open to the discussion.
