Senior Backend Developer — BoostSecurity (Montreal, QC)

BoostSecurity secures the software supply chain for engineering organizations. Our platform covers the whole path from developer to production: code, dependencies, CI/CD pipelines, containers and cloud. It connects to GitHub, GitLab, Azure DevOps and Bitbucket, finds the risks that matter, and puts the fix in front of the developer who can apply it. [One line on customers or funding stage that you're comfortable making public.]

We're a small, senior team, and we build software differently from how we did a few years ago. Each of our developers works with a team of AI coding agents. Agents draft the plans, write the code and tests, and run in parallel across many repositories. The developer owns the architecture, the judgment calls and the quality bar. If you've wondered what senior engineering looks like when writing the code is no longer the bottleneck, we'd like to show you.

Want to ship real features to customers in days, not quarters

Have started using AI agents as real collaborators, not just autocomplete, and want to push that further

Care more about getting the design right, about correctness and clean code, than about how many lines you wrote

Shape the architecture of an event-driven platform built on Python microservices, Kafka,



MariaDB and GraphQL, running on AWS and Kubernetes

Improve the tools that make the team fast: skills, agent workflows, CI and test infrastructure. Encoding what you know so agents get it right the next time is part of the job.

Hold a high testing bar (we target 100% coverage across unit, integration and module tests) and keep continuous deployment protected

Work with Product, Frontend and Security Research to decide what's worth building

7/4]+ years building high-quality, high-performance backends, ideally event-driven microservices

Strong Python. Go, Rust or TypeScript is a plus, since our scanners and dashboard use them.

Cloud-native experience on AWS, with infrastructure as code (Terraform) and Kubernetes

A record of diagnosing hard problems in distributed systems: performance bottlenecks, consumer lag, race conditions, database contention

Hands-on experience with AI-assisted development (Claude Code, Cursor, Copilot agents or similar), and opinions on where it helps and where it hurts

Experience with source-control platform APIs (GitHub, GitLab, Azure DevOps)

Helm, ArgoCD and continuous deployment experience

Experience building tools or workflows around LLMs
