Original job description

About the roleParabellyx Cybersecurity is hiring a mid-to-senior Full Stack Developer, weighted toward the backend, to build and run the data and scanning engine behind Luma. You will own the pipeline that turns raw scan results into the insights clients see, plus the APIs and databases underneath.Luma is our client-facing security platform. Luma Perimeter scans external attack surface and reports security scores and alerts daily across dozens of client organizations; Luma Cloud extends that into cloud posture. You will work directly with engineering leads and the security practice, and your work ships to real clients.

Parabellyx specializes in offensive security and continuous testing for leading Canadian and U.S. organizations, with offices in Richmond Hill, ON and Denver, CO.

What you will do

Build and maintain the scanner and insights pipeline: ingest scan output, normalize it, score it, and store it for reporting

Design and ship REST APIs that serve the Luma client portal, internal tools, and integrations

Own database design and performance: schema changes, migrations, query tuning, and data retention

Build ETL and background jobs that run reliably on a daily cadence, with monitoring and alerting for failed or missed runs

Contribute to the client portal and internal dashboards on the frontend when a feature needs it (about one fifth to one third of your time)

Write tests, review code, and document systems so the team can run them

Partner with the security team so findings become clear, accurate alerts and scores clients can act on

Help evolve CI/CD and day-to-day operability of the platform

What we are looking for

4+ years professional software development, with a clear backend emphasis and enough frontend ability to deliver a feature end to end. Mid and senior candidates welcome; we level the offer to experience

Strong experience building and operating APIs and services in Python (FastAPI / similar); comfort working in a modern TypeScript codebase

Solid relational database skills on PostgreSQL: schema design, indexing, migrations, diagnosing slow queries

Experience with data pipelines or scheduled processing, including large, messy, or inconsistent inputs

Working knowledge of React and TypeScript (Angular a plus) and ability to ship UI without hand-holding

Comfort with Git, code review, CI/CD, Docker/containers

Clear written communication - we are distributed; decisions and handoffs happen in writing

Eligible to work in Canada without sponsorship; able to pass a CPIC background check and provide references when requested

Nice to have

Cybersecurity exposure (preferred): vulnerability scanning, attack surface management, secure coding, or work in a security product / SOC - candidates who know what a finding means build better alerts

Experience with workflow / orchestration engines, especially Prefect (or similar: Airflow, Dagster, Temporal)

Cloud experience, especially Azure (AWS also useful), plus IaC and managed container services

Familiarity with open-source cloud security or ASM tooling

Object storage, queues, and observability tooling

Azure AD/B2C, GitHub Actions, Pandas, OpenAI / AI-assisted features

.NET or Microsoft Graph exposure

Compensation and how we work

CAD $110,000–$150,000, dependent on seniority.

Small product team, real ownership, hybrid from Richmond Hill with flexible remote options across Canada.

How to apply

Apply on LinkedIn (answer the screening questions), or send your résumé and a short note on a backend system you built and are proud of.

Parabellyx is an equal opportunity employer.
