About the role
- We are hiring a Senior Software Engineer to build and run the platform behind our certificate management, TLS and vulnerability monitoring, uptime, and security products.
- The platform is a TypeScript monorepo utilizing Fastify and Express services, Next.js and React frontends, MySQL and Redis, queues and workers on AWS, and deployed to Kubernetes through Terraform, Helm, and Azure DevOps pipelines.
- You will own features end to end, from schema and API through UI, pipeline, and production.
Responsibilities
- Design, build, and ship features across the full stack: Fastify or Express APIs, Next.js and React frontends, MySQL schemas and migrations, SQS-driven workers, and the infrastructure that runs them.
- Own services in production: observability with Sentry and Grafana, on-call participation, incident root-causing, and the follow-through fixes.
- Build and evolve security and monitoring products that scan, probe, and score real customer infrastructure at scale, with correctness and performance budgets that matter.
- Maintain and incrementally retire legacy .NET and Python components, moving behavior into the TypeScript platform with parity verified rather than assumed.
- Extend CI/CD and infrastructure: Azure DevOps pipelines, Docker images, Helm charts, and Terraform for EKS, RDS, SQS, and related AWS services.
- Integrate third-party and partner APIs (certificate authorities, scanners, identity providers) and keep those integrations resilient.
- Use AI-assisted development tools as part of daily work, and build AI-backed features where they genuinely improve the product.
- Review code, write tests, and raise the bar on standards that apply to human and AI-generated code alike.
- Mentor other engineers and write up decisions so others can act on them without you in the room.
Requirements
- 6+ years building and operating production web services and the frontends on top of them.
- Strong TypeScript and Node.js, including a modern API framework (Fastify preferred, Express acceptable) and a React framework (Next.js preferred).
- Production experience in more than one language or ecosystem, and at least one stack change you drove or adapted to in the last few years.
- Solid relational database skills on MySQL or Postgres: schema design, migrations, indexing, query performance, and transaction and locking behavior.
- Comfort owning what you ship: logging, metrics, alerting, and calm, evidence-led debugging in production.
- Security awareness as a habit: authentication and authorization flows, secrets handling, input validation, and dependency hygiene.
- Clear written communication.
Preferred qualifications
- Hands-on AWS (compute, queues, storage, secrets) and the ability to read and change Terraform.
- Containers and Kubernetes at a working level: writing a Dockerfile, reading a Helm chart, debugging a failing pod.
- CI/CD pipeline work in Azure DevOps or similar, plus Cloudflare or AWS WAF experience.
- Grafana, Sentry, or equivalent observability tooling beyond basic dashboards.
- Experience with PKI, TLS, or certificate lifecycle management, or with monitoring and scanning products (uptime, vulnerability, DNS or email security).
- OAuth 2.0 and OpenID Connect implementation experience, especially multi-tenant identity providers.
- C# and .NET, enough to read, maintain, and migrate legacy services without making them your home.
- Python for data pipelines, scanners, or tooling.
Benefits
- Competitive compensation and comprehensive health, dental, and vision coverage
- Retirement savings programs with company matching (401(k) or RRSP)
- Generous paid time off, including holidays, and vacation
