Sectigo is hiring a Principal Systems Engineer

We are building next‑generation trust infrastructure and high‑performance systems that power certificate lifecycle and emerging industry trust models. This Principal Software Engineer position is a senior, hands-on distributed systems role focused on trust infrastructure while building production-grade backend services at scale. You will work on systems that require high correctness, reliability, and operational discipline. This role extends beyond internal development. You will collaborate across the broader ecosystem and upstream open-source projects, helping shape how modern trust infrastructure is implemented and operated in production—not just consuming it. As our trust platform evolves alongside industry direction, this role will naturally expand across adjacent trust and security infrastructure concerns. Who You Are • Builder of foundational systems with strong ownership mindset. • Comfortable operating at scale and making high-impact architectural decisions. • Pragmatic, disciplined, and focused on production outcomes. • Able to collaborate across teams and influence beyond organizational boundaries. This is a full-time position, working in a hybrid model, and reporting to our Ottawa office at least 3-4 days a week. The target compensation package for this role is between CAD 130,000 and CAD 170,000, subject to internal equity and years of experience.  We may make further adjustments through an approval process if the targeted compensation range needs to be modified based on business needs and market trends. Here are the core functions, responsibilities, and expectations for this role:  • Design and build high-performance distributed services in Golang. • Scale systems for certificate issuance, validation, and lifecycle operations. • Define and deliver production-grade reliability (availability, resilience, observability). • Drive early architecture decisions impacting scalability, failure behavior, and cost. • Translate evolving standards into real-world, production-ready systems. • Collaborate with ecosystem partners and contribute upstream to open-source projects. • Ensure systems are deployable, operable, and portable beyond single environments. • Additional tasks associated with this position may be assigned in response to company initiatives and business needs.
