This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Principal Software Engineer, Docker Hardened Images based in Canada. This is a high-impact principal-level individual contributor role shaping the future of secure container delivery at scale. You will define the architecture and long-term strategy behind a catalogue of security-hardened container images and Helm charts used in enterprise and regulated environments. The role sits at the intersection of container security, supply chain integrity, and platform engineering, influencing how software is packaged, verified, and distributed across a global developer ecosystem. You will operate across multiple teams and organizational boundaries, driving alignment on complex technical tradeoffs that span upstream open-source ecosystems and enterprise customer needs. This is a deeply strategic role where your impact comes through technical vision, architectural leadership, and standards-setting rather than direct management. You will help define how secure-by-default software delivery evolves in a world increasingly shaped by AI-driven and autonomous workflows. \n

Accountabilities: Define and drive multi-quarter technical roadmaps for container hardening, balancing security posture, upstream velocity, compliance requirements, and scalability. Identify systemic patterns across customers, operations, and upstream signals, translating them into platform-wide architectural improvements. Establish and evolve engineering standards for image creation, Helm chart adaptation, supply chain security (SBOM, SLSA, Sigstore), and release governance. Drive alignment across engineering, product, security, and executive stakeholders on complex technical strategy and sequencing. Represent the organization in critical customer engagements and open-source communities on topics related to secure container delivery. Shape platform tooling, CI/CD systems, and integration test strategies to ensure scalability, reliability, and high-quality releases. Mentor senior and staff engineers, raising the overall technical bar through design leadership, reviews, and architectural guidance. Participate in on-call rotations and contribute to resolving high-severity incidents while driving long-term reliability improvements. Requirements: 10+ years of backend or platform engineering experience building production-grade distributed systems at scale. Strong expertise in Kubernetes and the broader cloud-native ecosystem, with the ability to reason about tradeoffs across tools and infrastructure components. Deep understanding of container supply chain security concepts including SBOMs, signing, provenance, attestation, and SLSA frameworks. Proven ability to define multi-quarter technical roadmaps and align diverse stakeholders around architectural direction. Experience influencing engineering direction across multiple teams or organizations without formal authority. Strong programming fundamentals, with practical experience in Go and modern CI/CD and testing systems. Experience engaging with open-source communities and shaping upstream decisions in security-relevant domains. Ability to communicate complex technical strategy clearly across technical and executive audiences in distributed environments. Preferred: Experience with regulated environments such as FedRAMP, PCI, or FIPS compliance. Prior experience as a package maintainer or contributor in Linux distributions or similar ecosystems. Hands-on experience implementing supply chain security tooling at organizational scale. Experience in enterprise customer-facing technical leadership roles. Prior Principal or Distinguished IC experience in platform, security, or developer tooling domains. Benefits: Competitive compensation including base salary, bonus opportunities, and equity participation Remote-first flexibility with a globally distributed engineering culture Comprehensive healthcare coverage (medical, dental, vision) depending on location Retirement and savings plans with employer contributions (varies by country) Paid parental leave (up to 16 weeks after eligibility period) Generous PTO policy encouraging rest and personal time Annual technology stipend and home office setup support Training and learning budget for conferences, courses, and professional development Quarterly wellness-focused “Whaleness Days” and end-of-year break Equity grants allowing employees to share in company growth Community perks including swag, team events, and remote engagement programs
