As Principal Engineer - Satellite Systems, you will serve as a senior technical authority across Kepler’s satellite and space mission activities. Reporting to the Senior Director of Satellite Systems, you will act as a chief engineer by influence, providing independent technical oversight, guidance, and validation across multiple projects rather than being embedded within a single program.

This role is intentionally designed as a cross-project, non-line-management position. You will operate as an internal technical customer and reviewer, ensuring engineering teams are making sound architectural choices, executing against best practices, and remaining aligned with Kepler’s technical strategy and mission objectives.

You will bring deep satellite system expertise and end-to-end mission experience, enabling you to challenge assumptions, identify risks early, and help teams stay on the right technical path as the company grows.

Key Responsiblities:

Please note: Though this role is remote, it will require monthly on-site work at Kepler's Toronto HQ

Senior Technical Authority:

Act as an independent technical authority across satellite missions and development efforts

Review and validate system architectures, requirements baselines, and major technical decisions

Ensure consistency and technical rigor across projects

Identify systemic technical risks and recurring challenges across ongoing work

Technical Review & Assurance:

Serve as a reviewer for major lifecycle milestones such as SRR, PDR, CDR, TRR, and FRR

Critically assess design outputs, trade studies, and verification approaches produced by engineering teams

Provide clear, actionable technical feedback to ensure teams remain on a sound and executable path

Support anomaly investigations and technical issue resolution when senior judgment is required

Strategy to Execution Support:

Translate Kepler’s satellite systems strategy into clear technical expectations and engineering guardrails

Support early-phase mission definition, concept development, and proposal activities

Help teams convert high-level mission goals into executable and technically robust system designs

Advise leadership on technical readiness, maturity, and risk across ongoing and proposed efforts

Mentorship & Technical Guidance:

Mentor systems engineers, architects, and technical leads through guidance, review, and coaching

Act as a trusted escalation point for complex system-level technical questions

Promote disciplined systems engineering practices and strong technical judgment across teams

Influence technical culture through expertise and example rather than formal authority

Cross-Functional & External Engagement:

Support technical discussions with customers, partners, and agencies as a senior subject matter expert

Contribute to institutional programs by ensuring compliance, rigor, and mission assurance expectations

Communicate complex technical assessments clearly to leadership and non-technical stakeholders

Balance institutional engineering discipline with startup agility and pragmatism

Required Skills & Qualifications:

Bachelor’s or Master’s degree in Aerospace Engineering, Systems Engineering, Electrical Engineering, or a related field

15+ years of experience in satellite systems engineering and space mission development

Demonstrated end-to-end space mission experience (concept through launch and operations)

Deep understanding of satellite system architecture, integration, requirements, and verification

Proven ability to operate as a senior technical authority across multiple concurrent efforts

Experience working in both institutional program environments and fast-moving commercial or startup contexts

Strong technical judgment and ability to influence without direct authority

Bonus Points:

Independent Technical Judgment: Comfortable reviewing, challenging, and validating complex designs

Systems Thinking: Strong ability to assess whole-mission impacts and cross-discipline trade-offs

Influence-Based Leadership: Builds trust and alignment through expertise rather than hierarchy

Execution-Focused: Keeps teams oriented toward practical, achievable outcomes

Clear Communicator: Able to translate complex technical issues into clear guidance and decisions
