At Kepler Communications, we’re not just imagining the future of on‑demand space connectivity – we’re leading it! Our mission is to provide real‑time Internet access for space‑based assets, enabling a new era of data‑driven exploration and innovation. With 33 satellites launched to date, Kepler operates the first commercial optical data relay constellation, enabling real‑time, continuous space communications while supporting advanced on‑orbit compute and hosted payload capabilities.

Industry‑leading technology is only part of the story. Competitive compensation with a robust equity plan to share in our success. ~ Comprehensive coverage for health, dental, and vision insurance – including dependents. ~ Unlimited vacation, supportive parental leave policy, and company‑wide holiday shutdown. ~ Semi‑annual company‑wide parties and frequent in‑office team events. ~ Relocation packages available for approved roles. ~$Fully stocked Toronto office kitchen with snacks, drinks, games and top‑notch kitchen appliances. ~ Position: Optical Architect We are seeking an experienced Optical Architect to lead the architecture, evaluation, and mission‑level integration of laser‑based optical communication systems for Kepler’s space networking products. This role focuses on defining how optical technologies fit into our broader system architecture, ensuring technical compatibility, operational performance, and adherence to industry standards.

The ideal candidate combines deep expertise in free‑space optical communications with the ability to translate complex technology capabilities into system‑level designs and mission strategies. You will collaborate closely with internal teams and external partners to ensure that selected optical solutions meet our performance, interoperability, and mission needs.

Optical System

Architecture & Technology Assessment Define end‑to‑end architecture for optical communication capabilities across Kepler’s products and constellation.



Evaluate optical communication technologies, terminals, and subsystems provided by external partners and suppliers. Develop system‑level requirements and integration strategies, ensuring compatibility with spacecraft, ground systems, and network architecture.

Perform optical performance modeling (link budgets, pointing requirements), technology trade studies, and risk assessments. Participate and support in‑orbit optical commissioning, anomaly investigation and continuous operational support. Serve as the internal authority on SDA, ESTOL, and other optical communication standards, ensuring Kepler’s systems align with evolving requirements.

Provide technical guidance on protocol implementation and architectural impacts.

Mission Analysis, Link Strategy & Availability Modeling Lead detailed mission‑level optical performance and availability analysis, including visibility modeling, atmospheric effects, and time‑dependent link dynamics. Define optical link strategies, diversity concepts, and operational modes to optimize reliability and network performance. Cross‑Functional Technical Integration Guide internal teams on how optical communication capabilities integrate with spacecraft platforms, avionics, software, and ground infrastructure.

Collaborate with product and systems engineering teams to translate operational needs into architectural decisions and interface requirements. Represent technical considerations in supplier discussions, partner evaluations, and customer engagements. Participate in technical reviews and contribute to system‑level design decisions across the organization.





Act as a technical representative for Kepler in discussions with suppliers, partners, standards organizations, and customers. Contribute analysis, architectural insights, and technical leadership to support business development and partnerships. Advanced degree in Optical Engineering, Physics, Electrical Engineering, Aerospace Engineering, or related field. ~7+ years of experience in free‑space optical communications, including system modeling and architecture. ~ Strong knowledge of optical communication technologies, ATP concepts, and link analysis. ~ Proficiency with modeling/simulation tools (MATLAB, Python, STK, Zemax/OpticStudio). ~ Excellent communication and cross‑functional leadership skills.

Experience working with suppliers or partners providing optical communication terminals or subsystems.

Background in constellation networking, spacecraft architecture, or mission operations. Understanding of optical terminal integration constraints (thermal, mechanical, optical, pointing, and interface‑level considerations). Ability to drive technical strategy within a fast‑paced, externally team-oriented environment.

Salary Range: $160,595 – 210,595 CAD. Actual total compensation will be determined at the Company’s discretion and is based on a variety of job‑related factors, which may include, but are not limited to, relevant knowledge, skills, experience, performance, and education and/or training.
