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.

Key Responsibilities:

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

Maintain awareness of emerging optical technologies and assess their applicability to Kepler’s mission roadmap

Standards, Protocols & Interoperability

Serve as the internal authority on SDA, ESTOL, and other optical communication standards, ensuring Kepler’s systems align with evolving requirements

Translate standards into system behaviors, interface requirements, and operational concepts

Engage with standards bodies, government organizations, and industry partners to support interoperability and cross-system compatibility

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

Partner with mission design and systems engineering to evaluate optical concepts of operations and assess end-to-end feasibility

Develop robust modeling tools and frameworks to support ongoing constellation-level analysis

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

External Engagement & Thought Leadership

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

Communicate complex optical concepts clearly to internal and external stakeholders

Required Skills & Qualifications:

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

Demonstrated ability to assess vendor capabilities and understand system-level integration considerations

Familiarity with SDA, ESTOL, and other relevant standards frameworks

Proficiency with modeling/simulation tools (e.g., MATLAB, Python, STK, Zemax/OpticStudio)

Excellent communication and cross-functional leadership skills

Preferred Qualifications:

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

Participation in interoperability or standards development working groups

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 collaborative environment

Use of AI in Recruitment

At Kepler Communications, all hiring decisions are made by people. Human recruiters are involved in every step of our recruitment process. We use AI-based tools (such as Lever AI and HireEZ) to assist with the initial review of applications by ranking candidates based on job-relevant criteria. These tools support - but do not replace - human judgment.
