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.
  • 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 system engineering to evaluate optical concepts of operations and assess end‑to‑end feasibility.
  • Develop robust modeling tools and frameworks to support…
