About Castelion

Castelion is bringing a new approach to defense development and production: one that focuses on short, iterative design cycles, rapid testing in development, and modern commercial manufacturing strategies for production at scale. We’re designing, building, and testing next generation long range strike weapons systems to give America and its Allies a definitive edge and deter future conflicts.

Senior Radar Systems FPGA Engineer

As a Senior Radar Systems FPGA Engineer you will be at the forefront of defining, implementing, and testing the code that drives our radar seekers. Embedded processors with both FPGA fabric and CPU cores form the backbone of many radar systems. You will be writing and testing FPGA and C/C++ code for both command/control and data processing. Your role involves close collaboration with fellow Castelion engineers across missile-level and seeker-level software and hardware domains. We seek intelligent, collaborative, and driven engineers who are passionate about problem-solving and eager to contribute to an extraordinary mission. If you thrive in challenging environments and are excited by the prospect of making a tangible impact, we want to hear from you.

Responsibilities

System Synthesis: From seeker requirements, derive and define the compute and code requirements. Lead the part selection trade study for major computer components. Develop innovative ways to solve problems with low-cost hardware that readily scales.

Algorithm Implementation: Efficiently implement radar signal processing algorithms. Work with the team to balance sensor performance, compute resources, timeline, cost, thermal, power consumption, volume, etc. Your role includes algorithmimplementation process, from initial design, prototyping, and testing to final integration and deployment for mission-critical applications.

Command/Control Implementation: Develop and approach and subsequent code to properly control the radar across all modes. This includes gathering/reporting telemetry, in-test diagnostics, and approaches for recording high speed data during test.

Collaboration: Partner with multidisciplinary engineering teams to brainstorm, design, and develop next-generation hypersonic missile capabilities, including advanced guidance algorithms and integrated seeker image processing.

Project Leadership: Lead major projects that propel Castelion’s mission forward, ensuring alignment with overall objectives and occasionally traveling to launch and customer sites for testing and operations.

Basic Qualifications

Educational Background: Master’s degree in computer science, computer engineering, electrical engineering, math, or a related STEM field.

Technical Proficiency: 10+ years of professional radar engineering experience. Seeker experience is preferred.

Preferred Skills and Experience

System Experience: Practical experience with radar calibration, test and deployment. Prefer experience in missile domain.

Technical Skills: Highly skilled FPGA coder, familiar with development tools of major FPGAs, familiar with radar signal processing and calibration techniques.

Problem-Solving: Innovative problem-solving approach using first-principles thinking, including developing prototypes to validate key design concepts and quantify technical constraints.

All employees are granted long-term stock incentives as part of their employment as Castelion. All employees receive access to comprehensive medial, vision, and dental insurance, and the company offers three weeks of paid time off per year.

Leadership Qualities

Bias to Action and Creative Problem Solving. Desire and experience questioning assumptions in ways that lead to break through ideas that are ultimately implemented. Successfully bring in applicable processes/concepts/materials from other industries to achieve efficiency gains. Ability to personally resolve minor issues in development without requiring significant support.

High Commitment, High Initiative. A successful candidate will have a genuine passion for Castelion’s mission and consistently look for ways to contribute to the company’s technical goals and prevent hardware blockers. Ability to work in a fast paced, autonomously driven, and demanding atmosphere. Strong sense of accountability and integrity.

Clear Communicator. Proactively communicates blockers. Trusted in previous roles to be voice of company with regulators, suppliers, gate keepers and customers. Capable of tactfully managing relationships with stakeholders to achieve company-desired outcomes without compromising relationships. Emails, IMs and verbal interactions are logical, drive clarity, and detailed enough to eliminate ambiguity.
