We are seeking an RF Engineer with 2–4 years of experience to help design, develop and integrate the RF hardware and systems at the core of our radar technology. You will work closely with the Chief Engineer and the broader team to turn system level requirements into practical hardware solutions. This role spans the full RF engineering lifecycle from circuit level design and simulation to system level analysis, hardware characterization and integration. At Mithril, you won’t be limited to a single component or narrowly defined subsystem. You’ll have the opportunity to take ownership of challenging technical problems, contribute to decisions that shape the overall system and grow your expertise alongside an ambitious engineering team. We are looking for an engineer who combines strong technical fundamentals with practical problem-solving skills, intellectual curiosity and a willingness to take on challenges beyond a narrowly defined scope.
Description
What You’ll Do
• Design RF Hardware: Analyze, design, simulate and characterize RF circuits and
subsystems for advanced radar applications.
• Develop RF Architectures: Support the design and integration of transmit and
receive chains, including amplifiers, filters, switches and mixers.
• Analyze System Performance: Perform RF link budget analysis including noise
figure, gain, dynamic range assessments and non-linear analysis.
• Model and Simulate: Develop analytical models and simulations to evaluate circuit
behavior, subsystem performance and architectural tradeoOs.
• Build and Test: Integrate, characterize and troubleshoot RF hardware in the lab
using vector network analyzers, spectrum analyzers, signal generators and power
meters.
• Solve Complex Problems: Troubleshoot unexpected hardware and system
behavior, identify root causes and implement practical solutions.
• Contribute to the Technical Team: Collaborate across RF, antenna, digital and
signal processing domains to develop a cohesive radar system.
• Drive Hardware Development: Contribute to component selection, prototype
development, design reviews and system level demonstrations.
What We’re Looking For
• Bachelor's or master's degree in Electrical Engineering or a related technical
discipline.
• 2–4 years of relevant experience in RF, microwave, or high frequency hardware
design, development or systems engineering.
• Strong understanding of RF fundamentals, including impedance matching,
transmission lines, S-parameters, gain, noise figure and nonlinear behavior.
• Experience with RF test equipment and hands on hardware characterization.
• Familiarity with RF simulation and analysis tools such as Keysight ADS, AWR
Microwave OOice, Ansys HFSS or equivalent.
• Experience using MATLAB, Python or similar tools for engineering analysis, modeling and data processing.
• Strong analytical and troubleshooting skills, with the ability to move between
detailed circuit behavior and broader system performance.
• A proactive, hands-on approach to engineering and the ability to work
independently while collaborating eOectively with a small team.
• U.S. person: U.S. citizen or green card holder. Required for all candidates (ITAR).
• Clearable: able to obtain a U.S. security clearance.
Bonus Points
• Experience with radar systems or antenna technology.
• Familiarity with transmit/receive architectures, high-power amplifiers, low-noise
receivers or frequency conversion.
• Experience with the radar range equation, sensitivity analysis or RF system link
budgets.
• Exposure to RF PCB design, layout considerations, schematic capture or hardware
prototyping.
• Experience integrating RF hardware with digital electronics, data acquisition or
signal-processing systems.
• Interest in space-based sensing and advanced radar architectures.
Why Join Mithril?
• Make a Direct Impact: Your engineering decisions will influence the design and
performance of the overall system.
• Own Meaningful Technical Challenges: Work across circuit design, RF systems
analysis, and hardware integration rather than being confined to a single narrow
function.
• Build What You Design: Take ideas from simulation and analysis into physical
hardware and system demonstrations.
• Work Closely with Technical Leadership: Collaborate directly with the people
shaping the company's technology and engineering roadmap.
• Grow With the Company: Help build a new engineering organization and expand
your technical responsibilities as the team grows.
