Develop production-grade communication frameworks and applications, optimize performance and scalability, and collaborate with networking chip design teams on hardware/software co-design.

Perform GNC engineering including non-linear 6DOF simulation and linear MATLAB analysis, embedded flight control software design/code/test, and flight test support (pre-flight predictions, real-time support, post-flight analysis). Develop or improve G&C methods, support proposals and new projects, and perform control law development, stability/handling analyses, and parameter identification.

Lead integration of avionics/payload subsystems, resolving integration issues with IPTs and suppliers. Validate sensor performance, use RF test equipment, and support system-level testing. Work full-time on-site, collaborate with lab teams, and comply with required Top Secret/SCI/SAP clearances; travel up to 25% may be required.

Develop and optimize ultra-low-latency algorithmic trading and execution engines for cryptocurrency markets. Collaborate with quantitative researchers and traders to implement and maintain high-performance HFT systems, troubleshoot production issues, and continually improve system latency and reliability.

Design, test, and optimize electromechanical systems and motor control firmware. Specify and tune BLDC motors, harmonic drives, and gearboxes. Implement FOC firmware on microcontrollers and integrate industrial communications (EtherCAT, CAN). Collaborate with mechanical engineers on joint design and thermal management to improve efficiency and torque density.

Develop and evaluate high-resolution tactile sensing and dexterous manipulation systems by processing tactile and force-torque data, implementing slip-detection and compliant control, training multi-fingered grasping policies, integrating solutions into robotic platforms, and conducting experiments to validate performance.

Design, build, and operate Restate Cloud and BYOC deployments across multi-tenant SaaS and on-prem environments. Implement IaC and cloud orchestration for Kubernetes-based stateful workloads, ensure reliability and observability (SLOs, metrics, traces, logs, runbooks), automate fleet scaling, and participate in on-call rotations supporting production operations.

Develop and maintain web and desktop applications using .NET technologies. Requires strong programming skills, experience with databases, and project management.

Design high-performance C++ libraries for automated PCB design challenges, mentoring peers and shaping technical direction while collaborating with experts in various fields.

Design and implement a video processing engine, develop a cross-platform rendering engine, integrate systems, and optimize performance while collaborating with other engineers.
