Leadership Mindset at HII – Mission Technologies

Leadership at HII is a mindset, not a title. Through our Leadership Capability Framework, we define how every employee grows, leads, and contributes—regardless of role. We look for candidates who want to grow in alignment with these capabilities:

• Know & Grow Your People – Commit to learning and supporting team success.
• Build Relationships – Communicate openly, collaborate well, and build trust.
• Take Ownership – Deliver on commitments and take pride in your work.
• Customer First – Focus on the mission and those we serve.
• Shape the Future – Bring ideas, curiosity, and continuous improvement.
• Act with Urgency – Take initiative and follow through with purpose.

We’re looking for engineers who excel at uncovering how systems work (and why), thrive in an environment where innovation moves fast and the stakes are high. If you enjoy pushing boundaries, experimenting with new approaches, and delivering solutions that make a measurable impact—this is the role for you.

HII Mission Technologies seeks out‑of‑the‑box thinkers who can uncover difficult‑to‑activate corner‑case bugs and vulnerabilities in the gate‑level netlists of FPGA and ASIC designs. Candidates will utilize industry‑standard functional verification tools (e.g., Questa, VCS, Verdi), logical equivalence tools (e.g., One Spin 360EC), and proprietary software tools to verify design function and integrity. Common verification targets include embedded processors, DSPs, filters, transceivers, data links, systems‑on‑chip, and decoders.

Experience in the cybersecurity, electronic warfare, encryption, radar, and/or satellite communications domains is a plus.

• Develop models, transactors, stimuli, monitors, and test benches for simulating and uncovering hidden behaviors in gate‑level digital netlists.
• Produce clear documentation and test cases demonstrating identified bugs or deviations from the specification.
• Effectively collaborate with teammates to produce cohesive results and create improved processes.

• US Citizenship
• Willingness to obtain a Top‑Secret security clearance
• Degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field
• Experience with modern digital verification and modeling languages:
  System Verilog, SystemC, C/C++, Matlab, etc.
• Directed, constrained‑random, and assertion‑based verification techniques at the gate, interface, and transaction levels
• Experience with modern, commercial‑grade, functional simulators (e.g., Xcelium, Incisive, Questa, VCS, Riviera‑Pro, etc.)
• Writing scripts for batched verification tasks:
  Python, Bash, Tcl, make files
• Revision control systems:
  Perforce, git, SVN, etc.
• Familiarity with debugging and isolating issues with gate‑level netlists
• Relevant experience levels:
  Level 2 – 2 years, Level 3 – 5 years, Level 4 – 9 years, Level 5 – 15 years (educational background and experience may adjust these ranges).

• Familiarity with object‑oriented, embedded, assembly, or machine‑code programming
• Software or hardware reverse‑engineering (e.g., IDA Pro, Ghidra)
• FPGA design or verification
• Active Top Secret security clearance
• Familiarity with testing and verification techniques for IC trust, assurance, or security
• Experience with logical equivalence checkers (e.g., One Spin 360‑EC, ESP, Conformal EC)
• Experience with formal ABV
