Job description

Job Description

Are you driven by curiosity, energized by complex challenges, and motivated to dissect the unknown? Join a cutting‑edge team where your expertise directly shapes mission outcomes and national security. 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 is seeking 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 for this position will contribute to the team by utilizing industry‑standard functional verification tools (e.g., Questa, VCS, Verdi), logical equivalence tools (e.g., OneSpin 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.

Level 2 salary range: 90,000‑95,000

Level 3 salary range : 120,000‑130,000

Level 4 salary range : 160,000‑175,000

Level 5 salary range : 185,000‑190,000

Candidates will develop models, transactors, stimuli, monitors, and test benches for simulating and uncovering hidden behaviors in gate‑level digital netlists. Candidates will be expected to produce clear documentation and test cases demonstrating identified bugs or deviations from the specification. Effective collaboration with teammates to produce cohesive results and create improved processes is required.

Minimum Qualifications

Level 2: 2 years relevant experience with Bachelors in related field; 0 years experience with Masters in related field; or High School Diploma or equivalent and 6 years relevant experience.

Level 3 : 5 years relevant experience with Bachelors in related field; 3 years relevant experience with Masters in related field; 0 years experience with PhD or Juris Doctorate in related field; or High School Diploma or equivalent and 9 years relevant experience.

Level 4 : 9 years relevant experience with Bachelors in related field; 7 years relevant experience with Masters in related field; 4 years relevant experience with PhD or Juris Doctorate in realted field; or High School Diploma or equivalent and 13 years relevant experience.

Level 5 : 15 years relevant experience with Bachelors in related field; 13 years relevant experience with Masters in related field; 10 years relevant experience with PhD or Juris Doctorate in related field; or High School Diploma or equivalent and 19 years relevant experience.

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: SystemVerilog, 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 for maintaining, sharing, and deploying code: Perforce, git, SVN, etc.

Familiarity with debugging and isolating issues with gate‑level netlists

Preferred Requirements

• 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., OneSpin 360‑EC, ESP, Conformal EC)


• Experience with formal ABV

Benefits

We offer competitive benefits such as best‑in‑class medical, dental and vision plan choices; wellness resources; employee assistance programs; Savings Plan Options (401(k)); financial planning tools, life insurance; employee discounts; paid holidays and paid time off; tuition reimbursement; as well as early childhood and post‑secondary education scholarships.
