We develop advanced hardware security technologies designed to address emerging threats in post-quantum computing environments, working at the intersection of cryptography, semiconductor engineering, and secure system architecture.

We are building a team of highly skilled engineers passionate about cutting-edge FPGA and ASIC development, secure hardware design, and innovative defense-grade technologies.

Position: ASIC Back-End / Physical Design Engineer (multiple)

Compensation: 22,000–29,000 PLN gross/month

Employment type: Polish employment contract

Resquant is looking for highly skilled ASIC Back-End / Physical Design Engineers for various positions. This is a great opportunity to join a rapidly growing startup at an early stage, working on the latest trends in chip security and cryptography. The project targets the GlobalFoundries 22 nm FDX (22FDX) FD-SOI platform.

Main responsibilities:

• Driving the full physical implementation flow — floorplanning, placement, clock tree synthesis (CTS), and routing — for quantum-resistant cryptographic processors.

• Performing timing closure and static timing analysis (STA) signoff across multiple corners and modes (setup/hold).

• Power planning and analysis, including IR-drop and electromigration (EM) checks.

• Implementing low-power architectures: power domains, level shifters, isolation cells, and the body-bias distribution network required for Adaptive Body Bias (ABB) on GF 22FDX FD-SOI.

• Handling synthesis-to-layout handoff, ECOs, and tapeout preparation in cooperation with the foundry (GlobalFoundries).

• Participation in certification and technical documentation development.

Our requirements:

• Bachelor’s or master’s degree in Electrical Engineering, Computer Engineering, or a related field.

• 5+ years (Mid-level) or 8+ years (Senior-level) of hands-on experience in ASIC back-end / physical design.

• Experience with place-and-route tools (e.g. Innovus, IC Compiler II / Fusion Compiler).

• Strong static timing analysis skills and signoff experience (e.g. PrimeTime, Tempus).

• Experience with physical verification tools (e.g. Calibre, IC Validator, Pegasus) for DRC/LVS.

• Proficiency in floorplanning, clock tree synthesis, power planning, and routing.

• Knowledge of low-power implementation and power intent (UPF/CPF).

• Understanding of the full ASIC design flow and front-end / back-end interaction.

• Familiarity with high-speed interfaces and protocols such as PCIe, Ethernet, and AXI.

• Ability to work independently or strong cooperation skills to work within a cross-functional team.

• Strong problem-solving and analytical thinking skills.

• EU citizenship.

• Candidates must be eligible for employment under a Polish employment contract (UoP).

Preferred candidates with:

• Hands-on experience with the GlobalFoundries 22FDX / FD-SOI process technology.

• Experience with Adaptive Body Bias (ABB) techniques.

• Proven track record in low-power optimization.

• Experience with True Random Number Generators (TRNG) or Physically Unclonable Functions (PUF).

• Experience with side-channel attacks and countermeasures.

• EU/NATO security clearance.

What do we offer:

• Full-time Senior and Mid-level positions

• Salary range: 22,000–29,000 PLN gross/month, depending on experience and seniority.

• Employment under an employment contract

• Participation in projects aimed at providing a backbone for chip security for dual-use markets.

• Flexible working hours.

• Ability to work remotely (Hybrid/Full).

• Equity options.

• Broad technical ownership.

• Innovation and cutting-edge projects.

• Opportunity to attend closed events with military representatives.
