Job description

Job Title: Contract Signal Integrity / Power Integrity Engineer (UK Nationals Only)

Location: 100% Remote (UK-Based)

Contract Duration: 6–12 Months
Start Date: ASAP
Clearance Requirement: UK Nationals Only (Due to project sensitivity)
Overview:
We are seeking an experienced Signal Integrity / Power Integrity Engineer for a long-term contract role supporting advanced hardware development projects within a high-reliability environment. This role is fully remote but restricted to UK nationals due to the nature of the work and data security requirements.
Key Responsibilities:

-Perform advanced Signal Integrity (SI) and Power Integrity (PI) analysis across high-speed digital designs.
-Model and simulate high-speed interconnects, PCB stack-ups, power delivery networks (PDNs), and associated parasitics.
-Provide design recommendations to ensure signal quality, noise margin, and power stability are within specification.
-Work closely with PCB layout teams, hardware designers, and systems engineers to optimize designs from concept to production.
-Validate simulation models with lab measurements and assist in root cause analysis of SI/PI-related issues.
-Document analysis results, methodologies, and recommendations for both internal teams and customer reporting.Required Skills and Experience:

-Proven experience in SI/PI engineering within high-speed digital system environments.
-Strong proficiency with industry-standard simulation tools such as:

-Ansys SIwave, Keysight ADS, Cadence Sigrity, or Mentor HyperLynx
-In-depth understanding of PCB design and manufacturing constraints affecting signal and power integrity.
-Solid knowledge of transmission line theory, impedance matching, crosstalk, jitter, PDN resonance, and decoupling strategies.
-Hands-on experience with simulation-to-lab correlation using oscilloscopes, VNAs, TDRs, and probes.
-Ability to work independently in a remote setting, collaborating virtually with multi-disciplinary teams.Preferred Qualifications:

-Degree in Electrical Engineering or a related field.
-Experience working in sectors such as aerospace, defence, telecommunications, or high-performance computing.
-Familiarity with DDR, PCIe, Ethernet, or SerDes interfaces at multi-Gbps rates.Additional Information:

-This is a UK-based remote role; applicants must be UK nationals to be considered.
-Engagement is expected to last between 6 and 12 months, with potential for extension based on project scope.
