What are some common challenges Signal Engineers face when working on railway or transportation projects?

Signal Engineers often encounter challenges such as integrating new signaling systems with legacy infrastructure, adhering to strict safety and regulatory standards, and coordinating with multidisciplinary teams including civil, electrical, and IT engineers. Projects may require balancing tight deadlines with the need for thorough testing and validation of signal systems to ensure passenger and worker safety. Effective communication and adaptability are essential, as priorities can shift quickly due to technical issues or changes in project scope.

What are the key skills and qualifications needed to thrive as a Signal Engineer, and why are they important?

To thrive as a Signal Engineer, you need a solid background in electrical or electronic engineering, strong analytical skills, and a relevant engineering degree or equivalent experience. Familiarity with signaling systems, CAD software, and industry-specific standards such as those from the Institute of Railway Signal Engineers (IRSE) or relevant certifications is typically required. Excellent problem-solving abilities, attention to detail, and effective communication help Signal Engineers collaborate and respond to safety-critical situations. These skills and qualifications are essential to ensure the safe and reliable operation of signaling systems in transportation networks.

What is the difference between Signal Engineer vs Communications Engineer?

AspectSignal EngineerCommunications Engineer
CredentialsBachelor's in Electrical/Electronic Engineering, certifications like IEEEBachelor's in Electrical, Electronics, or Communications Engineering, similar certifications
Work EnvironmentRailways, transit systems, transportation infrastructureTelecom companies, network providers, data centers
Industry UsageTransportation, infrastructure projectsTelecommunications, networking, data transmission
Job FocusDesign and maintenance of signaling systems for safety and efficiencyDesign and implementation of communication systems for data and voice transmission

While both roles require electrical engineering knowledge and similar certifications, Signal Engineers primarily focus on signaling systems in transportation, ensuring safety and operational efficiency. Communications Engineers concentrate on designing and maintaining communication networks for data and voice transmission across various industries.

What are Signal Engineers?

Signal Engineers are professionals who design, install, maintain, and troubleshoot signaling systems that control train movements on railway networks. Their work ensures the safe and efficient operation of trains by managing signals, track circuits, and interlocking systems. Signal Engineers work closely with other railway professionals to implement modern signaling technology and comply with safety standards. They may also be involved in upgrading existing infrastructure or developing new systems for improved reliability and capacity.

Job description

The Role 

We are seeking a Mixed-Signal Behavioral Modeling Engineer to own the creation of behavioral modeling and drive mixed-signal verification methodology from the ground up. You will be part of a collaborative design team developing state-of-the-art mixed-signal SoCs to be hosted on some of the largest, most powerful, rapidly designed and rapidly manufactured satellites ever deployed in space. Your work will directly influence top-level integration and silicon tapeout success. This is a high-impact, technical role with significant ownership across modeling, methodology, verification, and cross-functional alignment with RF, analog, and digital teams.  

Responsibilities 

  • Develop high-level behavioral models for analog and mixed-signal IP (ADCs, DACs, PLLs, LDOs, RF front-end blocks, biasing, amplifiers, etc.). 
  • Create abstracted models using Verilog, Verilog-AMS, or SystemVerilog. 
  • Develop regression infrastructure and mixed-signal testbenches enabling co-simulation (digital + analog). 
  • Integrate AMS models into digital verification environments (UVM-based). 
  • Define and build the mixed-signal verification methodology for top-level SoC and subsystem verification. 
  • Support architectural exploration through early-phase modeling and system-level simulations.  
  • Collaborate with analog/RF designers to capture real-world analog behaviors and map them into accurate behavioral abstractions. 
  • Work with digital and verification teams to ensure seamless integration of AMS models. 
  • Provide modeling and verification insights during architectural reviews, PDR/CDR, and silicon bring-up. 
  • Act as technical leader and subject-matter expert. 

Required Qualifications 

  • M.S. or Ph.D. in Electrical Engineering, Computer Engineering, or related field. 
  • 2+ years of experience in analog/mixed-signal modeling and/or AMS verification. 
  • Hands-on experience with SystemVerilog, Verilog-AMS, wreal/RNM, or equivalent modeling languages. 
  • Strong understanding of analog/mixed-signal circuits (PLLs, LDOs, ADC/DACs, RF/IF paths, clocking, amplifiers). 
  • Experience with mixed-signal co-simulation environments (Cadence AMS Designer, Synopsys VCS AMS, or similar). 

Preferred Qualifications 

  • Experience building AMS verification methodologies from scratch. 
  • Familiarity with UVM-based verification and digital design flows. 
  • Knowledge of signal processing theory, RF system modeling, or communication systems. 
  • Experience with MATLAB/Simulink, Python modeling, or SystemC AMS for high-level architectural modeling. 
  • Experience working in cross-functional, geographically distributed teams.  

Compensation and Benefits:

  • Base salary range for this role is $130,000 - $180,000 + equity in the company
  • Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level
  • Comprehensive benefits package including paid time off, medical/dental/vision/ coverage, life insurance, paid parental leave, and many other perks
