System Design Engineer (Senior/Staff/Senior Staff)

We are seeking a highly skilled and experienced System Design Engineer (Modelling & Architecture) to play a key role in architecting and validating high-performance serial links and data-converter systems for our state-of-the-art chiplet solutions. You will directly shape the system architecture and behavioural models of customer-facing IP, driving early design decisions, performance exploration, and architectural trade-offs across SerDes, ADC/DAC, and PLL subsystems., * System Architecture & Modelling: Define and develop system-level architectures and behavioural models for high-speed links and mixed-signal subsystems, including SerDes, ADCs, DACs, and PLLs.

• High-Level Modelling (MATLAB / Simulink): Build and maintain accurate system models in MATLAB/Simulink to evaluate performance, explore trade-offs, and guide design decisions across noise, jitter, bandwidth, and power.
• SerDes System Modelling: Develop end-to-end link models including channel, equalization (FFE/DFE), jitter budgets, and clock and data recovery (CDR) behaviour.
• ADC/DAC Modelling & Calibration: Model data converter architectures and implement advanced calibration algorithms (e.g. background calibration, mismatch correction, linearity enhancement), assessing system-level impact on ENOB, SFDR, and dynamic performance.
• PLL & CDR Behavioural Modelling: Develop behavioural models for PLLs and CDR loops, including phase noise, jitter transfer, loop dynamics, and locking behaviour.
• Cross-Domain Collaboration: Work closely with circuit designers, digital teams, and system architects to translate system requirements into block-level specifications and ensure model-to-silicon correlation.
• Performance Analysis & Optimization: Analyze system performance and identify architectural improvements across latency, power, robustness, and scalability.
• Verification Strategy Support: Contribute to system-level verification strategies and support correlation between behavioural models, RTL, and silicon measurements.
• Technology & Competitive Awareness: Stay current with industry trends in high-speed interfaces, data converters, and chiplet-based architectures, including benchmarking against competitive solutions.
• Documentation & Knowledge Transfer: Produce clear and structured documentation of models, assumptions, and architectural decisions to enable efficient collaboration and reuse., We're a fully remote team of around 25 people distributed across the UK, Armenia, Italy, the US, Estonia, India, and beyond. We believe great talent is everywhere!
• Our values are our north star: We Grow Together, We Win Together. Excellence Builds Relationships. Trust Is Our Currency. Results Matter, but People Create Them.
• Connected, even remotely: We invest intentionally in staying connected through regular all-hands, 1:1s, technical reviews, and informal coffee chats, so collaboration feels natural and human despite the distance.
• High ownership, real impact: Everyone contributes directly to customer-facing IP. Your work doesn't disappear into layers of management - it ships.
• How we work: We move fast but thoughtfully, communicate openly, and balance autonomy with support. Technical decisions are debated openly and grounded in data, trade-offs, and first-principles thinking.

WHY JOIN US

• Remote-first flexibility - work from anywhere, with flexible hours
• Equipment & setup - we'll provide the tools you need to succeed
• High-impact projects - design real analog IP used in customer silicon
• Supportive team culture - a dedicated manager and a team of colleagues ready to help
• Competitive, transparent compensation - adjusted for your location and engagement model
• Learning & growth - AI-DLP sessions, technical deep dives, and peer-led knowledge sharing that build both technical depth and system-level perspective

This role is ideal for engineers with strong modelling expertise and system-level thinking, who enjoy bridging architecture and implementation in a fast-moving, high-impact environment., Must-have Technical Skills:

• M.S. or Ph.D. in Electrical Engineering or related field
• 8-12+ years of experience in system design and modelling of high-speed or mixed-signal systems
• Strong expertise in SerDes system architecture and modelling
• Proven experience with MATLAB and Simulink for system-level modelling
• Solid understanding of ADC/DAC architectures and calibration techniques
• Experience in PLL and CDR modelling, including jitter and loop dynamics
• Good understanding of mixed-signal implementation constraints in advanced CMOS nodes
• Familiarity with link-level metrics: BER, eye diagrams, jitter budgets, equalization techniques
• Ability to bridge system modelling with circuit and RTL implementation

Nice-to-have:

• Experience with UCIe or chiplet-based architectures
• Exposure to behavioural modelling in SystemVerilog or real-number modelling (RNM)
• Prior silicon correlation or lab validation experience

Soft & Professional Skills:

• Clear, structured communication in professional English
• Strong system-level thinking and abstraction capability
• Collaborative, cross-functional mindset
• Ability to mentor and guide junior engineers
• High ownership and accountability
• Curious and proactive approach to problem-solving, 2. Technical Interview (90 min) - fundamentals, reasoning, and problem-solving

3. Presentation (60 min) - short presentation on a topic of your choice, to assess clarity, structure, and confidence in presenting your work
4. HR & Culture Call (45 min) - values, collaboration style, and ways of working
5. Offer & Next Steps (30 min) - offer walkthrough, alignment on details, and next steps, discussed in a final call with the founder.

If you don't meet every requirement but feel excited about the role, apply anyway. We value curiosity, integrity, and potential as much as experience.
