This role focuses on the digital architecture that connects real-world analog measurements to control-loop decisions: ADC interfaces, ADC controllers, front-end filtering, digital signal processing, telemetry paths, emulation models, timing behavior, fixed-point implementation, and hardware/firmware interface definition. The successful candidate will work closely with systems, digital design, firmware, verification, validation, applications, and analog design teams to translate product requirements into executable architecture, emulation-ready models, RTL-facing specifications, and silicon-validation evidence. This is not a traditional analog design role; it is a digital systems architecture role for mixed-signal power products. WHY THIS ROLE MATTERS + Own the digital mixed-signal architecture between sensed power-rail behavior and control-loop action. + Define reusable front-end DSP, ADC-control, emulation, and observability patterns for advanced digital power products. + Help product teams converge faster by making mixed-signal behavior executable, measurable, and traceable from model to RTL to silicon., + Define digital mixed-signal system architecture for digital multiphase power controllers and related power management products. + Architect front-end digital signal-processing paths used to filter, condition, scale, decimate, observe, and route sensed voltage and current information into control-loop, telemetry, protection, and diagnostic functions. + Define ADC interface behavior, ADC controller requirements, sampling relationships, data-valid timing, channel sequencing, calibration hooks, latency budgets, saturation behavior, quantization expectations, and error-handling requirements. + Develop executable models and emulation-oriented representations that allow system behavior to be explored before RTL and silicon are complete. + Translate system and control-loop requirements into RTL-facing specifications, fixed-point formats, datapath constraints, register behavior, firmware interfaces, and validation requirements. + Collaborate with analog design experts on ADC and sensing assumptions while focusing ownership on the digital architecture, control data path, emulation behavior, and system-level integration. + Work with firmware teams to define observability, debug access, telemetry behavior, configuration flows, and bring-up hooks needed for characterization and customer support. + Partner with verification and validation teams to define reference scenarios, pass/fail criteria, correlation expectations, coverage targets, and structured evidence for architectural decisions. + Analyze tradeoffs across loop performance, latency, noise sensitivity, resolution, dynamic range, power, area, configurability, implementation complexity, and customer-visible behavior. + Document architecture clearly for cross-functional execution teams, including assumptions, interface contracts, model behavior, limits, corner cases, and validation expectations. ## Related Videos - [How to Domain Model – An example from manufacturing](https://www.wearedevelopers.com/videos/742-how-to-domain-model-an-example-from-manufacturing) - [Thinking Differently - How to Make Money from Cyber Attacks & Cheats](https://www.wearedevelopers.com/videos/745-thinking-differently-how-to-make-money-from-cyber-attacks-cheats) - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Playing Pong on a shoulder press machine](https://www.wearedevelopers.com/videos/100140-playing-pong-on-a-shoulder-press-machine) - [Software stack under and over the hood of the fastest accelerating car in the world](https://www.wearedevelopers.com/videos/221-software-stack-under-and-over-the-hood-of-the-fastest-accelerating-car-in-the-world) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) ## Related Articles - [How software is steering vehicle technology](https://www.wearedevelopers.com/magazine/515-how-software-is-steering-vehicle-technology) - [Résumé-Driven Development: How IT trends affect the job market for software developers](https://www.wearedevelopers.com/magazine/59-resume-driven-development-how-it-trends-affect-the-job-market-for-software-developers) - [Why Event-Driven Architecture Isn’t About Speed (and When You Actually Need It)](https://www.wearedevelopers.com/magazine/745-why-event-driven-architecture-isn-t-about-speed-and-when-you-actually-need-it) - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [From developer to manager – what does it take to become an engineering manager?](https://www.wearedevelopers.com/magazine/42-from-developer-to-manager-what-does-it-take-to-become-an-engineering-manager) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
