Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Principal Digital (mixed-signal) Architect - **Company:** Lightmatter, Inc. - **Location:** Boston, United States - **Salary:** $217,000.0 - $325,000.0 - **Contract:** Permanent contract - **Skills:** Computer-Aided Design, Computer Engineering, Programming Tools, Digital Architecture, Logic Synthesis of Circuits, Python (Programming Language), MATLAB, Systems Architecture, Data Analytics - **Published:** September 4, 2026 - **Apply:** https://startup.jobs/principal-digital-mixed-signal-architect-lightmatter-company-8365550 ## About the Role * 12+ years and a Masters' degree in Electrical or Computer Engineering * In-depth knowledge of power-efficient digital design flow for high-speed AMS electronics, preferably on photonic communication channels. * Proven track record of delivering successful high-volume silicon in the market. Also, proven understanding of silicon product development flow. * In-depth knowledge of digital circuit design in a high-speed analog/photonic link, including device bring-up, control, and digital signal processing. * Demonstrated strong problem solving skills specifically pertaining to problems that do not have obvious solutions. * Demonstrated strong customer communication, with timely responses and consistently positive feedback, * Understanding of SerDes PCS layer and equalization along with forward error-correction schemes. * Ability and desire to collaborate in a cross-disciplinary team. * Power user of multiple development tools, including CAD tools, SPICE simulators, IBIS-AMI simulators, and general programming languages (e.g., MATLAB or Python). * Willing and able to learn quickly. Self-starter with a "no task is too big or small" attitude. * Innovative and flexible; realizes that a one-size-fits-all approach will not always solve the problem at hand. * Data-driven and analytical; translates numbers into actionable strategies. * Process-oriented and programmatic: builds structure through processes that can be relied upon across the organization. ## Description * Be the digital architecture owner of Lightmatter's Passage product. * Responsible for the digital architecture from initial concept through high-volume production. Work closely with the technical program manager(s) to plan, organize, and execute. * Lead direct collaboration with top tier semiconductor customer(s) throughout the product development process at the system architecture level. * Architect and specify system level digital designs integrating complex AMS and photonic circuits. These circuits include high-speed drivers and receivers, SerDes, ADC/DAC, photonic modulators and detectors. * Collaborate with the product team to develop our future technological and product roadmap. * Work closely with test and validation engineers to validate hardware against simulation prediction. * Actively collaborate with the RTL and DV teams to enable block-level implementation and verification, respectively. * Author, review, and validate architectural specifications. * Identify possible improvements as well as possible pitfalls (including mitigation strategies) around executing the proposed architectures. ## Related Videos - [AI Pair Programming with GitHub Copilot at SAP: Looking Back, Looking Forward!](https://www.wearedevelopers.com/videos/1546-ai-pair-programming-with-github-copilot-at-sap-looking-back-looking-forward) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [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) - [Strange New Worlds: shaping the future of the digital age](https://www.wearedevelopers.com/videos/677-strange-new-worlds-shaping-the-future-of-the-digital-age) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [Exploring AI: Opportunities and Risks in Development](https://www.wearedevelopers.com/videos/1267-exploring-ai-opportunities-and-risks-in-development) ## Related Articles - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Data Science & more: The Lopez dilemma](https://www.wearedevelopers.com/magazine/10-data-science-more-the-lopez-dilemma) - [Everything a Developer Needs to Know About MCP with Neo4j](https://www.wearedevelopers.com/magazine/604-everything-a-developer-needs-to-know-about-mcp-with-neo4j) - [Never delegate the understanding](https://www.wearedevelopers.com/magazine/749-never-delegate-the-understanding) - [Why developer experience matters](https://www.wearedevelopers.com/magazine/514-why-developer-experience-matters) - [What Makes WeAreDevelopers World Congress Different From Every Other Tech Event?](https://www.wearedevelopers.com/magazine/701-what-makes-wearedevelopers-world-congress-different-from-every-other-tech-event)
