Senior🎓
Top SchoolPierre Cauchois is a founding engineer and systems-oriented software leader with 12 years of experience building reliable cloud and embedded systems, from Freescale/NXP hardware work through Microsoft Azure IoT and Cloudflare production services. He excels at solving hard technical problems quickly while creating infrastructure and processes that scale teams and reduce operational toil — he even embraces “automating himself out of a job” to focus on higher-leverage work. As a former team lead for Azure IoT clients and contributor to high-profile open-source projects like HashiCorp Consul, his contributions emphasize correctness, robust error handling, and thorough testing across distributed systems. Based in Kirkland, WA, he now combines hands-on engineering and early-stage product work as a founding engineer and solo consultant helping startups ship AI/LLM-driven features. Colleagues describe him as a lifelong learner who pairs practical curiosity — he still tinkers with electronics — with a talent for balancing rapid delivery and long-term stability.
