Software Development San Francisco, California 51–200 employees Founded 2020 Privately Held

Highnote operates a distributed, multi-cloud infrastructure (GCP, AWS, Kubernetes) underpinned by Java, Python, and streaming (Kafka, Kinesis, Pub/Sub), with emerging AI tooling (LangChain, CrewAI, AutoGen) integrated into the stack. The hiring mix skews heavily toward senior engineers (12 of 17 open roles) across infrastructure, data, and platform work, while simultaneous investment in technical sales and solution architecture signals scaling toward enterprise go-to-market—a pattern common in B2B fintech moving from founder-led sales to repeatable enterprise motion.
