accreditation.\nWhat you'll do\n- Launch hosted language and speech services inside a secured cloud boundary and optimize them for response quality, speed and spend.\n- Relocate retrieval and modeling workflows to approved cloud services, keeping all data inside the accredited perimeter.\n- Create assessments that measure correctness, source grounding and refusal handling, and share the findings with the client.\n- Keep records of model releases, instruction templates, vetted container images and data origins to support the security authorization package.\n- Add speech input to the product using a cloud speech service within the compliant boundary.\n- Set up permissions and activity logging for the retrieval layer, collaborating with a full stack engineer.\nRequirements\nWhat we're

setting, spanning serving, testing and data flows.\n- A minimum of one year working on builds inside a Department of Defense or US federal IL5 setting.\n- Seven-plus years of experience shipping and operating machine learning models that handle live user load.\n- Day-to-day accountability for running model services, covering release tracking, adapting models, protecting sensitive data and keeping audit trails.\n- Substantial familiarity with cloud-hosted large language models, retrieval pipelines built on embedding search, and structured model testing.\n- Track record of taking a product or model from concept to launch at a venture-backed startup or a large technology firm.\n- Expertise in cloud-based AI platforms, with a major public cloud preferred and AWS or GCP also valued.\n- A bachelor's degree in computer science or a STEM-related field.\nBonus points\n- Prior work in a regulated or public-facing sector, such as public service, defense, banking or care delivery.\n- Past
