This is an agentic engineering role. You will direct fleets of coding agents-Claude Code and Codex-and orchestrate them to amplify your output. Your job is to architect, direct, review, and ship at a scale no individual coder reaches alone. We operate agent-first. The mandate extends beyond automating output generation for our customer base. We are driving toward full automation of customer onboarding as well-turning what is today human-intensive integration and ramp work into agent-executed pipelines. Hybrid only with 3 days in office weekly. New York City (Manhattan Financial District), Oakland, or Austin. What you'll do * Orchestrate agent fleets to design, build, and ship data infrastructure that ingests, sanitizes, and normalizes a broad range of medical data-electronic health records, journals, established medical ontologies, crowd-sourced labeling, and other human inputs. * Build infrastructure that scales both data ingest and large-scale cloud-based machine learning. * Build performant, expressive interfaces to that data. * Drive automation of customer onboarding-replace manual integration and ramp work with agent-executed systems. * Operate as a force multiplier: set technical direction, direct humans and agents toward outcomes, and own delivery. ## Related Videos - [Alibaba Big Data and Machine Learning Technology](https://www.wearedevelopers.com/videos/37-alibaba-big-data-and-machine-learning-technology) - [PySpark - Combining Machine Learning & Big Data](https://www.wearedevelopers.com/videos/44-pyspark-combining-machine-learning-big-data) - [Hacking AI at the Edge of the Indian Ocean](https://www.wearedevelopers.com/videos/100177-hacking-ai-at-the-edge-of-the-indian-ocean) - [Why and when should we consider Stream Processing frameworks in our solutions](https://www.wearedevelopers.com/videos/1085-why-and-when-should-we-consider-stream-processing-frameworks-in-our-solutions) - [Modern Data Architectures need Software Engineering](https://www.wearedevelopers.com/videos/1030-modern-data-architectures-need-software-engineering) - [Data Analytics with Microsoft Fabric: End-to-End Use Case with Data Agents](https://www.wearedevelopers.com/videos/1547-data-analytics-with-microsoft-fabric-end-to-end-use-case-with-data-agents) ## Related Articles - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Top Big Data Technologies That You Need to Know](https://www.wearedevelopers.com/magazine/108-top-big-data-technologies-that-you-need-to-know) - [How Much FAANG Companies Actually Pay Software Engineers in 2025](https://www.wearedevelopers.com/magazine/230-how-much-faang-companies-actually-pay-software-engineers-in-2025) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [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) - [Is Software Engineering Over-Saturated?](https://www.wearedevelopers.com/magazine/418-is-software-engineering-over-saturated)
