Flowcode
📍 New York• $200K – $225K/yr
26 days ago

Head of Talent Location: New York, NY, onsite 5 days per week Role type: Full time Reports to: President Why this role exists now Flowcode builds the infrastructure that turns real world touchpoints into measurable, actionable first party IDs, enabling F500 brands to personalize consumer experiences at scale. One of Flowcode’s founding principles is “the product is the team, and the team is the product.” We treat hiring with the same level of rigor we apply to product development. We have an extremely high hiring bar (the “pinhole process”), which to date we have applied by brute force. Our CEO, President and our executive team each personally read resumes, sit on interview loops, and close candidates. It works. But it also means our hiring speed is capped by the calendars of the ten busiest people in the company, and our pipeline stops the moment one promising candidate appears. The same principle applies after someone signs. The people we fight to hire need to be onboarded, developed, managed well and retained. Today those systems are spread across too many owners. This role brings them under one leader. We are not hiring a coordinator, a req-filler, or an HR generalist who also does some recruiting. We are hiring the person who owns the talent bar, the pipeline and the close, and who owns the People foundation that makes great hires stay great. You are relentless in your proactive pursuit of top 1% talent, and you never consider the pipeline “good enough.” You are just as relentless about making Flowcode a place where exceptional people do their best work and grow. What you own Talent Acquisition The talent bar: You define, in writing, what "top 1%" means for each function at Flowcode, with calibrated scorecards and interview questions — and you hold the line when a hiring manager, or anyone else at the company, including the executive team, wants an exception. An always-on pipeline: You do not just open requisitions when a seat empties. You have named, warm, map

What you’ll do Partner with medical image reconstruction scientists / engineers to build ML components that improve reconstruction quality, speed, robustness, or quantitative accuracy. Define training/evaluation pipelines, datasets, and metrics that map to user needs and design requirements. Productionize models: inference performance, reproducibility, monitoring for drift/regressions, and safe fallbacks. Collaborate on hybrid algorithms, incorporating physics and learned priors, denoisers, learned regularizers, and quality estimation. Help build tooling for rapid experimentation as well as rigorous verification of algorithm changes. What we’re looking for Strong applied ML experience plus comfort with signal processing / imaging or adjacent domains. Ability to move fluidly between research prototypes and production-quality systems. Strong evaluation discipline: metrics, ablations, data leakage avoidance, and reproducibility. A demonstrated track record of applying ML to physics-based or inverse problems (i.e., shipped projects, a portfolio, or publications.) Useful experience ML for imaging/inverse problems (or adjacent) with strong evaluation discipline and comfort with GPU performance constraints. Pragmatic production mindset: reproducible training/inference, regression testing, and safe deployment in high-stakes contexts. A background in computational physics or scientific computing. Leverage ML-based methods such as PiNNs and Neural Operators to solve partial differential equations arising in ultrasound simulation and imaging. Experience in Agentic-SciML is a plus. Hands-on experience with data curation for ML: building datasets from messy, real-world sources, defining ground truth, and managing labeling or simulation pipelines. Background in data assimilation: combining observations with physics-based models (Kalman filtering, variational methods, ensemble approaches, or learned variants).
