Job summary

AZX is seeking an ML Engineer to build ML systems inside client environments, owning data discovery, modeling, deployment, and monitoring. You will work across DevOps, infrastructure, and front-end work as the engineering face to clients.

The role requires 5+ years shipping ML to production, strong data engineering skills, and rigorous validation. Remote work is available with a focus on client delivery and measurable KPIs.

Qualifications

• 5+ years of shipping applied machine learning to production — forecasting, detection/classification on time series, survival/reliability modeling, or optimization — with an evaluation you defended to someone whose job depended on it.
• Strong data engineering skills and willingness to use them: you find, clean, join, and profile data yourself at awkward scale, without a dedicated data team.
• Rigorous validation discipline — chronological splits, walk-forward validation, as‑of correctness, and an instinct to be suspicious of a suspiciously good metric.
• Enough software engineering to ship real systems: Python, SQL, tests, Docker, a scheduler, an API or app surface, and monitoring — type‑strict, tested, reviewable code, even in a pod of two.
• Client‑facing capability and the assertion to use it — running discovery, leading demos, and pushing back early and plainly when an ask is wrong, with an alternative already in hand.
• Judgment about when ML is the wrong tool, and the willingness to say so to a client who wants AI regardless.
• Practical fluency with our core stack — Python 3.12+ (pandas/polars/DuckDB, scikit‑learn, statsmodels, gradient boosting), SQL/Postgres (with TimescaleDB/PostGIS for grid work), and time‑series feature engineering and validation.
• Comfort building the surfaces that make a model usable — FastAPI plus enough React/TypeScript to expose results — and deploying it with Docker and basic cloud tooling (Azure/AWS).
• Working fluency with LLMs for the agentic edges of client work (extraction, retrieval) — depth isn't required, but honesty about your actual experience is.
• Bachelor's Degree; Master's is a Plus
• Domain experience in Energy, Utilities, Infrastructure, and Commercial Real Estate is a plus

Responsibilities

• Own the full ML delivery lifecycle: data discovery and cleaning, modeling, evaluation, deployment into the client environment, scheduling, monitoring, and retraining policy.
• Build forecasting and detection models that hold up against real-world data quality issues (late feeds, revised rows, missing labels).
• Backtest and evaluate models honestly enough to stake real operational decisions on them, and defend your precision/recall tradeoffs to the people who bear the cost of false alarms.
• Design systems that distinguish "no prediction" from "wrong prediction", so a missing answer reads differently to the end user than an incorrect one.
• Ship enough product to make the model usable — a FastAPI service, a small React surface, a scheduled job — whatever "usable capability" means for that client.
• Own the measurement story: agree on baselines and KPIs before deployment, instrument for monitoring, and deliver a post-deployment readout with attribution limits clearly stated.
• Maintain client-facing engineering presence and a feedback loop into the platform team — running discovery, working sessions with client IT/data teams, demos, and surfacing the data shapes and failure modes only visible from inside client data.
