Job summary

AZX is seeking an ML Engineer who builds ML systems directly inside client environments. Your work starts with the client's data spread across multiple systems, and ends with a model running on a schedule inside their environment.

You will wear many hats as part of a small team (DevOps, infrastructure, frontend/backend) because you are the engineering face of AZX to your client, delivering measurable impact.

Qualifications

• 5+ years shipping ML to production with defendable evaluation.
• Strong data engineering skills to handle large data without a dedicated team.
• Rigorous validation: chrono splits, walk-forward validation, as-of correctness.
• Software engineering: Python, SQL, tests, Docker, scheduler, API surface, monitoring.
• Client-facing: run discovery, demos, push back clearly with alternatives.
• Judgment about ML applicability to client problems.
• Fluency with Python 3.12+ stack and time-series tooling.
• Ability to expose results via FastAPI and React/TS, with Docker and cloud basics.
• Active collaboration with data IT teams and clients.
• Domain experience in Energy/Utilities/Real Estate is a plus.

Responsibilities

• Own the ML delivery lifecycle from data discovery to deployment in client environments.
• Build forecasting and detection models robust to real-world data quality issues.
• Backtest and defend model accuracy and precision/recall tradeoffs.
• Design systems to distinguish no prediction from wrong prediction for end users.
• Ship usable capabilities: FastAPI service, React surface, scheduled jobs.
• Measure baselines and KPIs, instrument monitoring, and provide post-deployment readouts.
• Maintain client-facing engineering presence with discovery and demos.

Job description

Our mission is to accelerate positive impact in critical industries through AI transformation. We specialize in physics-informed ML and enterprise AI solutions that directly address climate and sustainability challenges.

We're growing quickly and already work with category-leaders in real estate (CBRE), energy (LevelTen Energy), logistics (Flexe) and utilities.

We bootstrapped profitably for our first year and are now backed by leading investors focused on AI, climate and energy.

We work on challenges in clean energy, decarbonization, climate risk, energy systems, and global economics. We're building our company for long-term success and aim to create the ultimate place to work for those passionate about AI and making a positive impact.

We work on challenges in clean energy, decarbonization, climate risk, energy systems, and global economics. We're building our company for long-term success and aim to create the ultimate place to work for those passionate about AI and making a positive impact.

About This Role

We are seeking an ML Engineer who builds ML systems directly inside client environments. Your job starts with the client's actual data spread across multiple systems, and ends with a model running on a schedule inside their environment. You will bring a strong area of expertise, but expect to wear many hats as part of a small team (some DevOps, some infrastructure, some front end and back end) because you are the engineering face of AZX to your client.

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.

Additional Information

• Must be able to travel 2x/year for company summits
• Applicants must be currently authorized to work in the United States on a full-time basis.
• We are unable to sponsor or take over sponsorship of employment visas at this time.
• Please note that our interview process includes a written take-home assignment followed by a live two-hour technical session with our engineering team, so if that format isn't a good fit, we'd ask that you not apply.
• Please only apply to a maximum of 2 roles at a time; any applicants who apply to more than 2 roles within a 6 month period will automatically be disqualified.

Required 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.

Benefits & Perks

Why AZX!

• Be part of a fast-growing, profitable, mission-driven company with industry-leading clients tackling the massive opportunity of AI transformation in critical industries.
• Competitive early-stage startup compensation (based on capabilities, experience, and location)
• Bonus eligibility
• Health insurance with meaningful coverage for dependents
• Flexible paid time off
• Equity
• Fully remote culture with a cluster of teammates in Seattle
