At Agero, the Machine Learning Engineer role—often positioned as a Principal Optimization and Machine Learning Engineer—is a pivotal technical position that sits at the intersection of data science, operations research, and large-scale software engineering. You will be joining a team responsible for the next-generation Dispatch System, a critical platform powered by Swoop that manages millions of roadside events annually. This system determines which service provider gets which job, when, and why, directly impacting the safety of stranded drivers and the efficiency of the network.

This role goes beyond standard predictive modeling. You are expected to fuse short-term and long-term horizon optimizers to solve complex logistical problems. Your work will involve architecting end-to-end Python services, building prediction models using techniques like gradient boosting and deep learning, and integrating them into constrained optimization frameworks. You will be instrumental in rethinking the vehicle ownership experience by transforming manual dispatch processes into digital, transparent, and connected solutions.

For Agero, this position is strategic. You are not just optimizing a metric in a vacuum; you are balancing cost efficiency against service-level agreements (SLAs) and Net Promoter Scores (NPS). The solutions you build will be deployed on AWS and must operate in real-time, handling the complexity of a massive B2B white-label network that serves over 150 million vehicle coverage points.

Preparing for an engineering role at Agero requires a shift in mindset from pure algorithm design to applied, high-stakes problem solving. You should approach your preparation with the understanding that Agero values "scientific rigor" applied to "operational excellence."

Key Evaluation Criteria

Hybrid Expertise (ML + Optimization) – Agero specifically looks for candidates who bridge the gap between modern Machine Learning (XGBoost, PyTorch) and Operations Research (Mixed Integer Programming, Linear Optimization). You must demonstrate how you use prediction models to feed into decision-making frameworks.

Production Engineering – Theoretical knowledge is not enough. You will be evaluated on your ability to "architect and ship." This means demonstrating expert-level Python skills, familiarity with cloud-native pipelines (AWS), and the ability to design systems that are robust, scalable, and maintainable.

Domain Logic & Simulation – The ability to translate business objectives into mathematically rigorous experiments is essential. Interviewers will assess your capability to run time-horizon simulations and quantify trade-offs between conflicting KPIs, such as operational cost versus customer satisfaction.

Communication & Leadership – As a senior or principal contributor, you are expected to partner with Product and Ops teams. You will be evaluated on your ability to explain complex mathematical concepts to non-technical stakeholders and your potential to mentor junior engineers.

The interview process for the Machine Learning Engineer role at Agero is thorough and designed to test both your coding proficiency and your ability to solve ambiguous logistical problems. Generally, the process begins with a recruiter screen to align on your background and interest in the roadside assistance domain. This is followed by a technical screen, which typically focuses on coding fundamentals and a high-level discussion of your past projects involving optimization or ML systems.

Successful candidates move to a comprehensive loop, often involving a mix of technical deep dives and behavioral assessments. You should expect sessions dedicated to system design, where you may be asked to architect a dispatch service or a real-time decision engine. There is often a specific focus on "Optimization" or "Operations Research" case studies, distinguishing this process from standard ML interviews. The team values candidates who can discuss the end-to-end lifecycle of a model, from feature engineering in SQL to deployment via SageMaker or Airflow.

Throughout the process, Agero places a strong emphasis on culture and mission alignment. They are looking for "passionate people" who care about the driver experience. You will likely meet with cross-functional partners (Product or Data Engineering) to ensure you can collaborate effectively in a hybrid or remote environment.

The timeline above illustrates the typical progression from application to offer. Use this to pace your preparation; ensure your coding skills are sharp for the early screens, then shift your focus to system design and optimization theory for the final rounds.

The following areas represent the core technical pillars for this role. Based on the job description and the nature of Agero's business, you must be prepared to discuss these topics in depth.

Mathematical Optimization & Operations Research

This is a distinguishing feature of the Agero interview. Unlike general ML roles, you are expected to understand how to make decisions under constraints. You need to show that you can take the output of a probability model and use it to drive a logistical action.

Be ready to go over:

• Constrained Optimization – Formulating problems using Mixed Integer Programming (MIP) or Linear Programming (LP).
• Tools & Libraries – Experience with OR-Tools, Gurobi, or CPLEX.
• Stochastic Optimization – How to handle uncertainty in your objective functions (e.g., uncertain traffic or provider availability).
• Advanced concepts – Monte-Carlo tree search, multi-agent simulation, or hierarchical Reinforcement Learning (RL).

Example questions or scenarios:

• "How would you assign 1,000 roadside requests to a fleet of 500 tow trucks to minimize total mileage while meeting ETA SLAs?"
• "Explain the difference between a heuristic approach and an exact solver for a Vehicle Routing Problem (VRP)."
• "How do you incorporate a probability of failure (predicted by an ML model) into a linear optimization constraint?"

Applied Machine Learning & Modeling

While optimization drives the decision, ML drives the intelligence. You must demonstrate deep knowledge of predictive modeling, specifically regarding time-series or tabular data relevant to logistics.

Be ready to go over:

• Modern ML Algorithms – Gradient-boosting machines (XGBoost, LightGBM) and Deep Learning (PyTorch, Transformers).
• Feature Engineering – Handling geospatial data, timestamps, and categorical variables in a dispatch context.
• Evaluation Metrics – Beyond accuracy/AUC; discuss business metrics like cost-per-dispatch or ETA deviation.

Example questions or scenarios:

• "How would you build a model to predict the arrival time of a tow truck provider?"
• "Describe how you would handle high-cardinality categorical features in a gradient boosting model."
• "How do you prevent data leakage when training a model on historical dispatch data?"

System Design & MLOps

Agero requires "ownership of production systems." You will be tested on your ability to build the infrastructure that supports your models.

Be ready to go over:

• Cloud-Native Architecture – Designing pipelines on AWS using services like SageMaker and Airflow.
• Data Engineering – Strong SQL skills, feature store design, and data quality checks.
• Deployment Patterns – Batch vs. streaming inference, A/B rollout strategies, and monitoring for model drift.

Example questions or scenarios:

• "Design an end-to-end architecture for a real-time dispatch system that handles 12 million events annually."
• "How would you orchestrate a pipeline that retrains a model weekly and promotes it to production automatically?"
• "What telemetry would you instrument to monitor the health of a dispatch optimization service?"

As a Machine Learning Engineer at Agero, your day-to-day work is centered on the Swoop dispatch management platform. You are responsible for architecting and shipping Python services that ingest model outputs and run constrained optimization logic to surface real-time decisions. This is a hands-on coding role where you will design batch and streaming pipelines to ensure data flows reliably from the source to the model and back to the product.

You will also spend significant time modeling and simulating. This involves building and extending ML models using frameworks like XGBoost or PyTorch and running time-horizon simulations to quantify the trade-offs between cost and service levels. You aren't just predicting outcomes; you are simulating the entire marketplace dynamics to understand how a change in the dispatch algorithm affects the ecosystem.

Operational excellence is a major part of the role. You will automate training, validation, and A/B rollouts using tools like SageMaker and Airflow. Beyond the code, you will lead and collaborate, partnering with Product and Operations teams to present findings to executives and mentoring a squad of data scientists and engineers. You will continuously improve the system by instrumenting NPS and cost telemetry to identify failure modes and iterate on solutions.
