Checkmate
We’re seeking a Mid-Level Machine Learning Engineer to join our growing Data Science & Engineering team. In this role, you will design, develop, and deploy ML models that power our cutting‑edge technologies like voice ordering, prediction algorithms, and customer‑facing analytics. You’ll collaborate closely with data engineers, backend engineers, and product managers to take models from prototyping through to production, continuously improving accuracy, scalability, and maintainability.
Essential Job Functions
Model Development: Design and build next‑generation ML models using advanced tools like PyTorch, Gemini, and Amazon SageMaker – primarily on Google Cloud or AWS platforms.
Feature Engineering: Build robust feature pipelines; extract, clean, and transform large‑scale transactional and behavioural data. Engineer features like time‑based attributes, aggregated order metrics, categorical encodings (LabelEncoder, frequency encoding).
Experimentation & Evaluation: Define metrics, run A/B tests, conduct cross‑validation, and analyse model performance to guide iterative improvements. Train and tune regression models (XGBoost, LightGBM, scikit‑learn, TensorFlow/Keras) to minimise MAE/RMSE and maximise R².
Own the entire modelling lifecycle end‑to‑end, including feature creation, model development, testing, experimentation, monitoring, explainability, and model maintenance.
Monitoring & Maintenance: Implement logging, monitoring, and alerting for model drift and data‑quality issues; schedule retraining workflows.
Collaboration & Mentorship: Collaborate closely with data science, engineering, and product teams to define, explore, and implement solutions to open‑ended problems that advance the capabilities and applications of Checkmate, mentor junior engineers on best practices in ML engineering.
Documentation & Communication: Produce clear documentation of model architecture, data schemas, and operational procedures; present findings to technical and non‑technical stakeholders.
100 % Remote
$100,000 to $140,000
Requirements
Bachelors/Master’s degree in Computer Science, Engineering, Statistics, or related field.
Experience
5+ years of industry experience (or 1+ year post‑PhD).
Building and deploying advanced machine learning models that drive business impact.
Proven experience shipping production‑grade ML models and optimisation systems, including expertise in experimentation and evaluation techniques.
Hands‑on experience building and maintaining scalable backend systems and ML inference pipelines for real‑time or batch prediction.
Programming & Tools
Proficient in Python and libraries such as pandas, NumPy, scikit‑learn; familiarity with TensorFlow or PyTorch.
Hands‑on with at least one cloud ML platform (AWS SageMaker, Google Vertex AI, or Azure ML).
Data Engineering
Hands‑on experience with SQL and NoSQL databases; comfortable working with Spark or similar distributed frameworks.
Strong foundation in statistics, probability, and ML algorithms like XGBoost/LightGBM; ability to interpret model outputs and optimise for business metrics.
Experience with categorical encoding strategies and feature selection.
Solid understanding of regression metrics (MAE, RMSE, R²) and hyper‑parameter tuning.
Cloud & DevOps Proven skills deploying ML solutions in AWS, GCP, or Azure; knowledge of Docker, Kubernetes, and CI/CD pipelines.
Collaboration Excellent communication skills; ability to translate complex technical concepts into clear, actionable insights.
Working Terms Candidates must be flexible and work during US hours at least until 6 p.m. ET in the USA, which is essential for this role and must also have their own system/work set‑up for remote work.
Preferred Qualifications
Master’s or advanced degree in Computer Science, Engineering, Statistics, or related field.
Familiarity with data‑privacy regulations (GDPR, CCPA) and best practices in secure ML.
Open‑source contributions or publications in ML/AI conferences.
Experience with Ruby on Rails programming framework.
Benefits
Health Care Plan (Medical, Dental & Vision)
Retirement Plan (401k)
Life Insurance (Basic, Voluntary & AD&D)
Flexible Paid Time Off
Family Leave (Maternity, Paternity)
Short Term & Long Term Disability
