SentiLink is hiring a Founding Senior Machine Learning Engineer

About the Role

As a founding Senior Machine Learning Engineer, you’ll play a central role in building the backbone of real-time machine learning systems that power identity verification and fraud detection. This is a high-impact position requiring deep technical ownership—from designing monitoring frameworks to enabling reproducible experimentation and ensuring models operate reliably in production.

What You'll Do

  • Lead the development and evolution of real-time model monitoring systems, ensuring visibility into model behavior and performance across live environments.
  • Design and maintain infrastructure for ML experimentation, model tracking, and version control to support full lifecycle transparency and reproducibility.
  • Streamline the model development workflow by addressing tooling gaps, improving code quality, and accelerating iteration speed for data science teams.
  • Act as the technical liaison between Data Science and Engineering, defining standards for integration, deployment, and operational handoffs.
  • Optimize production model performance with a focus on latency, reliability, and maintainability under real-world conditions.
  • Respond to performance anomalies and partner escalations with root cause analysis and targeted improvements.
  • Research, prototype, and integrate new tools and platforms that enhance ML capabilities, working closely with data scientists to validate impact.

Requirements

  • 5+ years of experience in software engineering or machine learning infrastructure roles, with a degree in Computer Science, Engineering, Mathematics, or a related field.
  • Strong programming skills in Python and SQL, with fluency in Git and modern CI/CD practices.
  • Hands-on experience with MLflow or similar model tracking platforms, and familiarity with observability tools such as Datadog, Prometheus, or Grafana.
  • Proven track record building and maintaining ML pipelines for training, evaluation, and deployment.
  • Experience deploying ML models as scalable services, with attention to performance and operational rigor.
  • Proficiency with containerization (Docker), orchestration (Kubernetes), and workflow tools like Airflow, Dagster, or Prefect.
  • Knowledge of model serving frameworks and deployment patterns in cloud environments, particularly AWS.
  • Ability to rapidly prototype and deliver end-to-end ML solutions from concept to production.
  • Adaptability in fast-changing technical environments with evolving requirements.
  • Must be legally authorized to work in the United States and reside within the country.

Work Mode

This role supports a hybrid model across select U.S. and India locations, including Austin, San Francisco, New York City, Seattle, Los Angeles, Chicago, Gurugram (Delhi), and Bengaluru. The company operates digitally-first with strong cross-regional collaboration. While remote options exist, those near office hubs are encouraged to engage in person regularly. Some teams, including engineering in India, primarily work from the Gurugram office.
