Associate ML Engineer

About Martinez Software:

Everything runs on a single Rails app and one Postgres database, deployed on Heroku.

About the role:

Martinez Software has an opening for an Associate ML Engineer. ML engineering role focused on pipelines, serving and monitoring. You'll work alongside data scientists rather than replace them. We're looking for an engineer to build retrieval-augmented generation features on hosted and open-weight language models, with proper evaluation. Remote position. Most of the team is in New York City, but nobody is required to come in. Most of our work is async, and meetings are kept short.

In your first few months you will:

• Fine-tune open-weight models with LoRA when it beats prompting.
• Cut inference cost with quantization, batching and caching.
• Build training pipelines in PyTorch or TensorFlow and run them on GPUs in AWS, GCP or Azure.
• Track experiments, artifacts and versions in MLflow or Weights & Biases.
• Maintain feature pipelines and a feature store such as Feast or Tecton.
• Monitor models for drift, data quality issues and latency regressions.

About you:

• 1+ years of software engineering experience, with at least two spent on ML systems in production.
• Comfortable with SQL and large-scale data processing in Spark or Ray.
• Hands-on experience with PyTorch, TensorFlow or JAX.
• Strong Python and solid engineering habits (testing, packaging, code review)
• Understanding of core ML concepts: overfitting, evaluation metrics, bias in training data.
• BS or MS in computer science, engineering or a related field.

Why work with us:

$144,000 - $167,000 per year

• Health insurance.
• 401(k) with 4% match.
• Paid sick leave.
• Gym membership reimbursement.
• Cell phone reimbursement.
• Referral program.
• Vision insurance.

Start: Immediately.
