We are growing our team and looking for a Lead ML/AI Platform Engineer.

Job Description

Overview

As a Lead ML/AI Platform Engineer at SavvyMoney, you will own the platform that takes machine learning from experiment to production — training infrastructure, model serving, inference pipelines, and the integration seams with our Java microservices.

You will set technical direction for AI/ML across the company alongside our Data Platform Architect, and drive the engineering side of our GenAI/LLM and agent strategy — from retrieval architectures and evaluation harnesses to the guardrails required to run agentic workflows responsibly in a regulated environment.

What You'll Do

• Partner with our Data Platform Architect to set technical direction for AI/ML across the company — architecture, tooling, standards, and build-vs-buy decisions.

• Own the ML/AI platform: training infrastructure, model serving, inference pipelines, and production integration.

  • Feature engineering, model training, model registry, and hosted inference in Amazon SageMaker

  • GenAI/LLM usage, fine-tuning, and agentic workflows in Amazon Bedrock and AgentCore

  • Feedback and data pipelines built on AWS Glue, Lambda, and Step Functions

• Own the serving layer and integrate ML services cleanly with our Java microservices — define the API contracts and make the latency and throughput trade-offs.

• Drive the engineering side of our GenAI/LLM strategy: retrieval architectures, evaluation harnesses, serving patterns, and the judgment calls about which approach fits which problem.

• Bring depth on the emerging agent stack — MCP, agent workflow patterns, stateless and stateful designs, and the guardrails needed to run them responsibly in a regulated environment.

• Partner with our Data Scientist on the handoff from experimentation to production: productionize models, stand up the feature pipelines and serving infrastructure they need, and shorten the loop between training and deployment.

• Work with product, data, and engineering leadership to identify the highest-impact ML opportunities and translate them into roadmaps.

• Represent the AI/ML function in cross-functional forums, communicating trade-offs clearly to technical and non-technical audiences alike.

What We're Looking For

Required

• 8+ years in software or ML engineering, including 5+ years shipping production ML systems and a track record of owning ambiguous, high-scope problems end to end.

• Demonstrated technical leadership: you've shaped the ML strategy of a team or organization, mentored senior engineers, and been the person others rely on for difficult architectural calls.

• Hands-on experience with both operating models we use:

  • AWS managed ML stack: Amazon SageMaker (training, tuning, hosted endpoints, model registry), Amazon Bedrock, and AgentCore for GenAI and agentic workflows.

  • Open-source ML tooling: JupyterLab for notebooks, Spark for distributed processing, MLflow for experiment tracking and model registry.

• Deep working knowledge of the AWS stack — S3, Athena, Redshift, Glue, Step Functions, Lambda — plus SQL skills strong enough to model data for both analytical and ML workloads.

• Production experience with GenAI/LLMs: RAG, prompt engineering, evaluation, and a clear grasp of the cost, latency, and safety trade-offs involved.

• Familiarity with vector databases (e.g., pgvector, Pinecone) and sound judgment on when they're warranted versus alternatives such as NoSQL retrieval.

• Working knowledge of Java sufficient to review service code, define API contracts, and debug integration issues with our microservices.

• Deep expertise in Python and the core ML stack: scikit-learn, pandas, NumPy, PyTorch and/or TensorFlow, XGBoost / LightGBM.

• Solid MLOps fundamentals — model monitoring, drift detection, reproducibility, experiment tracking, model registry, and cost observability — plus the ability to partner with DevOps on CI/CD rather than build it from scratch.

• Excellent written and verbal communication — you can write both the design doc that aligns a dozen engineers and the one-pager that aligns the exec team.

• Strong collaborator, comfortable operating in a role where scope is shared: you'll partner with a Data Scientist on models and DevOps on infrastructure, and you can navigate those seams while keeping clear ownership.

• Ability to operate as an independent contractor through your own entity or an approved contracting arrangement, with reliable overlap with US Pacific business hours for architecture reviews and cross-team work.

Nice to Have

• Experience with ClickHouse or a comparable columnar / real-time analytical database.

• Fine-tuning experience (LoRA / QLoRA, instruction tuning, or RLHF).

• Streaming and real-time inference experience (Kafka, Kinesis, low-latency serving).

• Infrastructure-as-code (Terraform, AWS CDK, CloudFormation).

• Experience operating ML systems at meaningful scale — hundreds of millions of predictions per day, or equivalent.

• Open-source contributions, conference talks, papers, or patents in ML / applied ML.

Who You'll Work With

• Data Scientist — leads feature engineering, model training, fine-tuning, and experimentation. You'll partner on the research-to-production handoff, stand up the infrastructure they need, and jointly own the quality of what ships.

• DevOps — owns CI/CD, deployment infrastructure, and platform observability. You'll partner on ML-specific extensions (model artifacts, reproducible environments, canary and shadow deployments) rather than rebuilding what already exists.

• Backend engineers — own the Java microservices that consume ML outputs. You'll define the contracts and own the serving side.

• Product and engineering leadership — you're the technical voice on what we should build with AI/ML, and how.

Our Stack

• Distributed processing: AWS Glue

• Orchestration: AWS Lambda, AWS Step Functions

• Managed ML: Amazon SageMaker, Amazon Bedrock, AgentCore

• Open-source ML: JupyterLab, Spark, MLflow

• Storage & query: Amazon S3 (data lake), Amazon Athena, Amazon Redshift, ClickHouse

• Languages: Python (ML, pipelines), Java (microservices)
