Contract Software Engineer Remote Jobs in Milwaukee, WI

Required Qualifications

We are looking for a senior engineer who has shipped AI/ML and GenAI systems in production and can operate as a technical leader within a product scrum team.

AI/ML Engineering

• 7+ years of software engineering experience, with at least 5 years building and deploying AI/ML systems in production

• Hands-on experience with the full ML lifecycle: data preparation, model training, evaluation, deployment, monitoring, and retraining

• Strong foundation in machine learning fundamentals - supervised/unsupervised learning, time-series modeling, anomaly detection, and predictive analytics

• Proficiency in Python and relevant ML frameworks (PyTorch, TensorFlow, scikit-learn, or equivalent)

• Experience with MLOps tooling: experiment tracking, model registries, deployment pipelines, and observability

GenAI & LLM Development

• Hands-on experience building production applications across multiple LLM providers (e.g., Anthropic, OpenAI, AWS Bedrock, Azure OpenAI, and open-source models)

• Working knowledge of RAG architectures, vector databases, embedding pipelines, and retrieval strategies

• Experience with agentic frameworks, multi-agent orchestration, and tool-calling patterns - including emerging standards like Model Context Protocol (MCP) (e.g., LangGraph, CrewAI, LlamaIndex, or custom implementations)

• Strong evaluation discipline: ability to design, run, and reason about LLM evaluation pipelines - including eval datasets, LLM-as-judge techniques, and regression testing for prompts and model behavior

• Experience with LLM observability and tracing - instrumenting model calls, tool calls, and retrievals in production (e.g., LangSmith, LangFuse, or OpenTelemetry GenAI conventions)

Engineering Craft

• Strong software engineering fundamentals: clean code, system design, API development, and distributed systems

• Experience with cloud platforms (Azure preferred) and containerized deployment (Docker, Kubernetes)

• Comfortable working in an agile scrum team - shipping iteratively, participating in design reviews, and writing code others can maintain

• Ability to communicate technical concepts clearly to non-technical stakeholders and influence product decisions with data

Preferred Qualifications

• Experience in industrial, OT, IoT, or building automation environments

• Familiarity with time-series data platforms and protocols such as BACnet, MQTT, or OPC UA

• Experience with edge AI deployment and latency-constrained inference environments

• Background in energy systems, HVAC, fault detection & diagnostics, or predictive maintenance use cases

• Experience mentoring engineers or leading technical initiatives within a product team

• Familiarity with cybersecurity considerations in OT/IoT environments

• Experience implementing AI safety guardrails, content filtering, and governance controls for production GenAI systems

• Experience with LLM cost optimization - model selection, caching, token efficiency, and routing strategies

What Success Looks Like

• AI/ML and GenAI features you build are shipping in our smart building products and delivering measurable value to customers

• Developer tooling and AI-assisted workflows you introduce meaningfully reduce cycle time for the Controls SW team

• Engineers you mentor are independently applying AI/ML and GenAI patterns to new problems

• You are a trusted technical voice on the team - shaping how AI is designed, prioritized, and built across the roadmap

• The team's capacity to run AI-powered programs grows directly because of your presence

Why Johnson Controls

• Work on AI problems that have direct physical impact - buildings that use less energy, run more reliably, and operate more safely

• Join a team that is actively investing in AI as a core product capability, not a side project

• Collaborate with a multidisciplinary team of engineers, data scientists, product managers, and domain experts in building automation

• Competitive compensation, benefits, and career growth within a global engineering organization

SALARY RANGE: $85,000 - $127,000 (Salary to be determined by the education, experience, knowledge, skills, and abilities of the applicant, internal equity, and alignment with market data.) This position includes a competitive benefits package. The posted salary range reflects the target compensation for this role.
