Senior Applied AI Engineer

About us:

Axiomatic AI is building a new class of AI systems designed to reason with the rigor of the scientific method. By combining deep learning with formal logic and physics-based modeling, we create verifiable, interpretable AI systems that collaborate with and support human researchers in high-stakes scientific and engineering workflows.

Our mission, 30×30, is to deliver a 30× improvement in the speed, accessibility, and cost of semiconductor and photonic hardware development by 2030.

We aim to revolutionize hardware design and simulation in these industries and are building a team of highly motivated professionals to bring these innovations from research into commercial products.

Position Overview

As a Senior Applied AI Engineer, you are the bridge between AI research and production software. You will:

Partner with users and internal stakeholders to identify high-impact workflows where AI can help

Design and implement LLM-powered product features (agents, tools, prompting strategies) using frameworks like PydanticAI (or similar)

Make principled trade-offs between models and approaches (quality, latency, cost, privacy, reliability)

Enable AI developers to deploy their work reproducibly and safely

Establish engineering standards for applied AI development: testing, reviews, maintainability, and operational readiness

Collaborate with backend engineers to integrate AI capabilities into the product

Mentor junior AI developers and supervise PRs to ensure high quality and consistent patterns

Monitor, evaluate and optimize AI and agentic workflows

Collaborate with specialist and scientist in bringing their expertise into the AI product

Your mission

Applied AI Product Development

Own applied AI features end-to-end: discovery → design → implementation → rollout → iteration

Translate user feedback and behaviour into clear technical requirements and pragmatic delivery plans

Build LLM workflows such as tool-calling agents, structured output pipelines, retrieval/tool integrations, and safe prompting strategies

Iterate quickly while keeping production quality (readability, maintainability, debuggability)

Model & Prompt Strategy

Select and evaluate LLMs (OpenAI/Anthropic/others) based on real constraints: quality, cost, latency, context limits, and reliability

Develop prompt patterns and guardrails (structured prompts, schemas, constraints, fallbacks)

Design and run lightweight evaluations to prevent regressions (golden datasets, acceptance criteria, failure-mode testing)

Document model decisions and trade-offs in a way that enables other engineers to execute confidently

Production Engineering & Quality

Write production-grade code: clear abstractions, solid API boundaries, strong typing where appropriate, and consistent error handling

Define and enforce testing practices for applied AI (unit tests, integration tests, golden/regression tests)

Implement instrumentation appropriate for debugging and iteration (basic logging/tracing/metrics for AI features)

Ensure reliability and security basics: rate limiting where needed, safe input handling, prompt-injection awareness, and sensible defaults

Experience in shipping data projects to real users

Collaboration & Enablement

Experience collaborating with software engineers

Work with AI Developers to productionize their experiments regarding improving user workflows

Define workflows: notebook/test repository → PR → staging → production

Document AI infrastructure and best practices

Review code and mentor AI developers on software practices

Communication skills: able to precisely and concisely justify decisions and explain technical concepts to colleagues and stakeholders.

Key requirements

7+ years of software engineering experience (Python preferred) with strong production ownership

Experience with LLMs and AI/ML in production: OpenAI API, HuggingFace, LangChain, or similar (beyond prototypes)

Strong software engineering fundamentals: design patterns, code structure, testing practices, and code review habits

Cloud infrastructure experience: GCP (Vertex AI preferred) or AWS (SageMaker)

API/service development experience (e.g., FastAPI/REST/async programming)

CI/CD and DevOps: Docker, Terraform, GitHub Actions

Monitoring and observability

Problem-solving mindset

Operating experience with AI deployment in enterprise environment

Proactiveness and versatility: The role requires being comfortable with defining and scoping tasks independently as well taking the initiative and finding ways to improve

Nice-to-Have

Experience fine-tuning or training models

Familiarity with LangChain, Pydantic AI or similar frameworks

Knowledge of prompt engineering and evaluation techniques

Experience with real-time inference and streaming responses

Background in data engineering or ML engineering

Understanding of RAG architectures

Contributions to open-source AI/ML projects
