At Orbital Witness, we leverage the latest advancements in large language models (LLMs), including OpenAI’s GPT-4o, o1, and Claude models from Anthropic. This is an exciting opportunity for someone who is passionate about LLMs, AI agents, and agentic architecture, and who wants to work at the forefront of AI technology in production use cases.

We are open to candidates from diverse backgrounds—whether in software engineering, ML engineering, or data science—who have transitioned into AI Engineering. While commercial experience in a company is a preference, it is not mandatory. What matters most is your demonstrated interest in the domain and hands-on experience using LLMs to solve technically complex problems.

You’ll own the end-to-end design and development of AI-driven features and systems, working alongside a dynamic and fast-paced team focused on quality, usability, and impact. You will play a critical role in every stage of the development lifecycle, from discovery and design to implementation, deployment, and continuous improvement. Supported by a cross-functional team, you will deliver impactful solutions initially to lawyers and then to a broader B2B customer base.

You’ll get a chance to:  ‍ ‍

• Take ownership of key AI technology decisions and lay the groundwork for the company’s ambitious growth plans.
• Design, develop, and deploy AI-driven systems and features, integrating state-of-the-art LLMs.
• Collaborate with a cross-functional team (AI Engineers, AI product managers, VP of AI, legal domain experts and software engineers) to define user stories, rapidly experiment, and ship new features.
• Explore and implement advanced concepts such as multi-agent systems, retrieval-augmented generation (RAG), and agentic architectures.
• Champion quality and reuse across the product and the codebase.
• Work across the business to ensure the features you develop have a real impact on customers and move key business metrics as we design and build a brand-new product that doesn’t yet exist in the market.
• Participate in architecture and code reviews to continuously improve the quality, maintainability, security, and scalability of our applications.

• You have experience with backend Python development.
• You value shipping early and often to get customer feedback and then iterating quickly to improve the product.
• You have excellent verbal and written communication skills in English.

It would also be nice if you have:

• Hands-on experience with OpenAI’s GPT-4o, o1, and Claude models from Anthropic.
• Familiarity with vector databases (e.g., Pinecone, Weaviate, or similar).
• Experience building applications with Docker and Kubernetes.
• Proven expertise in building highly secure, fault-tolerant APIs.
• Experience building high-performance, distributed systems at scale.
• A strong understanding of modern dev practices like 12 Factor, CI/CD, and observability tools such as Datadog or Prometheus.
