Software engineers and AI agents alike suffer from the same problem: finding that one person or place that will answer their tough, specific question. Many solutions promise to solve this with similarity search in vector databases. Unfortunately, finding the answer is often a puzzle with pieces to be collected across a myriad of contradictory sources and cannot be solved without surgical search and careful reasoning.

Spectrum collects data from an organization's code, docs, and issues, and organizes knowledge in a unified ontology that AI agents can efficiently search through and reason over. We aim to revolutionize the semantic layer space for software-building organizations and move beyond specs that fall out of sync with code, introducing a living spec – one that's extracted from the whole system and used to keep it aligned. Spectrum is meant to be the single source of truth for all product and architectural knowledge.

A resident of JetBrains' startup incubator, Spectrum enjoys startup speed and autonomy, and is backed by 25 years of developer tooling expertise.

• Prototyping and validating research ideas, then collaborating with ML and software engineers to bring them to production.
• Collaborating with JetBrains Research and external academic advisors to shape our research agenda.
• Publishing research findings at top venues and representing Spectrum in the research community.

We expect you to have:

• A PhD (or equivalent research experience) in NLP, knowledge graphs, ontology learning, information extraction, or a closely related field.
• A strong publication record in at least one of the following areas: knowledge graph construction, ontology learning, information extraction, or NLP.
• Experience applying LLMs to structured knowledge extraction tasks.
• Experience designing and running rigorous experiments, including hypothesis formulation, ablation studies, and statistical evaluation.
• Strong Python and PyTorch skills, with the ability to implement research ideas from scratch.
• Excellent communication skills, with the ability to explain complex technical concepts to diverse audiences.
• Proficiency in English, both written and verbal.

Our ideal candidate would also have:

• Experience with ontology engineering, semantic web technologies (OWL, RDF, SPARQL), or ontology alignment.
• A background in code analysis, developer tools, or software engineering research.
• Experience with knowledge graph embedding methods or graph neural networks.

We are already serving 2000+ companies (e.g. Rituals, Deloitte, Decathlon, KPMG, and McDonalds), through which 600K+ employees have access to our product.

About the role

As a Senior AI Engineer at OpenUp, you will own the design, build, and evolution of our AI-powered product experiences — starting with our AI Guide, which serves 600K+ users seeking mental and physical wellbeing support.

We're moving from single-prompt to multi-agent architectures that orchestrate tools, manage memory, and hold meaningful conversations at scale. You'll focus on conversational quality, evaluation infrastructure, and user trust — knowing the difference between a demo and a production system.

• Evaluation as a first-class concern. We operate in mental health, where a bad recommendation isn't just a UX issue. You'll build pipelines that measure conversational quality, safety, and clinical appropriateness — with regression detection before every deployment.
• Model-agnostic architecture. You'll design abstraction layers that allow seamless switching between Azure OpenAI, open-source models, and future providers.
• Prompt engineering at scale. You'll design, version, test, and optimise prompts across multiple agent personas — and build tooling that makes iteration fast, measurable, and safe.

You'll collaborate closely with Product, Design, Backend Engineers, and Security to translate product intent into scalable, trustworthy AI systems.

Responsibilities

• Multi-agent architecture and orchestration: Design and build agent-based systems that go beyond rigid scripts. Implement orchestration patterns including tool usage, inter-agent communication, memory management, and context handling. Own architectural decisions about when to use single-agent vs. multi-agent approaches and how agents hand off to each other.
• Evaluation and quality infrastructure: Build and maintain evaluation pipelines that catch regressions before users do. Design golden datasets, automated evaluation rubrics, and monitoring dashboards. Establish quality gates that every prompt change and model update must pass. This is the most critical part of the role in a mental health context.
• Prompt engineering and optimization at scale: Design, version, and optimize prompts across multiple agent personas and conversation types. Build the tooling and processes that make prompt iteration systematic: A/B testing frameworks, performance benchmarks, cost analysis, and safety checks. Treat prompt engineering as a proper engineering discipline with version control, testing, and rollback.
• RAG and grounding systems: Build AI systems grounded in OpenUp content using techniques such as RAG and agentic retrieval. Ensure the AI Guide draws from verified clinical content, articles, and expert knowledge rather than generating unsupported claims. Optimize retrieval quality, relevance, and latency.
• Production AI systems: Productionize AI solutions on Azure, including monitoring, observability, and continuous improvement. Own the operational health of AI features: latency, cost, error rates, and user satisfaction metrics. Work with the platform team on deployment, scaling, and reliability.
• Model-agnostic design for data sovereignty: Contribute to architecture decisions that keep the application layer decoupled from any single model provider. Design configuration-driven model selection and data isolation patterns that enable future private cloud and on-premise deployment scenarios for enterprise customers.
• Cross-functional collaboration: Collaborate with Product and Design to align AI behavior with intended user experience. Work with clinical advisors on safety and appropriateness. Balance user experience with privacy, safety, and compliance requirements (GDPR, EU AI Act).

About you

You are curious about how technology is rapidly evolving and our place in it, and motivated by building solutions that have a real impact on people's lives. You believe that learning comes from action, iteration and feedback, and that strong user value and trust go hand in hand.

• 5+ years software engineering experience, with at least 2+ years building and shipping AI or LLM-based systems in production
• Strong background in data science or machine learning. You understand statistical evaluation, experimental design, and can reason about model performance beyond accuracy scores
• Fluent in Python. Experience with .NET is a plus (our backend stack includes .NET, SQL Server, and ReactJS)
• Hands-on experience with multi-agent or agent-based architectures: orchestration, tool calling, memory, state management
• Experience designing and operating evaluation pipelines for LLMs or conversational systems. You have opinions on how to measure conversational quality and can build the infrastructure to do it
• Experience with prompt engineering at production scale: versioning, A/B testing, regression detection, cost optimization
• Working knowledge of Azure OpenAI or similar LLM platforms (OpenAI, Anthropic, Google)
• Familiarity with embeddings, vector search, RAG, and grounding techniques
• Ability to reason about AI risks: hallucinations, failure modes, adversarial inputs, and trust concerns in sensitive domains
• Bachelor's or Master's degree in computer science, data science, machine learning, or equivalent experience
• Fluent in English

Nice to have

• Experience with open-source LLMs (Llama, Mistral, or similar) and self-hosted model deployment
• Experience working in regulated or trust-sensitive domains (healthcare, mental health, fintech)
• Background in NLP, conversational AI, or dialogue systems
• Experience with Azure AI Agent Service, Semantic Kernel, or similar orchestration frameworks
• Familiarity with fine-tuning techniques and model adaptation
• Knowledge of EU AI Act compliance requirements
