Overview

Join to apply for the AI Agent Engineer role at Symbolica AI.

About Symbolica: Symbolica is an AI research lab pioneering the application of category theory to enable logical reasoning in machines. We are a well-resourced, nimble team of experts focused on bridging theoretical mathematics and cutting-edge technologies to build symbolic reasoning models that think like humans—precise, logical, and interpretable. We pursue a fast-paced, results-driven approach that combines rigorous research with product-focused machine learning in a tight feedback loop.

Founded in 2022, we have raised over $30M from leading investors to push the boundaries of applying formal mathematics and logic to machine learning. Our vision is to create AI systems that transform industries and solve humanity's most complex challenges with precision and insight. Join us to redefine the future of AI by turning groundbreaking ideas into reality.

Role

We're looking for an AI Agent Engineer—a software engineer with deep experience in ML, LLMs, and/or agentic systems—to push the limits of our internal agent framework and shape its design. You'll work side-by-side with researchers, ML engineers, and leadership to turn ambitious ideas into real-world systems. Expect to move fast, handle ambiguity, and fill the critical execution gap between research and production. This is an onsite role based in our SF office (345 California St).

Your Focus

• Design new agentic systems in our framework that were previously infeasible elsewhere — and test their limits.
• Implement and evaluate open-source agentic systems (and customer-specific ones) within our framework.
• Identify and solve bottlenecks in today's agent ecosystem (e.g., context engineering, MCP constraints, inter-agent communication, memory).
• Stay ahead of the curve by tracking new research and incorporating cutting-edge AI features as they're released.

About You

• Deep understanding of LLM architecture and inference-time optimisation.
• Strong knowledge of the agentic ecosystem (frameworks, tools, MCP servers, MAS architectures).
• Track record of rapid prototyping in the LLM/agent space.
• Experience orchestrating and evaluating complex multi-agent systems.
• Solid software engineering skills in Python and/or TypeScript.

Nice-to-haves

• Experience with autonomous, dynamic multi-agent systems (beyond DAGs).
• Context engineering expertise.
• Embedding models & RAG.
• Improving model performance via fine-tuning.

What We Offer

• Competitive salary + early-stage equity package.
• High-trust, execution-first culture with minimal bureaucracy.
• Direct ownership of meaningful projects with tangible impact.
• A rare chance to work at the interface of deep research and real-world productization.

Candidates for this position must be legally authorized to work in the United States. This position is not eligible for visa sponsorship or support.
