Software engineer, agents

About the role

We’re seeking a highly skilled fullstack software engineer to join our engineering team building advanced AI‑driven agent systems that execute autonomous workflows, orchestrate multi‑step tasks, and extend human capacity across enterprise applications. In this role, you’ll play a key part in designing, building, and scaling next‑generation AI agents that integrate with enterprise data and services to solve real‑world problems. You will collaborate with cross‑functional teams to turn complex agent concepts into production‑ready systems.

• Design, implement, and maintain scalable, secure agent‑driven services and systems that autonomously accomplish tasks using modern AI frameworks.

• Develop and enhance robust infrastructure and high‑throughput APIs, focusing on core agent capabilities such as memory, communication channels, skills, intelligent decision logic, security and workflow management.

• Integrate agent capabilities with backend services, data stores, vector databases, search/retrieval systems, and external APIs.

• Collaborate with product managers, AI researchers, data engineers, and UX teams to translate high‑level agent use cases into robust, production‑ready software.

• Ensure reliability, monitoring, and observability for all agent components (metrics, logging, CI/CD, fault tolerance).

• Contribute to architectural design decisions and participate in rigorous code reviews to uphold quality and maintainability.

• 3+ years of professional software engineering experience with strong proficiency in Python in production environments.

• Proficiency in native agentic coding, demonstrated through the daily use of tools like Cursor, Claude Code, and other agentic coding platforms.

• Demonstrated experience building distributed systems, microservices, or complex backend APIs that support AI/agent workflows.

• Solid expertise with systems that integrate AI models, agent frameworks (e.g., Lang Chain or platform‑specific tooling), vector databases, and large context reasoning services.

• Understanding of agent orchestration patterns, state management, and asynchronous workflows.

• Experience with cloud platforms (e.g., AWS, GCP, Azure), containerization (Docker, Kubernetes), and operational engineering best practices.

• Good grasp of performance optimization, testing frameworks, and CI/CD pipelines.

• Excellent communication and collaboration skills, with a “connect + challenge + own” mindset.

• Past work on AI agents that coordinate multi‑step actions, reasoning, or autonomous decision‑making loops.

• Contributions to open‑source agent toolkits or SDKs.

• Experience with frontend technologies (React, Type Script) for tooling around agent management interfaces.

• Generous PTO, plus company holidays.

• Medical, dental, and vision coverage for you and your family.

• Paid parental leave for all parents (16 weeks).

• Fertility and family planning support.

• Early‑detection cancer testing through Galleri.

• Flexible spending account and dependent FSA options.

• Health savings account for eligible plans with company contribution.

• Annual work‑life stipends for:

  • Wellness stipend for gym, massage/chiropractor, personal training, etc.

  • Learning and development stipend.

• Company‑wide off‑sites and team off‑sites.

• Competitive compensation, company stock options and 401k.
