You\'ll work in a small, high-impact team that values experimentation, rapid iteration, and quality engineering. This is a chance to shape how agentic applications are built, deployed, and adopted in real-world environments.

• Architect, build, and maintain applications that integrate autonomous agents and LLMs into end-to-end workflows.
• Design APIs, services, and event-driven components that allow agents to interact with systems, data, and users effectively.
• Ensure applications are resilient, secure, and adaptable in production environments.

• Pilot and integrate agent frameworks, orchestration layers, and multi-agent systems.
• Automate repetitive tasks including code generation, testing, monitoring, and documentation.
• Continuously evaluate and incorporate emerging AI tooling.

• Define and codify best practices for designing, deploying, and monitoring agentic workflows.
• Coach peers on prompt engineering, guardrails, and safe deployment of autonomous agents.
• Establish patterns for observability, safety, and human-in-the-loop validation.

• Set high standards for design, code quality, and testing.
• Conduct architecture reviews and mentor other developers in building AI-powered systems.
• Stay current with research and industry trends in autonomous agents and applied LLMs.

• Deliver high-quality applications with strong reliability, security, and performance.
• Optimize for scalability and cost efficiency in cloud-native environments.
• Own the lifecycle from prototyping to production deployment.

• Strong background in designing APIs, distributed systems, and event-driven architectures.
• Proficiency in at least one statically typed language (Go, Java, C#) and one scripting language (Python, TypeScript, Bash).
• Hands-on experience with cloud platforms (AWS, GCP, or Azure) and container orchestration (Kubernetes).
• Demonstrated use of AI/LLM tooling in professional or side projects.
• Curiosity and creativity in exploring agentic workflows and autonomous development approaches.
• Strong communication skills and ability to collaborate across remote-first teams.

• Experience with multi-agent frameworks, orchestration tools, or AI-powered application platforms.
• Knowledge of service-mesh, observability tooling, and policy-as-code.
• Familiarity with event-driven systems (Kafka, NATS) and domain-driven design.
• Exposure to safety, ethics, and compliance considerations in AI systems.

• Remote-first with optional hub meet-ups; hardware & co-working stipend.
• Flexible core hours (overlap 9 a.m. 3 p.m. ET).
• Comprehensive health, dental, and vision coverage in Canada & the U.S.
• Generous vacation, paid learning days, and annual budget for conferences or AI tooling subscriptions.
