About the role

Key responsibilities & impact

Partner in shaping the technical approach and architecture of agentic systems, helping translate evolving needs into practical, scalable solutions.
Design and implement agentic workflows that support two-way interaction between humans, agents, and internal systems.
Build and orchestrate workflow logic using tools and frameworks such as Zapier + code, n8n (or similar), APIs, and event-driven architectures.
Partner to integrate people-focused agentic workflows into a cohesive, reliable entry-point experience.
Bring a technical perspective to early-stage ideas and prototypes, helping assess feasibility, trade-offs, and paths to production.
Help evolve early implementations into more robust, maintainable, and production-ready systems.
Help establish and document patterns for reliability, observability, and safe failure in agentic workflows.
Ensure implementations align with defined trust models, escalation rules, and human-in-the-loop principles.
Work hands-on with LLMs, prompts, and agent behaviour to prioritize correctness, clarity, and human accountability.
Evaluate and integrate tools, frameworks, and platforms that support agentic patterns as the system matures.
Contribute to and document shared standards and patterns for AI-augmented systems at Orium.
Design and evolve retrieval and indexing approaches (e.g., RAG, structured knowledge sources) to ensure agents operate on accurate, relevant, and up-to-date context.

Requirements

What you’ll need

Experience building, integrating, or supporting AI / LLM-powered systems, with an emphasis on reliability, validation, and safe failure.
Proven experience taking systems from prototype to production, including defining architecture, managing trade-offs, and ensuring reliability at scale.
Strong experience building backend systems, workflows, or integrations, including APIs, event-driven systems, and automation frameworks.
Comfortable working with orchestration tools and workflow engines (e.g., Zapier + code, n8n, Temporal, Airflow, or similar), including extending platforms with custom logic where needed.
Experience designing or contributing to system architecture, particularly in integration-heavy or distributed systems.
Strong proficiency in JavaScript/Typescript, including building and deploying backend services, integrations, or extensions to support workflow and automation systems.
Comfortable taking ownership in ambiguous problem spaces, helping define the path forward rather than waiting for fully defined requirements.
Strong collaborator who enjoys building in partnership with product, domain, and systems owners.
