Complex business workflows often span multiple systems, decisions, and manual handoffs that are difficult to automate with traditional tools alone. Hiring an agentic AI developer gives you specialized expertise to build AI systems that can coordinate multistep work while incorporating the controls, monitoring, and human oversight your business requires.
What does an agentic AI developer do?
An agentic AI developer designs and builds AI systems that can plan and execute multi-step tasks across applications, data sources, and business processes. These systems may use AI models to make decisions, call tools and APIs, update records, evaluate results, and escalate work for human review when needed.
Agentic AI developers typically:
- Design agent architectures, workflows, and approval checkpoints
- Connect AI agents with APIs, databases, business applications, and other tools
- Configure permissions, guardrails, validation rules, and human-in-the-loop controls
- Build memory or state-management systems to maintain context across multi-step workflows
- Develop evaluations and tests to measure reliability, accuracy, and task completion
- Implement monitoring, logging, error handling, and fallback processes for production systems
- Document workflows, integrations, escalation paths, and operational requirements
Agentic AI developers may collaborate with automation engineers on workflow orchestration and AI engineers on model selection, evaluation, infrastructure, and deployment.
How to hire an agentic AI developer on Upwork
Hiring an agentic AI developer on Upwork follows four clear steps, from posting your job to defining the scope and starting work. On Upwork, 89% of first-time clients complete a contract. For an agentic AI project, itโs especially important to define what the system can do, which actions require human review, and how youโll measure success.
Step 1: Post a job
Start with a clear job post to help agentic AI developers understand the workflow, systems, and level of autonomy your project requires.
- Describe the workflow you want to automate, such as support triage, CRM enrichment, research, or sales operations
- Identify the applications, tools, databases, and APIs the system must interact with
- Define the data the system can access or update, along with security and permission requirements
- Specify which actions can happen autonomously and which require human approval
- Share expected outputs, evaluation criteria, timeline, budget, and any reliability or compliance requirements
- Review this AI developer job description template and adapt it to your agentic AI project
Use the Job Post Generator powered by Umaโข, Upwork's Mindful AI, to draft a job post in minutes. Describe your workflow and key integrations in a few sentences and Uma will create a draft you can refine. On Upwork, the average time from job post to first proposal is just three hours.
Step 2: Evaluate candidates
Focus on candidates who can demonstrate experience building multistep AI workflows rather than general familiarity with AI tools.
- Examine portfolio examples for tool calling, workflow orchestration, API integrations, human handoffs, or deployed agentic systems
- Assess how candidates approach guardrails, permissions, evaluations, monitoring, and failure scenarios
- Look for experience with the models, frameworks, APIs, cloud services, and business systems your project requires
- Read case studies for evidence of reliability, measurable outcomes, and thoughtful handling of edge cases
- Consider client feedback, work history, Job Success Score, and talent badges alongside technical experience
Uma can conduct instant video interviews and provide shortlists of candidates with side-by-side comparisons, helping you narrow your choices before scheduling deeper conversations.
Step 3: Interview your top choices
Use interviews to understand how candidates make decisions about autonomy, reliability, and human oversight.
- Walk through your workflow and ask how they would break it into agent actions, tool calls, and approval points
- Ask how they determine when the system should act autonomously, retry a task, or escalate to a person
- Discuss how they test agent workflows, evaluate outputs, and handle unexpected or invalid results
- Explore how they limit permissions and protect sensitive data when connecting agents to business systems
- Ask how they monitor reliability, costs, failures, and performance after deployment
- Consider a small paid test project, such as designing or implementing one contained workflow with defined tools and approval points
- Adapt these AI developer interview questions to evaluate the technical skills your project requires
Schedule and conduct interviews within Upwork Messages, and Uma provides an instant transcript and summary after each call.ย
Step 4: Agree on scope and begin work
Before work begins, align on system boundaries, deliverables, access, milestones, and success criteria.
- Define deliverables such as agent workflows, integrations, evaluation suites, monitoring dashboards, documentation, and production deployment
- Set milestones for architecture, prototype development, integration, evaluation, security testing, and deployment
- Specify which systems and data the agent can access, what permissions it receives, and which actions require human approval
- Provide access to development environments, APIs, test data, documentation, and business systems as needed
- Agree on evaluation criteria, failure thresholds, escalation paths, monitoring responsibilities, and acceptance criteria
- Clarify ownership of source code, prompts, workflow configurations, documentation, and other project assets
Manage everything through messaging and the contract workroom, with identity verification, payment protection, hourly tracking, and project funds keeping work secure. Uma helps you track milestones and next steps.ย
