Sanity developers help businesses turn content strategy into structured, reusable content systems for websites, apps, product catalogs, editorial workflows, and multi-channel publishing. Hiring a skilled Sanity developer can help your team model content clearly, support editors with a tailored Studio experience, and connect content to modern front-end frameworks while keeping content structured for modern, multi-channel delivery.
What does a Sanity developer do?
A Sanity developer builds, customizes, and maintains Sanity-based content management systems so teams can create, manage, query, and publish structured content. Their work typically includes designing content schemas, customizing Sanity Studio for editorial workflows, connecting Sanity’s Content Lake to a website or application, writing GROQ or GraphQL queries, setting up APIs and webhooks, managing migrations, and configuring roles and permissions for team access where the Sanity plan allows.
Common deliverables include schema design files, customized Sanity Studio configuration, API integration code, migration scripts with validation reports, and setup documentation. Depending on project scope, a Sanity developer may collaborate with front-end developers building the user interface, content strategists defining content models, or marketing teams managing publishing workflows.
How to hire a Sanity developer on Upwork
Hiring a Sanity developer on Upwork means defining your content requirements, posting a role-specific job, evaluating candidates against similar CMS work, interviewing for technical judgment, and agreeing on scope before work begins. A clear hiring process helps candidates understand the system you need and helps you compare proposals based on deliverables rather than vague CMS experience.
Step 1: Post a job
Start by describing what you need built, improved, or migrated. A strong Sanity developer job post includes:
- Project scope and deliverables, such as new setup, schema design, migration, or front-end integration
- Current tech stack and target front-end framework, such as React, Next.js, Vue, or Gatsby
- Content model requirements, including product catalogs, blogs, localization, or references between content types
- Migration needs, including the source CMS, content volume, transformation rules, and validation expectations
- Success criteria, such as tested queries, approved content types, working previews, or completed editor training
- Timeline, review process, and budget structure for hourly or fixed-price milestones
You can use the Job Post Generator, powered by Uma™, Upwork’s Mindful AI, to create a customizable draft. Describe your project in a few sentences, then refine the draft with your content types, integrations, timeline, and deliverables. You can also review job description templates to structure your post around responsibilities, required skills, and success criteria.
Step 2: Evaluate candidates
Review profiles and proposals for Sanity experience that matches your project type. Focus on:
- Portfolio examples showing Sanity projects, headless CMS builds, or similar content architecture work
- Code samples or GitHub repositories demonstrating schema design, GROQ queries, GraphQL use, or API integrations
- Proposal quality, including how the candidate handles content modeling, migration risk, validation, and handoff
- Front-end framework fit, especially if your project uses Next.js, React, Vue, or Gatsby
- Client reviews that mention documentation, communication, collaboration with non-technical teams, or reliable delivery
- Risk checks, including availability, time zone overlap for reviews, quality assurance process, and access requirements after contract start
Upwork’s shortlist and comparison features can help you organize candidates side by side before scheduling interviews. You can also look for talent badges such as Top Rated or Expert-Vetted when you want additional signals from work history and client feedback.
Step 3: Interview your top choices
Interview your top candidates with a structured 20-30 minute agenda that validates Sanity expertise, communication style, and practical judgment. Use the conversation to test how they think through content models, not just whether they have used Sanity before.
Ask questions such as:
- How would you structure schemas for our content types, references, and reusable modules?
- How do you decide when to use GROQ versus GraphQL for a Sanity project?
- What steps would you take to reduce migration risk and validate imported content?
- How would you set up previews, webhooks, or publishing workflows for editors?
- How do you document schemas, queries, and editorial workflows for handoff?
- How do you estimate timelines when stakeholders are still finalizing content requirements?
You can use Instant Interviews to collect structured video responses before live discussions. Upwork’s built-in messaging, audio, and video tools can also help keep interview communication in one place.
Step 4: Agree on scope and begin work
Before work starts, finalize the contract so deliverables, review points, communication expectations, and payment terms are clear. A well-scoped Sanity contract should define what the freelancer will build, what you will provide, and how changes will be reviewed.
Before the project starts:
- List final deliverables, such as schema files, Studio configuration, integration code, migration scripts, and documentation
- Set milestones for fixed-price work or weekly hour expectations for hourly work
- Define success criteria, such as content types validated, queries tested, previews working, and editor training complete
- Confirm communication cadence, including updates, review meetings, and stakeholder feedback windows
- Document the revision process and how scope changes will be approved
- For fixed-price work, fund milestones before work begins so each deliverable has a clear review and approval point
