Hire senior GraphQL developers to design and scale your API
Senior GraphQL engineers who design schemas, build federated graphs and tune resolvers inside your codebase, working within an hour of US time.
By the Ryz Labs team · Updated October 2026
Hiring GraphQL developers through Ryz gets you senior engineers who treat the schema as a product, not a thin layer over database tables. They are in the top 1% of the engineers we interview, they embed in your team and repos, and they work within an hour of US time zones.
What our GraphQL developers work on
GraphQL work spans API design, server performance and client tooling. Our engineers build servers with Apollo Server, GraphQL Yoga, Hot Chocolate, graphql-java, Strawberry or gqlgen, and on the client side they work with Apollo Client, Relay and urql. Typical projects:
- New GraphQL APIs in front of existing REST services and databases, designed around client use cases.
- Federated supergraphs with Apollo Federation or similar tools, so separate teams own separate subgraphs.
- Resolver performance work: batching with DataLoader, caching, and query cost limits.
- Real-time features with subscriptions over WebSockets or server-sent events.
- Schema governance: linting, breaking-change checks in CI, deprecation plans and a schema registry.
- Typed client setups with GraphQL Code Generator, persisted queries and normalized caches in React apps.
Skills we vet for
- Schema design. Naming, nullability choices, interfaces and unions, input types, and designing mutations that return useful payloads and errors.
- The N+1 problem. DataLoader batching and per-request caching, and recognizing when a resolver tree hides hundreds of queries.
- Pagination. Cursor-based connections in the Relay style, stable cursors, and the trade-offs against offset pagination.
- Federation. Entities, keys and reference resolvers, splitting a monolithic schema into subgraphs, and router configuration.
- Security. Field-level authorization, depth and complexity limits, persisted queries, and turning off introspection where needed.
- Caching. Client cache normalization, cache control hints, CDN caching of GET queries, and invalidation after mutations.
- Error handling. Partial results, typed errors as union results versus the errors array, and consistent error codes.
- Observability. Per-field tracing, operation names, slow-resolver detection and usage reporting to guide deprecations.
How we vet GraphQL developers
Our recruiters look for engineers who have designed and operated GraphQL APIs used by real clients, not only consumed one. ARC, our in-house system, ranks the candidate pipeline. Each candidate takes a structured NTRVSTA AI interview covering schema design, resolver performance and security. Recruiters review every candidate before and after the interview and hand you a curated shortlist. AI scores are advisory, and recruiters and hiring managers make the decisions.
Sample interview topics
- A query for 50 orders, each with its customer and line items, takes four seconds. How do you find where the time goes, and how does DataLoader change it?
- Design the schema for a checkout mutation. How do you return validation errors, payment failures and success without leaning on the top-level errors array?
- Two teams both want to own the User type in a federated graph. How do you split fields between subgraphs and resolve references?
- A public GraphQL endpoint is being hit with deeply nested queries. What protections do you add, and how do you keep them from breaking legitimate clients?
- How do you remove a field that mobile apps in the wild still query? Describe the deprecation process and how you know when it is safe.
Ways to hire GraphQL developers
| Option | Best for | Trade-offs |
|---|
| Freelance marketplace | Adding a few queries or a quick prototype | Schema design mistakes are expensive to undo. You carry the vetting and long-term ownership. |
| Staffing or recruiting agency | Broad backend hiring | Many candidates have used GraphQL from the client side only. Server and schema depth is hard to screen for. |
| In-house recruiting | A long-term API platform owner | Engineers with real federation and schema governance experience are scarce, so searches take time. |
| Ryz Labs staff augmentation | Adding senior GraphQL engineers to an existing API or product team | You direct priorities and review. Best when you know which part of the graph needs help. |
| Ryz Labs dedicated team | Building or rebuilding an API layer across several services | A team with a tech lead and backend engineers, scoped as a whole. Starts with a plan rather than single hires. |
Ryz is not the right fit if you want to pick a contractor from a marketplace and pay by the hour without a scoping conversation, or if you need people in European or Asian hours. If you want engineers employed directly on your payroll, use an employer-of-record partner.
Why hire GraphQL developers from Latin America
Product companies and agencies across Latin America have built GraphQL APIs for US clients for years, often across both the server and a React or React Native front end. That full-path experience is what GraphQL rewards: the people designing the schema understand how the client will query it.
Schema decisions involve many people, from mobile and web developers to backend owners. Working within an hour of your team, our GraphQL engineers can run schema reviews live, settle naming debates in one meeting and merge changes before the day ends. They work in English and follow your review process.

FAQ
Which GraphQL server languages do your developers use?
Most common are TypeScript with Apollo Server or Yoga, Java or Kotlin with graphql-java or DGS, C# with Hot Chocolate, Python with Strawberry and Go with gqlgen. We match on your server language.
Can they help us decide between GraphQL and REST?
Yes. A senior GraphQL engineer will tell you when REST or gRPC is simpler for a given service. Not every API benefits from a graph.
What is the price to hire GraphQL developers?
Custom quote, scoped per team. You get a plan, a price and the names of the people involved before you sign.
How do contracting and working hours work?
You sign one contract with Ryz. Our engineers work with us as independent contractors, and we handle paying them. They keep hours within an hour of US time zones.
