Hire AWS Cognito Developers Who Ship Authentication You Will Not Have to Rebuild
Hire AWS Cognito developers from Entrans and get engineers who have shipped identity for real user bases. They know how user pools differ from identity pools, how to federate with SAML and OIDC without breaking your existing logins, and how to move users in without emailing everyone a password reset. Entrans has delivered for 200+ enterprises, and interviews can start this week.
Why Market Leaders Choose Entrans AWS Cognito Developers
Authentication is the one feature every user touches and nobody forgives. Our engineers come out of our cybersecurity and compliance practice, and they have built identity platforms end to end, not just wired up a login form.
1. Identity Engineers, Not Generalists Reading Docs
Every AWS Cognito expert we put forward has run an authentication flow in production, including the parts that go wrong: token expiry during checkout, a federated provider changing its metadata, a signup trigger silently rejecting users.
2. Migrations Without Mass Password Resets
Most identity providers will not export password hashes, so a lift-and-shift is rarely possible. We migrate users just in time through the Cognito user migration trigger, so people sign in with the password they already have and never see an interruption.
3. Federation That Survives Your Enterprise Customers
SAML 2.0 and OIDC connections for corporate customers, social sign-in for consumers, and group mapping so a new enterprise tenant does not need custom code. We plan the attribute mapping before the first connection goes live.
4. Security Reviewed by People Who Do It for a Living
MFA, threat protection, refresh token rotation, and least-privilege IAM around every app client. On regulated work our security engineers review the design before it reaches production.
5. Straight Answers About Fit
Cognito is a strong fit for most AWS-native products, and it is not the right answer for every identity problem. When your needs point to fine-grained authorization or complex B2B tenant modeling, we say so early. Entrans is ISO certified and a NASSCOM member, with delivery across the US, UK, UAE, and India.
Hire AWS Cognito Developers From Entrans That Are Certified and Experienced
This is the work our AWS Cognito engineers do week to week. Bring any of it into the interview and ask for specifics.
User Pools, Identity Pools, and App Clients
Pool design that fits your tenancy model, app clients scoped per application, custom attributes planned before launch rather than bolted on, and groups mapped to the roles your product already uses.
Federation and Single Sign-On
SAML 2.0 and OIDC federation for enterprise customers, social providers for consumer apps, and hosted UI or a custom login screen depending on how much control your brand team wants.
Custom Auth Flows With Lambda Triggers
Pre-signup validation, post-confirmation provisioning, custom messages, custom claims through the pre-token generation trigger, and the define, create, and verify challenge triggers when you need step-up or passwordless flows.
Token Handling Done Properly
JWT validation at the edge, sensible access token lifetimes, refresh token rotation and revocation, and Cognito authorizers on API Gateway or AppSync so your backend is not re-implementing checks by hand.
User Migration and Directory Consolidation
Moving off Auth0, Okta, Keycloak, Firebase, or a homegrown users table. We map attributes, run the migration trigger, keep both systems live during cutover, and give you a rollback path that does not lose accounts.
Testing, Monitoring, and Release Safety
Automated tests against real auth flows, CloudWatch alarms on sign-in failure spikes, and staged rollouts, because a bad auth deploy locks out every user at once. Built with our DevOps and quality engineering teams.

Our Customer Success Stories
Scalable IAM Platform for a Global Cybersecurity Company
Industry: Cybersecurity
Technical Stack: Zero-trust architecture, microservices, SSO, attribute-based access control, identity-as-a-service, real-time policy enforcement, hybrid and cloud-native deployment
This client sold security software, and its own identity platform had become the constraint. The legacy system lacked modern authentication methods and flexible policy controls, and compliance gaps across international deployments were holding back expansion into new markets. Our engineers rebuilt the platform on a zero-trust, microservices design with single sign-on, attribute-based access control, and real-time policy enforcement, then embedded monitoring for SOC 2, ISO 27001, and GDPR. The platform now runs at 99.9% availability with 80% faster enterprise onboarding, and the architecture is ready for passkeys and decentralized identity models.
CI/CD and Release Safety for a Leading IAM Solution
Industry: SaaS and identity management
Technical Stack: Amazon EKS, AWS CloudFormation, AWS CodePipeline, AWS CodeBuild, Amazon CloudWatch, AWS X-Ray, IAM roles, AWS KMS
Shipping changes to an identity product is unforgiving, because a bad release locks users out rather than degrading a feature. This SaaS identity provider was releasing on a multi-week cycle and carrying risk with every deployment. Our team containerized the services on EKS, defined the infrastructure in CloudFormation so environments matched, and automated the release path through CodePipeline and CodeBuild with security and compliance checks inside the pipeline. Disaster recovery drills run automatically against RTO and RPO targets. Deployment-related incidents dropped by 75%, and release cycles went from weeks to hours.
Designed for Enterprise Speed and Control
Auth work tends to sit in the backlog until a customer demands SSO. Here is the path from your first call to an engineer in your repository.
1. Share Your Requirements
Tell us where your users live today, which providers you need to federate with, your compliance obligations, and whether this is a new build or a migration. One call is usually enough.
2. Get Curated Profiles (Within 24 to 48 Hours)
You receive shortlisted AWS Cognito engineers with their identity project history, AWS certifications, and a note on how each one maps to your stack.
3. Evaluate and Interview
Run your own technical round. Ask how they would migrate 200,000 users without a password reset, or how they would add custom claims to a token. We encourage it.
4. Onboard and Kickoff (Within 48 to 72 Hours)
Accounts, repositories, IAM roles, and sprint goals get set up together. Most engineers are committing work inside the first week.
5. Continuous Support and Scaling
Add engineers, change the skill mix, or move to a managed team once the platform is stable. Handover documentation and notice periods are part of the agreement.
Our Hiring Models
Dedicated AWS Cognito Developers
Hire a dedicated AWS Cognito developer to own identity long term: pool design, federation onboarding for each new enterprise customer, token policy, and the security reviews that come with it. This fits when authentication is part of what you sell.
Team Augmentation With Remote AWS Cognito Developers
Hire remote AWS Cognito developers who work your hours, join your standups, and follow your review process. Many clients pair them with our AWS developers so platform and identity work move together.
Project-Based Engagement
A scoped piece of work: a user migration off Auth0 or a legacy database, an SSO rollout for enterprise customers, or an authentication security review. Larger replatforming runs with our application modernization specialists.
Industries Where Our AWS Cognito Developers Deliver Impact
Our team serves global clients across banking and financial services, healthcare, retail, manufacturing and supply chain, education, and information technology. Our identity engineers build the sign-in paths behind patient portals, customer accounts, partner dashboards, and internal tools, in sectors where a login failure is a compliance event as well as a support ticket.

Book a Free ConsultationFrequently Asked Questions
What does an AWS Cognito developer do?
An AWS Cognito developer builds and maintains the authentication and user management layer for an application. The work covers user pool and identity pool design, sign-up and sign-in flows, federation with SAML or OIDC providers, MFA, custom logic through Lambda triggers, and token validation in the backend. Most also handle user migrations and the security review that goes with them.
What skills should I look for when I hire AWS Cognito developers?
Look for someone who understands the standards underneath Cognito, not just its console. Ask them to explain the OAuth authorization code flow with PKCE, when they would use an identity pool rather than a user pool, how they add custom claims to a token, and how they would migrate users without forcing password resets. Node.js or Python, API Gateway, and infrastructure as code round out a strong profile.
How much does it cost to hire AWS Cognito developers?
Rates depend on seniority, engagement model, and whether the engineer owns identity long term or delivers a fixed scope such as an SSO rollout. Published rates for identity talent range widely, so compare on scope rather than the hourly figure. Budget Cognito separately, since it bills on monthly active users, with advanced threat protection priced on top. Entrans shares a rate card after a short requirement call.
Can you migrate our existing users into Cognito without forcing password resets?
Usually yes. Most identity providers will not let you export password hashes, so a bulk import cannot carry credentials across. The standard answer is just-in-time migration: a user migration Lambda trigger authenticates the person against your old system on their first sign-in, then creates the Cognito account silently. Users notice nothing, and you keep both systems live until the directory has drained.
Can we hire remote AWS Cognito developers who overlap with our team's hours?
Yes. You can hire remote AWS Cognito developers who work your business hours, join your standups, and take part in your on-call rotation. Entrans delivers from the US, UK, UAE, and India, so you can set the overlap you need, including a shifted schedule that covers your working day. Handover documentation and notice periods are written into the agreement.
