Hire Dedicated AWS Lambda Developers
for USA Projects
AWS Lambda is Amazon's serverless compute service — it runs your code in response to events without you provisioning or managing servers, scaling automatically and billing only for the compute time actually used. Through Eternal, you can readily scale your business and operations by hiring dedicated AWS Lambda developers and consultants. We are a professional and official AWS Consulting Partner for AWS development, integration, and migration services. Every Lambda developer on our team is AWS-certified, experienced in event-driven architectures, and ready to integrate seamlessly into your USA engineering workflow.
You can also try our free technology consulting to review our AWS Lambda expertise — covering serverless REST APIs, event-driven data processing, Step Functions orchestration, and infrastructure-as-code deployments built for enterprise-grade reliability.
Expert Lambda Developers for Event-Driven, Serverless AWS Applications
Our AWS Lambda developers deliver flexible, production-ready serverless solutions — from HTTP APIs behind API Gateway to background processing triggered by S3 uploads, DynamoDB Streams, SQS queues, SNS topics and EventBridge rules. Whether you need a single Lambda function or a full event-driven architecture spanning dozens of functions, our team covers the full Lambda development lifecycle: design, build, test, deploy and operate.
Our Lambda engineers ensure you get enterprise-grade reliability from serverless compute — leveraging automatic scaling, built-in fault tolerance and pay-per-execution pricing to keep costs proportional to actual usage. We specialise in AWS Step Functions for multi-step orchestration, Lambda layers for shared code, provisioned concurrency and SnapStart for cold-start reduction, and infrastructure-as-code deployments with AWS SAM, AWS CDK and the Serverless Framework — designed to scale seamlessly for USA businesses.

Why AWS Lambda
Why Choose Lambda for Your
Serverless Application
Our Lambda teams simplify the use of AWS services by pairing serverless strengths with the components your project actually needs — from event source design and IAM permissions to observability and cost control.
No Server Management
AWS provisions, patches and manages the underlying compute — your team focuses on code, not infrastructure.
Automatic Scaling
Lambda scales from zero to thousands of concurrent executions automatically, matching demand without manual intervention.
Pay Only for What You Use
Billing is based on execution time and requests — there is no cost for idle capacity, unlike always-on servers.
Faster Time to Market
No servers to provision means teams ship new features and APIs faster, with less operational overhead upfront.
Native AWS Integration
Lambda connects natively to over 200 AWS services and event sources, from S3 and DynamoDB to Kinesis and EventBridge.
Multi-Language Support
Write functions in Node.js, Python, Java, Go, .NET, Ruby or any language via custom runtimes and container images.
Built-In Fault Tolerance
Lambda runs across multiple Availability Zones by default, with automatic retries for asynchronous invocations.
Reduced Operational Overhead
No patching, capacity planning or server monitoring — your team spends time on features instead of upkeep.

Large scale MongoDB development delivering multi type content within complex collections with embedded typing and logic and in multiple languages on AWS. Technically complex but delivered faultlessly. Thanks everyone at Eternal, job very well done!
Richard P.Bournemouth, GB
★★★★★
The Eternal team did an excellent job setting up our application. It was a complex scenario with several legacy issues, but they worked swiftly and communication was excellent, all managed through a very helpful online project management system. I will definitely be using them again in the future

FAQs on Hiring
AWS Lambda Developers
Q
What is AWS Lambda and why would I hire a developer for it?
AWS Lambda is Amazon's serverless compute service — it runs your code in response to events (an HTTP request, a file upload, a database change, a schedule) without you provisioning or managing any servers, and you pay only for the compute time you actually use. Hiring a specialist AWS Lambda developer matters because getting the most out of Lambda requires experience with event source design, cold-start optimisation, IAM least-privilege permissions and cost-aware architecture — mistakes here are easy to make and expensive to unwind later.
Q
How do I hire certified AWS Lambda developers for my project?
To hire certified AWS Lambda developers from Eternal, submit your project requirements via our contact form, discuss scope and timeline with our team, choose an engagement model (hourly, part-time or full-time), interview shortlisted candidates, and onboard within 3–5 business days. Eternal is an AWS Consulting Partner serving USA businesses.
Q
What AWS services and tools do your Lambda developers specialise in?
Our AWS Lambda developers are expert in API Gateway, Step Functions, EventBridge, SQS, SNS, DynamoDB Streams, Kinesis, S3 event triggers, Lambda layers, Lambda@Edge, provisioned concurrency, and infrastructure-as-code tools including AWS SAM, AWS CDK, the Serverless Framework and Terraform. They build across Node.js, Python, Java, Go and .NET runtimes.
Q
What is the cost to hire a dedicated AWS Lambda developer?
The cost to hire an AWS Lambda developer from Eternal depends on the engagement model (hourly, part-time or full-time), project complexity, and required seniority. We offer transparent, competitive pricing with no hidden costs. Contact us for a tailored quote.
Q
Can your Lambda developers help reduce cold start latency?
Yes. Our Lambda developers optimise cold starts through provisioned concurrency, smaller deployment packages, Lambda SnapStart, careful runtime and memory sizing, and connection reuse patterns — reducing latency for user-facing and time-sensitive Lambda functions.
Q
Can I hire a Lambda developer to orchestrate multi-step workflows?
Yes. Eternal's Lambda developers design and build AWS Step Functions state machines to orchestrate multi-step, long-running or error-prone workflows across multiple Lambda functions — with built-in retries, error handling and visual execution tracking.
Q
Are your AWS Lambda developers CCPA compliant?
Yes. Eternal's AWS Lambda developers follow CCPA compliance for California-based clients and align with other US state privacy laws. We use AWS data residency controls, encryption at rest and in transit, IAM least-privilege permissions, and sign NDAs to protect all client data and intellectual property.
Q
How quickly can I onboard an AWS Lambda developer from Eternal?
You can onboard a dedicated AWS Lambda developer from Eternal in as little as 3–5 business days. Our streamlined hiring process covers requirement submission, team briefing, candidate shortlisting, a technical interview, and rapid onboarding — designed for USA business timelines.
Q
Can I scale my AWS Lambda development team up or down as needed?
Yes. Eternal offers fully flexible team scaling. Start with one Lambda developer and expand to a full team as your project grows, or reduce resources after a major release. All engagement models — hourly, part-time and full-time — support flexible scaling with no long lock-in periods.
Q
Why choose an AWS Consulting Partner for Lambda development over a freelancer?
Hiring through an AWS Consulting Partner like Eternal means you get AWS-certified Lambda developers validated by Amazon, backed by a team rather than a single contractor, with guaranteed delivery, NDA protection, 100% IP ownership, CCPA compliance, and direct access to AWS support and best-practice architecture guidance.
