We are seeking a ArchitectBackend Engineer to design, build, and evolve a cloud-native platform built entirely on an AWS serverless and NoSQL architecture.
In this role, you will own event-driven services end to end, from data modeling and infrastructure definition to deployment and production support, working within a distributed engineering team that values autonomy and accountability.
The idóneo candidate is a seasoned Python engineer with deep, hands-on expertise in serverless design patterns and a proven track record of delivering scalable, resilient distributed systems in production.
You operate with a high degree of ownership and independence, make sound architectural trade-offs without close supervision, and communicate technical decisions clearly to both engineers and non-technical stakeholders.
You will be expected to raise the technical bar of the team through design input, code reviews, and mentoring.
Responsibilities
Architect and implement event-driven backend services, defining how components communicate asynchronously across the platform.
Design access patterns and single-table data models optimized for performance, scalability, and cost.
Define and maintain all cloud infrastructure as code, ensuring environments are reproducible, versioned, and consistent.
Build messaging, fan-out, and event routing flows that decouple services and handle failures gracefully through retries and dead-letter handling.
Own services end to end in production: monitoring, troubleshooting, incident response, and continuous performance and cost optimization.




Lead technical design discussions and document architectural decisions and trade-offs.
Review code and mentor other engineers on serverless best practices, testing and code quality.
Collaborate with product and engineering stakeholders to break down requirements into well-scoped, deliverable work.
Proactively identify technical debt, security risks, and scalability bottlenecks, and drive their resolution.
Must Have
7+ years of professional experience in backend software engineering.
Expert-level proficiency in Python in production environments.
Extensive hands-on experience with AWS Lambda, SQS, SNS, and EventBridge in production systems.
Strong experience designing and operating Amazon DynamoDB data models at scale.
Solid experience defining infrastructure with AWS CDK.
Demonstrated ability to work autonomously, own deliverables end to end, and make technical decisions independently.
Strong written and verbal communication skills, including the ability to explain technical trade-offs clearly.
Advanced English Level.
Based in LATAM.
Nice to have
Experience with AWS Step Functions and API Gateway.
Experience with observability tooling such as CloudWatch and AWS X-Ray.
Familiarity with CI/CD pipelines for serverless applications (e.g., GitHub Actions).
Experience writing CDK constructs in TypeScript.
AWS certification (Developer, Solutions Architect Associate/Professional).
Previous experience in startups or product companies working with US-based clients.
Bachelor's degree in Computer Science, Software Engineering, or a related field.
