We are seeking a skilled Senior Software Engineer to contribute to the full-stack design, development, and delivery of software solutions within a high-velocity engineering team. This role blends deep engineering excellence with a modern AI-first mindset — including the ability to rapidly prototype using GenAI platforms to accelerate team output and

innovation.

What You'll Do:

AWS Cloud, Serverless & Microservices Architecture

• Design and deliver cloud-native, microservices-based solutions on AWS, applying microservices principles across the full stack — frontend, backend, and cloud infrastructure — to build scalable, secure, and highly available systems, leveraging a broad and growing set of services including but not limited to:

• Compute: Lambda, Step Functions

• API, Auth & CDN: API Gateway, Cognito, CloudFront

• Messaging & Events: SQS, SNS, EventBridge, Kinesis

• Data: DynamoDB, S3, Aurora Serverless, OpenSearch, Kinesis Firehose

• Configuration: SSM Parameter Store

• Observability: CloudWatch, X-Ray

• IaC: CDK, SAM, CloudFormation

• And more across the broader AWS ecosystem

• Build and maintain scalable REST APIs using API Gateway and Lambda

• Support cloud cost optimization, security posture, and performance tuning efforts

• Implement CI/CD pipelines, infrastructure-as-code (AWS CDK/SAM), and blue/green deployment strategies

• Ensure production readiness through observability, automated testing, and monitoring

Full-Stack, Microservices & Cross-Platform Development

• Design, develop, test, and deploy full-stack applications and microservices across Flutter/Dart (mobile & cross-platform), React/JavaScript (web), and Python/Node.js/Java/Spring Boot (backend)

• Build responsive, performant web interfaces using React and JavaScript, ensuring seamless user experiences across devices

• Develop robust backend services and RESTful APIs using Java/Spring Boot, Python, and Node.js following microservices design principles

• Create and maintain cross-platform mobile and web applications using Flutter/Dart, delivering consistent experiences across iOS, Android, and web

• Apply microservices best practices including service decomposition, independent deployability, and fault tolerance across the full stack

AI-Assisted Engineering & Rapid Prototyping

• Rapidly prototype new product concepts using GenAI and LLM platforms

• Apply AI-assisted development tools to accelerate code generation, testing, documentation, and code review

• Evaluate AI-generated outputs for correctness, security, and production readiness

• Follow team-level standards and best practices for AI tool adoption

• Contribute to ideate → prototype → validate → ship cycles within fast-moving engineering teams

Collaboration & Mentorship

• Participate in code reviews and contribute to engineering best practices

• Support and mentor mid-level and junior engineers on design, cloud practices, and AI tool usage

• Promote a culture of quality, continuous improvement, and learning

Who You Are:

• Bachelor’s degree (list any requirements of discipline here) and 4 years’ experience in a related field. The right candidate could also have a different combination, such as a master’s degree and 2 years’ experience; a Ph.D. and up to 1 year of experience; or 16years’ experience in a related field.
• Applicants must currently be authorized to work in the United States for any employer without current or future sponsorship. No OPT, CPT, STEM/OPT or visa sponsorship now or in future.
• Strong full-stack proficiency across mobile/cross-platform (Flutter/Dart), web (React/JavaScript), and backend (Python, Node.js, Java/Spring Boot).
• Hands-on AWS experience across a broad range of services including but not limited to Lambda, API Gateway, DynamoDB, Kinesis, OpenSearch, S3, Firehose, EventBridge, and SSM.
• Experience with CI/CD, infrastructure-as-code, and serverless deployment patterns.
• Demonstrated use of AI/GenAI tools in a professional development setting; understanding of prompt engineering, context management, and AI tool limitations.
• Familiarity with AWS CDK or SAM for infrastructure provisioning is a plus.
• Exposure to agentic AI workflows and multi-agent systems is a plus.
• AWS certification (Solutions Architect, Developer, or equivalent) is a plus.
