Job summary

Vynyl, LLC in Austin, TX seeks a Senior Full Stack Developer to lead the full software lifecycle—from design to deployment and monitoring—building robust backend services with Python and AWS serverless tech. A strong fluency with AI-enabled development tools will be essential for driving secure, scalable solutions.

You will architect event-sourced pipelines, collaborate with product teams, and implement infrastructure-as-code while mentoring engineers and shaping architectural direction.

Qualifications

• 5+ years of professional experience in full-stack software development.
• Expert-level proficiency in Python for backend development (Django).
• Strong working proficiency with Vue.js (and TypeScript).
• Deep practical experience designing, deploying, and maintaining applications using serverless architectures (AWS Lambda, API Gateway, managed services).
• Proficiency with SQL, preferably PostgreSQL.
• Solid understanding of event sourcing and event-driven architecture patterns (message brokers or streaming services such as SQS, SNS, EventBridge, or Kinesis).
• Experience with CI/CD pipelines, automated testing, and Infrastructure-as-Code.
• Demonstrated fluency in AI-assisted development: hands-on use of AI-powered coding tools with productivity gains, understanding risks.

Responsibilities

• Design and implement scalable, cost-efficient backend services using Python and AWS (Lambda, API Gateway, RDS, DynamoDB, SQS, EventBridge).
• Architect and build event-sourced systems and event-driven pipelines with reliable message processing and idempotency.
• Collaborate with product managers and designers to translate requirements into technical designs and shippable code.
• Implement best practices for security, logging, monitoring, and infrastructure-as-code (Terraform or CloudFormation).
• Perform rigorous code reviews, mentor junior and mid-level engineers, and drive technical excellence across the team.
• Actively research, propose, and integrate new technologies to optimize development velocity and system performance.
• Clearly articulate a professional viewpoint on integrating AI tools securely, ethically, and effectively into the software lifecycle.

Job description

Vynyl's technologists, designers and product strategists are experts at system modernization, new product development, and rescuing projects in distress. We use the best cloud-native and AI-enabled tools, and apply a battle-tested combination of Agile, Lean, and design thinking to collaboratively solve our client's most pressing challenges - and do it right the first time. We often work in regulated industries, such as healthcare, financial services, government and education. Our work helps detect diseases, identify kids who need special educational support, applies AI to support complex legal settlements, helps people access mental health services, and so much more.

The Role

As a Senior Full Stack Developer, you will be a key leader across the entire software development lifecycle, from conceptual design to deployment and monitoring. You will be responsible for building robust, scalable backend services using Python and AWS Serverless technologies (Lambda, DynamoDB, SQS, EventBridge), developing event-sourced systems that provide complete state history and auditability. A critical component of this role is a demonstrated fluency with modern AI/ML development tools (e.g., GitHub Copilot, Claude Code, agentic coding tools, large language models). We are looking for candidates who not only use these tools daily but can articulate a clear, thoughtful perspective on their limitations, security implications, and the strategic opportunities they create for the engineering profession.

Key Responsibilities

• Design and implement highly scalable, cost-efficient backend services using Python and AWS (Lambda, API Gateway, RDS, DynamoDB, SQS, EventBridge).
• Architect and build event-sourced systems and event-driven pipelines, ensuring reliable message processing, idempotency, and eventual consistency across distributed services.
• Collaborate with product managers and designers to translate requirements into technical designs and shippable code.
• Implement best practices for security, logging, monitoring, and infrastructure-as-code (e.g., Terraform or CloudFormation).
• Perform rigorous code reviews, mentor junior and mid-level engineers, and drive technical excellence across the team.
• Actively research, propose, and integrate new technologies and patterns, with a focus on optimizing development velocity and system performance.
• Clearly articulate a professional point of view on how to effectively, securely, and ethically integrate AI tools into the software development lifecycle.

Qualifications

Required

• 5+ years of professional experience in full-stack software development.
• Expert-level proficiency in Python for backend development (including Django).
• Strong working proficiency with Vue.js (and typescript).
• Deep practical experience designing, deploying, and maintaining applications using serverless architectures (preferably AWS Lambda, API Gateway, and managed services).
• Proficiency with SQL, preferably PostgreSQL.
• Solid understanding of event sourcing and event-driven architecture patterns, including experience with message brokers or streaming services (e.g., SQS, SNS, EventBridge, or Kinesis).
• Experience with CI/CD pipelines, automated testing, and Infrastructure-as-Code.
• Demonstrated Fluency in AI-Assisted Development: Candidates must be able to demonstrate practical, hands-on experience using AI-powered coding tools to achieve specific, quantifiable productivity gains, while also clearly understanding and mitigating the associated risks (e.g., code quality, security, IP concerns).

Nice to Have

• Experience with advanced AWS services (e.g., Step Functions, Kinesis, SageMaker).
• Experience working in a regulated or compliance-focused environment.
• A Bachelor's or Master's degree in Computer Science or a related technical field.

AI and the Evolution of Software Engineering & Ops

All candidates must be prepared to discuss and demonstrate the following during the interview process:

• Practical AI Tool Usage: Specific examples of AI tools used in professional or personal projects to enhance productivity, solve complex problems, or accelerate development. If you have a preferred agentic tool setup, please share!
• Understanding of AI Limitations: A clear understanding and articulation of the current technical, ethical, and accuracy limitations of modern AI tools in the engineering context.
• Strategic AI Opportunity: A viewpoint on how AI tools create new opportunities for software engineering, such as shifting focus from boilerplate code to complex problem-solving or architectural design.
• Evolution of the Engineering Role: A well-articulated point of view on how your role has already changed (e.g., new workflows, skills, ways of collaborating) due to the introduction of AI and how you expect the role to evolve in the coming years based on your assessment of coming advancements in AI tools and technologies.

Salary Range $140,000 - $175,000
