What is a founding full stack software engineer?

Founding Full Stack Software Engineers are technical professionals who join a startup at its earliest stages to help build and shape the company's core products and technology infrastructure. They work across both the front-end and back-end of applications and play a key role in making architectural decisions, setting up development processes, and establishing the technical foundation. As 'founding' team members, they often have greater responsibilities, including working closely with company founders, contributing to product strategy, and sometimes receiving equity or a stake in the company.

What unique challenges might I face as a founding full stack software engineer in an early-stage startup?

As a Founding Full Stack Software Engineer, you’ll often juggle multiple responsibilities, from designing core architecture to deploying code and setting up development workflows. Since resources are limited and the product vision can evolve quickly, adaptability and strong communication with founders and other early team members are key. You may also be deeply involved in decisions beyond pure engineering, such as hiring, product strategy, and even customer support. This environment can be both demanding and highly rewarding, offering accelerated learning and significant influence over the company’s technical direction.

Key Responsibilities
  • API Development: Design, develop, and maintain robust, secure, and scalable APIs that integrate with various services and platforms.
  • Full Stack Development: Build responsive and high-performance front-end and back-end applications using modern frameworks (Java, React, Node.js, etc.).
  • Automated Test Development: Develop API and microservices tests (including contract testing and service virtualization) and UI tests using modern test automation tools and frameworks.
  • Cloud-Native Architecture: Design and implement scalable, cloud-native applications on AWS, using best practices for security, reliability, and performance.
  • Containerization: Create and manage applications deployed using various container runtimes (Lambda, Amazon ECS/EKS, Kubernetes, etc.).
  • Distributed Systems: Design and develop scalable, distributed systems that support high availability and resilience.
  • Event-Driven Architecture: Implement event-driven architectures using tools such as Apache Kafka, Amazon SNS/SQS, or similar technologies to enable real-time data processing and asynchronous communication.
  • Microservices: Design and maintain microservices-based applications that can be deployed, scaled, and updated independently.
  • Unit Testing: Write and maintain comprehensive unit tests for both front-end and back-end applications to ensure code quality and stability.
  • CI/CD Pipelines: Build and maintain continuous integration and continuous deployment (CI/CD) pipelines (e.g., GitHub Actions, GitLab Pipelines, Jenkins, Bitbucket Pipelines).
  • Database Design & Optimization: Design and optimize databases, working with both relational (e.g., PostgreSQL, MySQL) and NoSQL databases (e.g., DynamoDB).
  • Collaborate: Work closely with product managers, UX/UI designers, and other engineers to deliver high-quality products in a timely manner.
  • Code Reviews: Participate in code reviews, providing constructive feedback and ensuring high standards for code quality and maintainability.
Skills and Qualifications
  • Work Authorization: Must be legally authorized to work in the United States without employer sponsorship.
  • Location Requirement: Must be a resident of the continental United States.
  • 8+ years of experience as a Full Stack Software Engineer or in a similar role.
  • Strong proficiency in API development (REST, GraphQL).
  • Expertise in Docker and container orchestration tools (Kubernetes, AWS ECS/EKS).
  • Proven experience with AWS Cloud Services (e.g., EC2, Lambda, RDS, S3, CloudFormation).
  • Experience in designing and working with distributed systems and event-driven architecture.
  • Strong programming skills in Java, JavaScript/TypeScript (React, Node.js), or similar languages (e.g., Python, Go).
  • Experience with unit testing frameworks (e.g., Jest, Mocha, JUnit) for front-end and back-end applications.
  • Experience building and maintaining CI/CD pipelines (e.g., GitHub Actions, GitLab Pipelines, Jenkins, Bitbucket Pipelines).
  • Experience with relational and NoSQL databases (e.g., PostgreSQL, MySQL, MongoDB, DynamoDB).
  • Solid understanding of DevOps practices and tools (CI/CD pipelines, Infrastructure as Code, monitoring).
  • Familiarity with front-end development using modern frameworks (e.g., React, Angular, Vue.js).
  • Familiarity with microservices architecture and serverless technologies (e.g., AWS Lambda, API Gateway).
  • Knowledge of security best practices and performance optimization in cloud environments.
  • Strong problem-solving skills, with the ability to troubleshoot complex technical issues.
  • Experience with Agile development methodologies.
  • Excellent communication and collaboration skills.
Compensation

$125–$150/hour with full benefits, including:

  • 401(k) with employer matching 6%
  • Health, dental, and vision insurance
