What is a Freelance Full Stack Developer job?

A Freelance Full Stack Developer is a self-employed professional who builds both the front-end and back-end of websites or applications. They work with various technologies, including databases, servers, APIs, and client-side interfaces, to create fully functional digital products. Unlike full-time employees, freelancers work on a project basis for multiple clients, offering flexibility in workload and schedule. Their responsibilities often include coding, debugging, deployment, and sometimes design.

What types of projects and clients can Freelance Full Stack Developers typically expect to work with?

Freelance Full Stack Developers often engage with a diverse range of projects, including website and web application development, e-commerce platforms, mobile app backends, and API integrations. Clients can range from startups and small businesses to established companies and entrepreneurs seeking bespoke digital solutions. The variety in clients and project scopes allows developers to constantly expand their skills and work experience, but it also means adapting quickly to new industries and client expectations. Freelancers typically manage their own workflow, communicate directly with clients, and are responsible for project timelines, making this role ideal for self-motivated technology professionals.

What are the key skills and qualifications needed to thrive in the Freelance Full Stack Developer position, and why are they important?

To thrive as a Freelance Full Stack Developer, you need a solid grasp of both front-end and back-end programming languages (such as JavaScript, HTML/CSS, Node.js, Python, or similar) and a strong portfolio showcasing completed projects. Familiarity with frameworks like React or Angular, version control systems like Git, cloud services, and sometimes relevant certifications (such as AWS Certified Developer) are highly valued. Excellent communication, problem-solving abilities, time management, and client relationship skills help set freelancers apart. These competencies are crucial for effectively delivering end-to-end solutions, managing multiple projects, and building a reliable client base.

Job description

About Us
Foundry Robotics is building an AI-native robotics manufacturing company focused on deploying advanced assembly and production capability for leading robotics companies and national-security-critical hardware. Basically, we're building robots that build robots.
Factory OS is building software that runs factories. Our platform spans cloud backends, on-prem services, and edge devices deployed on the factory floor. The operators, supervisors, and managers who use our tools need interfaces that are fast, reliable, and intuitive-even when network conditions aren't perfect and the environment is demanding.
The Role
We are hiring a Sr Full-Stack Developer to build end-to-end features across the Factory OS web and edge applications. You will work from responsive frontends to backend APIs, delivering software that runs both in the cloud and directly on factory-floor edge devices. You will ship features that real operators use every day to run production lines.
Key Responsibilities
Full-Stack Feature Development
  • Develop and ship features across web and edge-deployed applications using modern frontend frameworks and backend services
  • Build responsive, intuitive user interfaces for factory operators, supervisors, and managers
  • Design backend APIs and services that support both cloud and edge deployment targets
  • Ship production-grade systems end-to-end

Edge + Reliability
  • Implement offline-capable and low-latency features for edge environments with intermittent connectivity
  • Design systems that tolerate degraded network modes and factory-floor conditions
  • Write comprehensive tests (unit, integration, E2E) and participate in code reviews

Collaboration + Platform
  • Collaborate with designers, product managers, and backend engineers to deliver cohesive user experiences
  • Contribute to shared libraries, component systems, and developer tooling used across Factory OS
  • Troubleshoot and resolve production issues across the full stack

What We're Looking For
  • 4+ years of professional full-stack development experience, building and shipping real production software
  • Strong proficiency in a modern frontend framework (React, Vue, or Svelte) and TypeScript
  • Backend experience with Node.js, Python, Go, or a similar server-side language
  • Understanding of RESTful and/or GraphQL API design
  • Comfort with relational databases, caching layers, and message queues
  • Experience deploying applications to cloud platforms (AWS, GCP, or Azure)
  • Comfortable operating independently in a fast-paced, cross-functional environment
Nice to Have (Not Required)
  • Experience building progressive web apps (PWAs) or offline-first applications
  • Familiarity with Docker, Kubernetes, or edge computing frameworks
  • Exposure to manufacturing, logistics, or industrial environments
Growth Opportunities
  • Own major product surfaces used by factory teams every day
  • Gain deep exposure to edge computing and industrial software patterns
  • Influence frontend architecture and developer experience across the platform
  • Grow into technical leadership within the application team
Why Join Us?
This is one of the only places where world-class manufacturing operators, mechanical engineers, robotics researchers, and software engineers sit in the same room - building production systems together.
We are committed to being deeply embedded in the U.S. industrial base. Our focus is simple: build adaptive robotic assembly systems that make American manufacturing scalable, resilient, and competitive again.
If you want to run a mature, well-defined commercial org, this may not be the role.
If you want to build the commercial engine that brings AI-driven manufacturing to every industrial and energy customer in America - this is it.
The base salary range for this full-time position in the location of San Francisco is:
$150,000-$250,000 USD
Compensation packages at Foundry Robotics for eligible roles include base salary, equity, and benefits. The range displayed on each job posting reflects the minimum and maximum target for new hire salaries for the position, determined by work location and additional factors, including job-related skills, experience, interview performance, and relevant education or training. Foundry Robotics employees in eligible roles are also granted equity based compensation, subject to Board of Director approval. You'll also receive benefits including, but not limited to: Comprehensive health, dental and vision coverage, and generous PTO.
