ResponsibilitiesDeveloping features, optimizing performance, collaborating with designers and backend teamsAssisting in coding, fixing bugs, learning project workflows
Work EnvironmentIndependent task handling, code reviews, team collaboration

The Mid Frontend Developer typically has more experience and handles complex tasks independently, while the Junior Frontend Developer focuses on learning, assisting, and gaining foundational skills. The mid-level role requires a deeper understanding of frameworks and project workflows, making it suitable for those with some professional experience in frontend development.

What is a mid frontend developer?

Mid Frontend Developers are professionals who specialize in building and maintaining the user-facing parts of web applications, typically with 2-4 years of experience. They are responsible for translating design mockups into interactive websites or apps using technologies like HTML, CSS, and JavaScript frameworks such as React, Angular, or Vue.js. Their role often involves collaborating with designers and backend developers, optimizing applications for speed and responsiveness, and ensuring cross-browser compatibility. Unlike junior developers, mid-level developers are expected to work more independently, solve moderately complex problems, and contribute to code reviews and project planning.

What are some common challenges faced by mid frontend developers when working on cross-functional teams?

Mid-level frontend developers often collaborate with backend developers, designers, and product managers, which can sometimes lead to challenges in communication and aligning on project requirements. Balancing the need for delivering visually appealing, responsive interfaces while ensuring performance and accessibility can also be demanding. Additionally, adapting to evolving frameworks or integrating new tools as decided by the team may require continuous learning and flexibility. Successful mid-level frontend developers proactively seek feedback, clarify requirements early, and stay updated on best practices to navigate these challenges.

What are the key skills and qualifications needed to thrive as a mid frontend developer?

To thrive as a Mid Frontend Developer, you need strong proficiency in HTML, CSS, and JavaScript, along with experience in modern frameworks like React, Angular, or Vue and a relevant degree or equivalent experience. Familiarity with version control systems (such as Git), build tools, and UI design libraries is commonly expected. Strong problem-solving, effective communication, and a collaborative mindset help you stand out in team settings. These skills ensure you can create high-quality, user-friendly interfaces that work well in dynamic, cross-functional development environments.

Job description

Position Summary

Samsung, a world leader in advanced semiconductor technology, is founded on a simple philosophy - the endless pursuit of excellence will create a better world for all. At Samsung Austin Research and Development Center (SARC) and Advanced Computing Lab (ACL), we are building a center of excellence for Intellectual Property (IP) that is applied to high-performance computing devices (mobile, automotive, and other custom market segments) consumed by millions of people around the world. Come build with us!

Role and Responsibilities

As a Staff GPU Front-End Implementation Methodology Engineer, you will shape and advance the front-end implementation methodologies that underpin high-quality, scalable RTL across complex GPU and SoC designs. Working as a mid-to-senior individual contributor, you will serve as a key enabler for design and verification teams - helping them work faster, with greater confidence, and at scale.

You will partner closely with architecture, verification, CAD, and physical design groups to define and uphold best practices, design guidelines, and quality standards that align with high-performance and low-power goals. You will own and evolve the RTL flow and build system, including support for an agentic AI workflow, and contribute to a broader portfolio of software initiatives: the RTL CI/CD system, operational metrics collection and reporting, custom web application development, and open-source tool provisioning.

In this role, you will:

  • Empower design and DV teams to work efficiently by removing friction from front-end workflows and proactively addressing methodology gaps
  • Drive front-end RTL implementation methodologies for GPU and SoC designs, ensuring scalability, architectural alignment, and adherence to performance and power objectives
  • Take ownership of moderate-to-complex projects, leading efforts to advance best practices and staying ahead of industry trends and emerging technologies

Skills and Qualifications

  • 6+ years of experience with a Bachelor's Degree in Computer Science/Engineering, or 4+ years of experience with a Master's Degree, or 2+ years of experience with a Ph.D.
  • Hands-on experience designing and building agentic AI tools and workflows
  • Proficiency across a broad range of Unix/Linux programming languages, including Python, C++, Perl, Ruby, Go, and shell scripting
  • Deep Linux system expertise, including debugging complex system-level issues
  • Solid background in DevOps practices, build automation, and build systems, including GNU Make
  • Experience with containerized environments and orchestration platforms, including Docker, Kubernetes, and OpenShift
  • Strong analytical and problem-solving skills with a methodical approach to debugging
  • Excellent written and verbal communication skills, with a track record of producing clear technical documentation, design specs, and methodology guides
  • Proven ability to collaborate effectively across global, cross-functional teams and thrive in fast-paced, ambiguous environments
  • Familiarity with RTL design concepts and testbench environments is a plus

Our Team

The GPU Project and RTL team at SARC/ACL owns the microarchitecture development of features for Samsung's current and next-generation mobile GPU IPs. Our work spans core RTL design, front-end implementation, and the infrastructure needed to deliver scalable, production-ready designs. Through cross-functional collaboration, we translate architectural concepts into high-quality RTL that delivers market-differentiating performance and energy efficiency. Our Xclipse GPU is the industry's first mobile GPU with hardware ray tracing technology, enabling console-level graphics on Samsung Galaxy smartphones.

You will join a diverse, highly collaborative organization working across concurrent-development cycles, with direct impact on consumer technologies used worldwide. Here you'll help build what's next, experiment with new ideas and explore different GPU development verticals, broaden technical expertise, and solve impactful challenges in a supportive environment that values collaboration, continuous learning, and growth.
