Interns typically work under the supervision of experienced developers and contribute to real-world projects while learning industry-standard technologies such as HTML, CSS, JavaScript, and various frameworks. This role helps interns develop their technical skills, understand workplace dynamics, and build a portfolio of work for future employment opportunities.

As a Web Developer Intern, you can expect to work on a variety of tasks such as coding website features, fixing bugs, assisting with front-end and back-end development, and participating in team meetings. You'll likely collaborate closely with senior developers and designers, gaining hands-on experience with technologies like HTML, CSS, JavaScript, and possibly frameworks like React or Angular. Interns are often encouraged to ask questions, contribute ideas, and gradually take on more complex assignments as they build confidence. This role offers a great opportunity to learn best practices, develop coding skills, and understand how web development projects are managed in a professional environment.

These abilities enable interns to quickly learn, adapt, and contribute meaningful code to real-world projects.

Can I be a web developer intern with no experience?

Job description

About us
At Sierra, we're building a platform to enable every company in the world to build better, more human customer experiences with AI. We partner with industry leaders such as SoftBank, Uber, Rivian, CLEAR, and Sutter Health. We are primarily an in-person company based in San Francisco, with growing offices across North America, Europe, and Asia.
We are guided by a set of values that are at the core of our actions and define our culture: Trust, Customer Obsession, Craftsmanship, Intensity, and Family. These values are the foundation of our work, and we are committed to upholding them in everything we do.
Our co-founders are Bret Taylor and Clay Bavor. Bret currently serves as Board Chair of OpenAI. Previously, he was co-CEO of Salesforce (which had acquired the company he founded, Quip) and CTO of Facebook. Bret was also one of Google's earliest product managers and co-creator of Google Maps. Before founding Sierra, Clay spent 18 years at Google, where he most recently led Google Labs. Earlier, he started and led Google's AR/VR effort, Project Starline, and Google Lens. Before that, Clay led the product and design teams for Google Workspace.
What You'll Do:
  • Own frontend across product and marketing surfaces: You will work across both our core product interface and customer-facing web pages, ensuring a cohesive, polished user experience across all touch points. This includes building features in the web app and also collaborating on our website to keep branding and user experience consistent and high-quality.
  • Build content infrastructure that unblocks the team: You'll develop our CMS (we use Sanity) to give content and marketing teams self-serve tooling, structured content models, and preview/staging workflows, so routine changes don't depend on engineering. You'll design content schemas and editing experiences that let non-engineers move quickly and confidently.
  • Champion growth: You'll partner with marketing, sales, and operations to implement analytics and enable experimentation, turning business goals into shipped, instrumented features so we always know what's actually working.
  • Make localization first-class: You'll support localization and internationalization - multilingual content, translation workflows, and the infrastructure behind them, so non-English experiences are genuinely first-class rather than afterthoughts.
  • Treat performance as a feature: You'll own Core Web Vitals, media and asset optimization, and the diagnosis of the subtle issues: layout shift, lazy-loading, video quality, render timing. You care about speed, and you measure it.
  • Hold a high bar for accessibility: You'll champion semantic markup, keyboard navigation, screen-reader support, and WCAG-minded component design, ensuring the site is usable by everyone who visits it.
What You'll Bring:
  • Marketing and growth fluency: You've worked on marketing or growth-facing web before, and you understand the business context - funnels, conversion, SEO, analytics, and A/B testing-not just the code. We care about this more than years of experience or exact seniority.
  • Strong frontend fundamentals: You're fluent in modern JavaScript and TypeScript and React (or a similar framework), with a real sense for UI/UX craft and an instinct for getting the small details right.
  • A genuine commitment to performance and accessibility: You care about both deeply and can point to specific, concrete things you've done to improve them in production.
  • Comfort with structured content: You've worked with a headless CMS and structured content models before. Sanity experience is a plus.
  • Strong cross-functional collaboration: You work well with non-engineers - designers, content writers, and marketers - and can translate their goals into technical work, and technical tradeoffs back into terms they can act on.
Even Better...
  • Localization and i18n experience: You've worked with internationalization systems and translation tooling before.
  • Analytics and experimentation depth: You're familiar with web analytics and experimentation platforms and know how to use them to drive decisions.
  • Third-party integration experience: You've integrated services like video hosting or error monitoring into a content workflow.
Our values
  • Trust: We build trust with our customers with our accountability, empathy, quality, and responsiveness. We build trust in AI by making it more accessible, safe, and useful. We build trust with each other by showing up for each other professionally and personally, creating an environment that enables all of us to do our best work.
  • Customer Obsession: We deeply understand our customers' business goals and relentlessly focus on driving outcomes, not just technical milestones. Everyone at the company knows and spends time with our customers. When our customer is having an issue, we drop everything and fix it.
  • Craftsmanship: We get the details right, from the words on the page to the system architecture. We have good taste. When we notice something isn't right, we take the time to fix it. We are proud of the products we produce. We continuously self-reflect to continuously self-improve.
  • Intensity: We know we don't have the luxury of patience. We play to win. We care about our product being the best, and when it isn't, we fix it. When we fail, we talk about it openly and without blame so we succeed the next time.
  • Family: We know that balance and intensity are compatible, and we model it in our actions and processes. We are the best technology company for parents. We support and respect each other and celebrate each other's personal and professional achievements.
What we offer
We want our benefits to reflect our values and offer the following to full-time employees:
  • Flexible (unlimited) paid time off
  • Medical, dental, and vision benefits for you and your family
  • Life insurance and disability benefits
  • Retirement plan dependent on country of employment
  • Parental leave
  • Fertility and family building benefits through Carrot
  • Lunch, as well as delicious snacks and coffee to keep you energized
  • Discretionary benefit stipend giving people the ability to spend where it matters most
  • Free alphorn lessons

These benefits are further detailed in Sierra's policies, may vary by region, and are subject to change at any time, consistent with the terms of any applicable compensation or benefits plans. Eligible full-time employees can participate in Sierra's equity plans subject to the terms of the applicable plans and policies.
Be you, with us
We're working to bring the transformative power of AI to every organization in the world. To do so, it is important to us that the diversity of our employees represents the diversity of our customers. We believe that our work and culture are better when we encourage, support, and respect different skills and experiences represented within our team. We encourage you to apply even if your experience doesn't precisely match the job description. We strive to evaluate all applicants consistently without regard to race, color, religion, gender, national origin, age, disability, veteran status, pregnancy, gender expression or identity, sexual orientation, citizenship, or any other legally protected class.
