Junior Frontend Engineer

About the role

The role shapes the frontend foundation for a large consumer platform, working with senior engineers to turn product vision into production code. You accelerate your learning curve while contributing to the codebase that serves millions of users. The position focuses on hands-on development, mentorship, and collaboration across product and engineering teams.

Software engineers turn product ideas into working code. Engineers work in small teams, review each other's work, and ship in small batches. Most teams follow agile practices such as sprints and daily standups. Engineers also write tests, fix bugs, and improve performance. The field values clear communication as much as technical skill. Engineers spend part of every week on planning, code review, and debugging, not just writing new code. The ability to explain a technical decision in plain words separates strong engineers from the rest.

Key facts

What you'll do

React components and user interfaces are built and refined using React and TypeScript, guided by senior engineers.

Scalable and maintainable frontend architecture is created to support long term product goals.

External services for experimentation and feature control are integrated to enable data driven decisions.

Cross functional workflows with backend and product teams are coordinated to align implementation with business objectives.

Every day AI tools such as Claude, Cursor, and Copilot are used to support development workflows.

Requirements

Two or more years of professional experience with React and TypeScript through work, bootcamps, internships, or personal projects is required.

Interest in JavaScript backends like NestJS is required to collaborate effectively on end to end features.

Clean and testable code is written with a focus on performance and quality best practices.

An eye for design is used to build polished and user friendly interfaces.

Exposure to React Native is a plus that can strengthen cross platform efforts.

Practical notes

The role is based onsite in Berlin, and the successful contributor works within a fast moving, high impact environment.

Equal opportunity applies, and diversity across backgrounds is encouraged.

Typical interview steps

Hiring for engineering roles usually starts with a recruiter screen, followed by one or two technical rounds. Candidates often solve a coding problem, discuss past projects, and answer system design questions. Some loops include a take-home task. Final rounds typically cover team fit and give candidates a chance to ask questions. Interviewers look for how you break down an unfamiliar problem, not just whether you reach the answer. Practicing a few problems aloud and reviewing your own past projects are the best preparation.

Good to know

Modern frontend development relies heavily on React and TypeScript for type safe and maintainable interfaces.

AI assisted tools are increasingly used to speed up development and code quality in contemporary teams.

Design sensitivity helps bridge the gap between product concepts and technical implementation.

Cross functional collaboration aligns engineering output with business priorities.

Performance optimization ensures responsive and efficient user experiences.

Questions to ask

Worth asking in any interview: how the team measures success, who the role works with daily, what the onboarding looks like, and what the company is trying to achieve this year. Asking what past hires did well is a strong final question. Keep the list short and pick the questions that matter most to you.

Career growth

Engineering careers usually progress from individual contributor to senior, staff, and principal levels. Some engineers move into management and lead teams of five to twenty people. Others stay on the technical track. Growth follows demonstrated impact, not tenure alone. A typical engineering ladder has clear levels with defined expectations for scope, quality, and mentorship. Moving up usually requires owning outcomes end to end rather than completing assigned tickets.
