What is a software engineer startup?

A Software Engineer Startup job involves developing, testing, and maintaining software in a fast-paced, early-stage company. Engineers in startups often wear multiple hats, working on both backend and frontend development, infrastructure, and sometimes even product decisions. The role requires adaptability, problem-solving skills, and the ability to work with limited resources. Unlike larger companies, startup engineers may need to prototype quickly, iterate based on user feedback, and contribute to the overall growth strategy. This position is ideal for those who enjoy dynamic environments and taking ownership of projects.

What are the key skills and qualifications needed to thrive in the software engineer startup position, and why are they important?

To thrive as a Software Engineer in a startup environment, you need solid programming skills, a problem-solving mindset, and a degree in computer science or related experience. Familiarity with agile methodologies, cloud platforms, version control (like Git), and rapid prototyping tools is highly valued, and startup engineers may also benefit from exposure to full-stack development. Adaptability, effective communication, and the ability to work independently in uncertain environments are standout soft skills. These competencies enable engineers to rapidly iterate on products, effectively collaborate across small teams, and contribute to the dynamic demands of a growing company.

What can I expect from the daily work environment as a software engineer at a startup?

Working as a Software Engineer at a startup typically means you'll be part of a small, agile team where roles and responsibilities can shift quickly based on company needs. You'll often participate in daily stand-ups, collaborate closely with founders or product leads, and have the opportunity to contribute ideas beyond your core coding tasks. The pace is usually fast, and you'll likely wear multiple hats, working on everything from prototyping new features to troubleshooting production issues. This hands-on, collaborative atmosphere provides excellent opportunities for skill growth, creative problem-solving, and making a visible impact on the company's direction.

Job description

Senior Software Engineer / Software Developer (React Native) 

Build what's next for players.

We're a startup inside Sony PlayStation. Fast-moving, experimental, and highly ambitious. Backed by the scale, resources, and trust of Sony Interactive Entertainment. We're building new mobile and web experiences that help gamers connect, discover, and play together in better ways. This is a rare opportunity to design at startup speed and drive huge impact inside the largest gaming company in the world.

We are seeking a Senior Software Engineer / Software Developer specializing in React Native and high-performance frontend development for mobile platforms. In this role, you will define the architecture, frameworks, and technical best practices.

You will collaborate closely with engineers, product, and design teams to deliver best-in-class user interfaces that are performant, accessible, and delightful at scale. As a Senior Engineer, you will provide technical leadership across teams, mentor engineers, and push the boundaries of what's possible in cross-platform frontend development.

Responsibilities

  • Define and evolve the frontend architecture for client applications on mobile using React Native and modern JavaScript/TypeScript.
  • Drive performance optimizations and best practices for rendering, startup time, and UI responsiveness.
  • Design and integrate custom native modules (Native Android or Native iOS) and optimize cross-platform interoperability.
  • Partner with product managers, designers, and researchers to translate user experience requirements into elegant, maintainable solutions.
  • Establish coding standards, testing strategies, and development patterns that raise the quality bar for frontend engineering.
  • Mentor engineers and act as a multiplier for frontend development expertise across the broader team.
  • Investigate new frontend technologies, frameworks, and performance techniques, and guide their adoption when appropriate.
  • Represent frontend/OS needs in technical and architectural discussions.

Requirements

  • 5+ years of software development experience, with significant experience building React Native apps or high-performance JavaScript/TypeScript applications.
  • BS/MS degree in Computer Science or equivalent.
  • Expertise in native Android development (Kotlin/Java/Gradle) and shipping applications to the Google Play Store.
  • Strong expertise in frontend performance profiling, optimization, and debugging.
  • Passion for delivering world-class user interfaces with exceptional performance.
  • Deep understanding of cross-platform architecture and how to bridge between JS and native modules.
  • Proven track record of delivering production-quality mobile or desktop applications with React Native.
  • Experience designing scalable frontend architectures and reusable UI frameworks.
  • Strong collaboration skills and ability to work closely with native engineers, designers, and product managers.
  • Demonstrated technical leadership: leading projects, mentoring engineers, or setting engineering strategy.

Bonus

  • A track record of building social, community, gaming, or other consumer products.
  • Familiarity with VoIP, call dialing and ringing flows in Android/React Native
  • Experience with accessibility, internationalization, and UI testing frameworks. 
  • Familiarity with CI/CD pipelines and modern build systems for frontend development.
  • Previous experience at an early-stage startup or on a zero-to-one product team.
