The Role
We are looking for a Full-Stack Developer to join a team building and maintaining a large-scale mobile security platform. This role combines software development with hands-on investigation of complex technical issues in enterprise environments. You will work primarily with backend systems while contributing to application development, troubleshooting production problems, and delivering fixes that improve product reliability. Working closely with customers and internal Support, Product, QA, and Engineering teams, you will turn real-world technical findings into practical solutions and help improve the product's quality and performance.
About the Product
The Mobile Security product combines protection running on mobile devices with backend services that support centralized security policy management, integrations, and data processing. Its infrastructure supports multiple products and enterprise environments, requiring high standards of security, performance, scalability, and reliability. The development team works on both the backend capabilities and the technical challenges that arise when the platform operates in real-world customer environments.
Technology Stack:
The backend relies on Java, Node.js, and TypeScript, delivering scalable microservices and APIs over Unix environments. The frontend is built on React, providing a modular architecture for enterprise management interfaces. Everything is version-controlled via Git and deployed through automated CI/CD pipelines, supported by comprehensive log analysis and performance profiling tools to maintain strict system health.
What You’ll Be Doing
- Own the technical investigation and resolution of complex production challenges in large-scale backend environments
- Modify and enhance large-scale codebase features across Java, Node.js, TypeScript, and React architectures
- Direct enterprise issue resolution by translating real-world customer findings into long-term product and system fixes
- Optimize API interactions, data processing routines, and server-side performance across distributed architectures
- Collaborate with global Support, QA, Product, and Engineering teams to refine the endpoint security product roadmap
- Utilize advanced debugging, log analysis, and profiling tools to execute root-cause investigations under tight operational constraints
What We Expect
Desired Background
- A degree in Computer Science, Engineering, or equivalent training in software development
- 1–2 years of experience with Java, Node.js, TypeScript, and React, including the ability to navigate and modify a large-scale codebase
- Experience working with Unix environments and Bash
- Strong understanding of server-side systems, distributed architectures, APIs, and database interactions
- Hands-on experience with debugging tools, log analysis, performance profiling, and root-cause investigation
- Familiarity with endpoint security concepts, network security fundamentals, and enterprise IT environments
- Experience with CI/CD pipelines, version control using Git, and Agile development practices
Desired Personal Qualities
- Strong written and spoken English communication skills
- Excellent problem-solving skills and a methodical, analytical approach to investigating complex technical issues
- Ability to explain technical details clearly to customers and internal teams
- A customer-focused mindset, with a strong sense of ownership and urgency when resolving issues affecting production environments
- Ability to move effectively between quick bug fixes and longer, in-depth technical investigations
- A collaborative approach to working with Support, QA, Product, and Engineering teams, while maintaining professionalism under pressure
Why This Role Is Worth Your Time
- Contribute to security technology used by organizations around the world
- Combine hands-on software engineering with challenging investigations into real production issues
- Gain exposure to large-scale backend infrastructure, enterprise environments, and practical cybersecurity challenges
- Work closely with international teams across Engineering, Product, QA, and Support
- Help improve product reliability and influence technical decisions by turning complex problems into lasting solutions
