Investigate and resolve complex systems-level issues involving performance, scalability, networking, and software reliability.
Collaborate with engineering colleagues and technical leadership to define architectural decisions, evaluate new technologies, and deliver robust engineering solutions.
Contribute to proprietary and open-source projects, applying sound software engineering practices and maintaining high standards of code quality.
Work with technologies across the broader infrastructure stack, including Go, RabbitMQ, PostgreSQL, ClickHouse, Kubernetes, and GitLab CI/CD.
Participate actively in technical discussions, challenge existing assumptions constructively, and continuously improve engineering practices within a distributed team.

Requirements:

At least 10 years of professional C/C++ software development experience, supported by a strong track record of delivering and maintaining long-term projects across multiple organizations.
Deep expertise in low-level programming, systems development, and network programming, with the ability to solve complex technical challenges close to the infrastructure layer.
Practical experience with web security concepts, including an understanding of web infrastructure, common threats, and approaches to protecting applications and services.
Experience working with SQL and relational database technologies, including the ability to query, manage, and integrate data effectively.
Strong software engineering fundamentals, including debugging, performance optimization, system design, testing, and maintainable code development.
Familiarity with web server architecture and experience developing integrations or extending existing libraries and tools would be highly valuable.
Working knowledge of Go is a strong advantage, particularly for engineers comfortable working across multiple programming languages.
Familiarity with PHP, XML, HTML, and CSS would be beneficial for contributing to web-related components and integrations.
Exposure to technologies such as RabbitMQ, PostgreSQL, ClickHouse, Kubernetes, and GitLab CI/CD is an advantage.
Strong analytical and problem-solving skills, with the ability to design scalable, reliable solutions for demanding technical environments.
A proactive, curious, and growth-oriented mindset, with a genuine interest in learning new technologies and continuously improving engineering practices.
Excellent time management and asynchronous communication skills, with the ability to work independently and collaborate effectively within a remote-first organization.
Strong ownership and accountability, combined with the confidence to question established approaches and contribute constructively to technical decisions.
Previous experience in a startup or high-growth technology environment is a plus.

Benefits:

Fully remote work: Work remotely from within Europe, with flexible working arrangements designed for a distributed engineering team.
Flexible engagement options: Employment contracts are available in Germany, the UK, Spain, and Estonia, with freelance or contractor arrangements available in other European locations.
Competitive compensation: Paid employment with compensation determined by experience, technical expertise, location, and engagement arrangement.
Meaningful technical impact: Contribute to security infrastructure that protects millions of websites and applications worldwide.
Modern technology stack: Work with technologies including C++, Go, PHP, RabbitMQ, PostgreSQL, ClickHouse, Kubernetes, and GitLab CI/CD.
Engineering ownership: Take responsibility across the full development lifecycle and help shape the architecture and direction of critical security products.
Limited legacy constraints: Focus primarily on building new capabilities and solving meaningful engineering problems rather than maintaining heavily outdated systems.
Collaborative technical culture: Work alongside engineers who value curiosity, independent thinking, knowledge sharing, and constructive challenges to established assumptions.
Continuous learning: Expand your expertise in systems programming, networking, web security, and large-scale infrastructure.
Inclusive workplace: Join a team that values diverse backgrounds, perspectives, and experiences and encourages qualified candidates to apply.
