We are currently hiring

Staff Engineers for two TuxCare products: KernelCare and SecureChain .

KernelCare KernelCare

provides automated live patching for Linux kernels without requiring reboots, helping organizations keep production systems secure while avoiding operational downtime.

As a mature and business-critical product, KernelCare offers the opportunity to solve complex engineering challenges at scale, evolve established systems, and improve automation while maintaining a strong focus on reliability and stability.

SecureChain SecureChain

is one of TuxCare's newer security products focused on open-source software supply chain security.

SecureChain helps organizations use open-source dependencies more safely by providing packages rebuilt from verified source code, scanned for malware and supply chain risks, and continuously patched as new vulnerabilities are discovered.

As part of the SecureChain team, you will help build the next generation of automation and high-reliability systems behind these processes, evaluating and improving existing workflows and using AI where appropriate to analyze data, support decisions, and improve operational visibility.

Because SecureChain is still a relatively new product, engineers have significant opportunities to build systems from the ground up and influence its technical direction.

About The Role The role combines deep technical execution with technical product ownership and is approximately

70% hands-on software engineering and 30% technical product ownership .

You will lead significant product components and workstreams end-to-end: clarifying requirements with stakeholders, defining milestones, designing solutions, contributing production code, delivering functionality to customers,



and ensuring its continued reliability in production.

This is an individual contributor role, not a people-management position.

We are looking for someone who can operate autonomously, navigate ambiguity, and drive complex initiatives forward without relying on a manager to define every next step.

As the product and priorities evolve, curiosity, adaptability, and a broad interest in the cybersecurity area will be important for success in this role.

What you'll do:

Own major product components and workstreams throughout their full lifecycle, from initial discovery and planning to production release and ongoing improvement

Work directly with engineering, product, sales, and other stakeholders to understand, gather, and clarify business and technical requirements

Translate broad product goals into technical plans, milestones, and actionable engineering tasks

Design scalable system architecture and make technical decisions for high-impact product areas

Build, review, and maintain production-grade components end-to-end, ensuring reliability, security, performance, maintainability, and extensibility

Take responsibility for delivered components in production and their continued operation and evolution

Independently track progress and proactively communicate results, blockers, risks, dependencies, and changing requirements

Research relevant technologies, tools, market approaches, and competitor solutions when needed

Contribute to engineering quality through design reviews, technical guidance, mentorship, and best practices

Use AI-assisted development tools as part of the regular engineering workflow for planning, implementation, debugging, testing, refactoring, automation, and code review

Requirements

Proven experience owning major projects, products, systems, or workstreams end-to-end

Strong hands-on Python development experience

Strong hands-on Linux experience and confidence working with Linux-based production environments

Strong system design and architectural thinking,



combined with the ability to implement proposed solutions hands-on

Demonstrated experience building substantial systems or features and taking them through production release

Experience gathering and refining requirements and turning broad needs into technical plans, milestones, and deliverables

Strong technical product ownership and an understanding of how engineering decisions support broader product and business goals

Ability to work independently without close day-to-day supervision

Strong communication skills and confidence working directly with engineering teams and cross-functional stakeholders

Ability to clearly explain technical decisions, trade-offs, progress, risks, dependencies, and blockers

Regular use of AI-assisted development tools for planning, implementation, debugging, testing, refactoring, automation, or code review. AI should be part of the development workflow rather than used only for occasional experimentation

Ability to balance short-term delivery with long-term scalability, reliability, maintainability, and extensibility

Curiosity, adaptability, and an interest in cybersecurity and complex technical problems

Advanced written and spoken English

Nice to have:

Experience working with CVEs, vulnerability management, or security-related engineering workflows

Understanding of commercial processes and how technical decisions can support product and business objectives

Benefits What's in it for you?

Stay hands-on technically while owning complex, high-impact engineering work

Work on challenging Linux, automation, and cybersecurity problems across mature and newer products

Influence technical direction and make meaningful architectural decisions

Work independently with a high level of ownership and autonomy

Fully remote work with versátil working hours

24 paid vacation days, 10 national holidays, and unlimited sick leave

Private medical insurance compensation

Co-working and gym/sports reimbursement

Education budget

Opportunity to receive a reward for innovative ideas that the company can patent
