One of TuxCare’s key products is Endless Lifecycle Support (ELS), which enables organizations to securely continue using Linux distributions and software languages that have reached end of life or no longer receive standard security updates. ELS delivers vulnerability patches for unsupported versions of CentOS, Ubuntu, Debian, Oracle Linux, as well as for runtimes and frameworks such as PHP, Python, Spring, Angular/AngularJS, Django, and Flask.

To drive the further development of ELS and other cross-cutting systems, we are seeking a hands-on Staff Engineer who can combine deep technical execution with product ownership. This role is ideal for someone who operates as a Senior Developer (70%) and a Technical Product Owner (30%). The engineer will work closely with stakeholders to understand their needs, translate them into proof-of-concepts, and evolve those into robust, production-grade solutions. The role requires strategic thinking, strong stakeholder engagement, and the ability to actively shape the product vision and roadmap.

What you'll do:

• Gather requirements from multiple stakeholders on a project
• Lead architectural design and technical direction for high-impact initiatives
• Assist multiple engineering teams in the adoption of scalable, maintainable solutions
• Collaborate across teams to gather requirements and align on priorities
• Promote engineering excellence through design reviews, mentorship, and best practices
• Continuously explore and evaluate new technologies, methodologies, and tools
• Ensure that all solutions are robust, secure, and performant in production environments
• Champion a culture of automation, reliability, and continuous improvement

Real-world Challenge: Building a Unified Dependency Graph
One of our core goals is to map the software supply chain for thousands of applications. You will lead the design of a system that ingests projects and calculates their full dependency trees.

The Complexity:

• Variable Definitions: "Dependency" means something different in every language. We have to handle static vs. dynamic linking, compile-time vs. runtime scopes, and version ranges (e.g., ^1.2.0).
• Context Awareness: The system must understand that dependencies often change based on the environment (e.g., specific libraries for GPU support or Windows).
• Tool Variance: The system must mimic the logic of various package managers (Pip, Poetry, Maven, Gradle) to ensure accuracy.

The Staff Engineer's Mission:

• Research & Strategy: Analyze how 5+ languages handle packages and design a universal data model to store them efficiently.
• Algorithm Design: Create logic to automatically resolve complex dependency trees at scale.
• Consensus: Work with multiple teams to implement this standard across the company.

What we expect from you:

• Programming Languages: Proficiency in Python is a must. Knowledge of any other programming languages is a plus.
• Advanced AI usage: Regular use of LLM-based tools for development, debugging, testing, refactoring, or code review. Not just occasional experimentation.
• Hands-on Engineering Leadership: Requires a senior-level engineer proficient in designing, implementing, and maintaining scalable software systems. Regular code contributions and leading by example in both architecture and implementation are expected
• Technical Product Ownership: Involves shaping product direction — gathering and refining requirements, translating them into technical goals, and aligning them with broader engineering strategies. Experience in technical product management or direct ownership of product roadmaps is highly valued
• Full Lifecycle Responsibility: Encompasses ownership of the entire lifecycle of major components, from initial concept through prototyping, delivery, and ongoing evolution. A balance between short-term iteration and long-term scalability and extensibility is essential
• Cross-Functional Collaboration: Demands active communication with engineering teams, product managers, and stakeholders across departments. Requires the ability to align different viewpoints, prioritize effectively, and turn feedback into actionable plans
• Strategic Thinking + Execution: While the primary focus remains on building, it's important to step back, understand broader product and organizational goals, and make informed engineering trade-offs within that context

What's in it for you?

• A focus on professional development.
• Interesting and challenging projects.
• Fully remote work with flexible working hours, that allows you to schedule your day and work from any location worldwide.
• Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves.
• Compensation for private medical insurance.
• Co-working and gym/sports reimbursement.
• Budget for education.
• The opportunity to receive a reward for the most innovative idea that the company can patent.
