At Tiber Technologies, a Software Engineer does not simply build standard commercial applications. You will work on highly specialized, mission-critical engineering challenges that sit at the intersection of national security, cybersecurity, and advanced infrastructure. Whether you are developing low-level Computer Network Operations (CNO) capabilities, reverse engineering complex binaries, or designing scalable cloud and artificial intelligence (AI) infrastructure, your work directly impacts national defense and intelligence operations.

The engineering culture at Tiber Technologies is defined by technical rigor and a deep focus on systems-level programming. Because many of our positions—such as CNO Software Engineer, Embedded Developer, and Cloud Software Engineer—support specialized defense and intelligence contracts, our engineers frequently design tools that operate under strict hardware, memory, and network constraints. You will contribute to projects that require a granular understanding of operating system internals, network protocols, and hardware architectures.

This role is ideal for engineers who thrive on solving highly ambiguous, low-level puzzles and who want their code to serve a vital, real-world mission. You will collaborate with elite teams of security researchers, systems engineers, and cloud architects to deliver robust, high-performance software that cannot afford to fail.

The interview process at Tiber Technologies is designed to evaluate your practical engineering skills, systems-level knowledge, and problem-solving methodologies. The questions below represent the core technical and architectural concepts frequently assessed during our technical evaluations.

Low-Level & Systems Programming

This category evaluates your understanding of memory management, operating system internals, and how software interacts directly with hardware.

Preparing for an interview at Tiber Technologies requires a balanced approach of deep technical review, system-level visualization, and alignment with our mission-focused culture. You should approach your preparation not as an academic exercise, but as a demonstration of your practical, hands-on engineering capabilities.

Systems-Level Mastery – We expect our engineers to understand what happens to their code after it is compiled. You should review operating system fundamentals, memory layouts, and CPU architecture. Be ready to explain how your code interacts with the underlying hardware and OS kernel.

Methodical Problem-Solving – When faced with complex technical scenarios, your process is just as important as your final answer. We evaluate how you break down ambiguous problems, isolate variables, and systematically debug issues. Communicate your thought process clearly and state your assumptions out loud.

Security and Robustness Mindset – Security is not an afterthought at Tiber Technologies. Whether you are writing an embedded driver or a cloud-based API, you must demonstrate an awareness of common vulnerability patterns, secure coding practices, and defensive software design.

Mission and Culture Alignment – Our teams work on projects of national importance. We look for engineers who are highly collaborative, possess strong professional integrity, and are deeply motivated by the unique challenges of the defense and intelligence sectors.

The interview process at Tiber Technologies is highly technical, rigorous, and tailored to the specific domain of the role you are applying for. Because we hire across specialized areas like low-level systems, reverse engineering, and cloud infrastructure, your interview loop will reflect the day-to-day realities of your target team. The process is designed to assess your technical depth, problem-solving speed, and cultural fit.

You can expect a structured progression that begins with an initial conversation and moves into deep technical evaluations. We aim to make the candidate experience transparent and collaborative, giving you the opportunity to meet with the engineers and technical leaders you will be working alongside.

The timeline shown above outlines the standard stages of our candidate evaluation. The initial technical screening focuses on core engineering fundamentals, while the specialized deep-dive rounds assess your specific domain expertise, such as assembly analysis, network protocols, or cloud architecture. Candidates should use this timeline to pace their preparation, ensuring they dedicate sufficient time to practicing low-level concepts and system design before the intensive technical rounds.

To excel in the Tiber Technologies interview process, you must understand the specific core competencies our engineering teams evaluate. Depending on the exact role—whether it is embedded, cloud, or reverse-engineering focused—you will be tested heavily in one or more of the following areas.

Systems Programming & OS Internals

This area evaluates your ability to write efficient, low-level code and your understanding of how modern operating systems manage resources. This is particularly critical for CNO Software Engineers and Embedded Developers.

Be ready to go over:

• Memory Management – Virtual memory, page tables, heap allocation algorithms, and memory-mapped I/O.

• Process & Thread Management – Concurrency, synchronization primitives (mutexes, semaphores), context switching, and inter-process communication (IPC).

• Kernel Space vs. User Space – System calls, driver development, and how operating systems enforce privilege separation.

• Advanced concepts (less common) – Kernel-level debugging, custom memory allocators, interrupt handling, and writing code for real-time operating systems (RTOS).

Example scenarios:

• "Design a thread-safe circular buffer in C without using standard library synchronization primitives."
• "Explain how you would write a custom allocator to prevent memory fragmentation in a resource-constrained embedded system."

Reverse Engineering & Binary Analysis

For CNO Reverse Engineers and Firmware Developers, this evaluation area tests your ability to dissect compiled software, identify program logic, and locate vulnerabilities.
