Every stage is geared toward verifying that you possess the "architect-level" thinking required to own a tech stack or lead a standardization effort.

This visual timeline highlights the progression from technical screening to final assessment. Use it to gauge the intensity of each stage; earlier rounds will focus on your technical foundation, while later stages will increasingly test your strategic judgment, communication skills, and ability to influence technical direction.

Technical Implementation

• Mastery of the "full stack" is essential. You must show proficiency in both high-level research (e.g., PyTorch for model design) and low-level optimization (e.g., C/C++ for codec prototyping). Strong performance involves demonstrating how you profile performance, manage memory, and translate theoretical models into production-ready code.

• Be ready to go over:
• GPU-accelerated training and inference workflows.
• Performance tuning for latency and throughput.
• Codec prototyping and integration challenges.
• Example: "Walk us through how you would optimize a neural network tool for a specific hardware target."

Standardization & IP Strategy

• This area distinguishes a senior researcher from a standard engineer. You are evaluated on your understanding of the patent process and your track record of contributions to bodies like JVET or MPEG. Success here means showing you can balance technical gain with patentability.

• Be ready to go over:
• The lifecycle of a standards proposal.
• Aligning test conditions and baselines with industry partners.
• Documenting inventions for the patent filing process.
• Example: "How do you ensure your research results are robust enough to be accepted as a standard contribution?"

Architecture & Technical Direction

• You are being hired as a technical owner. Interviewers want to see that you can set the research roadmap, remove blockers for your team, and make high-level design decisions that have cross-team impact.

• Be ready to go over:
• Defining research framing for long-term projects.
• Mentoring and code review best practices.
• Navigating technical disagreements with cross-functional teams.
• Example: "Describe a time you had to pivot your research direction based on new findings; how did you communicate this to stakeholders?"

As a Research Engineer, your primary objective is to drive technical breakthroughs that translate into standardized solutions and intellectual property. You will own the technical direction for specific components of the company's research portfolio, such as neural network-based video coding or advanced communication protocols.

Your day-to-day work involves a blend of hands-on research and high-level collaboration. You will be responsible for:

• Designing, training, and evaluating complex models using frameworks like PyTorch.
• Implementing and profiling these models in C/C++ to ensure they meet the rigorous latency and throughput requirements of modern codecs.
• Authoring technical proposals and defending them within international standards bodies.
• Collaborating with patent attorneys to translate your research innovations into filed patents.
• Providing technical coaching and code reviews to elevate the output of the entire R&D team.

A successful candidate for a Research Engineer position at Ofinno must demonstrate a unique blend of academic depth and practical engineering skill.

• Must-have skills:
