• Commission and oversee external R&D at partners (universities, research institutes, state bodies, individual experts) within agreed security and access boundaries.
• Run a single intake process for research requests from projects, covering context, goals, deadlines, metrics, input data, and expected artifacts. Return incomplete requests for clarification. Prioritize requests together with Delivery Managers (DM), escalate priority conflicts to HCEE, and keep both informed on scope, timelines, risks, and status.
• Assign a research group and a group lead to each initiative and agree on team composition, timeframe, and expected artifacts. Track progress, risks, blockers, and changes to hypotheses and experiment plans. Prevent scope creep.
• Set and enforce research methodology standards: hypothesis-driven experimentation, evidence requirements (tests, benchmarks, measurements, PoC), peer review before handover, and reproducibility with versioned code and data.
• Ensure availability and quality of research data: datasets, labeling, metadata, registries, versioning, and access policies. Align infrastructure needs with HCEE, including compute, tools, licenses, test benches, and measurement instruments.
• Deliver research results packaged for productization: documentation, interfaces, tests and benchmarks, and integration notes. Coordinate handover to project teams through DM, project managers, and tech leads, and provide implementation support within an agreed period.
• Organize, together with HCEE and DM, testing and adoption of research results in products, including collection of field data and feedback. Based on the results, close the research effort or launch the next iteration.
• Deliver rapid PoCs and risk assessments for pre-sale and critical decisions. Form a research task force when a release or demo is blocked, with priority agreed with DM.
• Maintain the research knowledge base: what was done, what was proven, and how to reproduce it. Initiate internal and external publications where they benefit the company. Coordinate white papers and patent applications, with review by domain SMEs and HCEE approval before external release.
• Act as deputy to the Head of Engineering Excellence Center for applied research. Own research and its transfer into products, while delivery management and system ownership remain with project teams.

Benefits:

• Employment in a stable and reliable company;
• Working remotely, but available to visit office in Kyiv once a month;
• Competitive salary;
• A 5-day work week with an 8-hour workday within the 9:00–20:00 time window;
