About Nebius:
Nebius is leading a new era in cloud infrastructure for the global AI economy. We are building a full-stack AI cloud platform that supports developers and enterprises from data and model training through to production deployment, without the cost and complexity of building large in-house AI/ML infrastructure.
Built by engineers, for engineers. From large-scale GPU orchestration to inference optimization, we own the hard problems across compute, storage, networking and applied AI.
Listed on Nasdaq (NBIS) and headquartered in Amsterdam, we have a global footprint with R&D hubs across Europe, the UK, North America and Israel. Our team of 1,500+ includes hundreds of engineers with deep expertise across hardware, software and AI R&D.
The role
We're looking for a
Senior Customer AI Engineer
who will join our
Token Factory
team to help our customers successfully transition from proof-of-concept to production and scale their AI workloads on Nebius infrastructure.
This role sits at the intersection of
engineering, delivery, and customer success
– ensuring that what was promised during pre-sales actually works reliably in production. You will work closely with customer engineering teams, Solution Architects, and Product/Infrastructure teams to drive
stable, performant, and cost-efficient deployments
.
This role is NOT:
A sales role (though you will support expansion through value)
A pure support role (you won’t just react to tickets)
A solution architect role (you won’t design systems from scratch)
You’re welcome in our office in
Tel Aviv, Israel.
Your responsibilities will include:
Own the production journey
• Lead the transition from PoC to production
• Ensure customer workloads are deployed, stable, and scalable
• Drive time-to-production and time-to-value
Ensure technical success in production
• Understand customer architectures and use cases
• Monitor and improve:
o performance (latency, throughput)
o cost efficiency
o reliability
• Identify and resolve bottlenecks proactively
Act as a trusted technical partner
• Work directly with customer engineering teams
• Provide guidance on best practices and optimisation
• Translate technical challenges into actionable solutions
Manage risks and incidents
• Act as a primary technical contact for production issues
• Coordinate with internal teams to resolve incidents
• Communicate clearly during high-pressure situations
Drive continuous improvement
• Identify opportunities to optimise and expand usage
• Provide structured feedback to Product and Infrastructure teams
• Help shape better solutions based on real customer needs
We expect you to have:
Technical background
Practical knowledge of inference frameworks (e.g. vLLM, TensorRT, or similar)
Solid understanding of:
- cloud or infrastructure systems
- distributed systems or high-load applications
- AI/ML workloads (LLMs, inference, etc.)
Ability to troubleshoot and reason about system performance
Customer-facing experience
Experience working directly with technical customers (e.g. engineers, ML teams)
Ability to communicate complex topics clearly and effectively
Ownership & execution
Strong sense of ownership – you drive outcomes, not just tasks
Ability to manage multiple customers and priorities
Structured, proactive, and solution-oriented mindset
It will be an added bonus if you have:
Experience with GPU workloads or AI infrastructure
Background in solutions engineering, SRE, or technical support in B2B environments
Benefits & Perks:
Competitive compensation
Career growth and learning opportunities
Flexibility and ownership
Collaborative and innovative culture
Opportunity to work on impactful AI projects
International environment and talented teams
What's it like to work at Nebius:
Fast moving - Bold thinking - Constant growth - Meaningful impact - Trust and real ownership - Opportunity to shape the future of AI

Social Discovery Group (SDG) is a group of social discovery companies. SDG solves the problems of loneliness, isolation, and disconnection - transforming virtual intimacy into the new normal. SDG’s products redefine the way people interact and connect with one another.
Our portfolio includes social entertainment platforms designed to connect people online across different cultures and regions of the world.
We bring together a team of like-minded people and IT professionals who specialize in creating and developing globally impactful social discovery products. Our international team of digital nomads works remotely from all over the world.
We’re proud to be a two-time “Great Place to Work” winner (USA & Japan, 2024–2025) and a Top-5 Company for Work-From-Anywhere Jobs (FlexJobs, 2025).
We are looking for a Product Owner (Customer Experience).
In this role, you will own the end-to-end customer journey across our products, from the first visit to meaningful long-term connections. Your mission is to find the biggest growth opportunities in a product used by a million-strong audience, remove whatever stands between users and a great experience, and turn every improvement into measurable business results.
Your main tasks will be:
Own the customer journey end-to-end, from registration to quality conversations, identifying friction points and growth opportunities across the whole funnel.
Dig into data yourself: explore analytics with AI tools (e.g., querying BigQuery via MCP), validate insights, and turn them into strong, evidence-backed hypotheses.
Write concise product briefs and drive ideas through specs, prototyping, and release together with developers, analysts, and designers.
Build and prioritize the backlog based on the value each initiative brings to users and the business.
Connect every initiative to business impact (revenue, net profit) rather than isolated conversion gains.
Scale successful experiments across our product portfolio.
We expect from you:
Experience as a Product Owner, Product Manager, Project Manager, or Team Lead in B2C products; startup experience is welcome.
A hands-on approach: you do the analysis, write the briefs, and push ideas through to results yourself.
Practical experience using AI tools for product analytics and documentation.
Strong command of product metrics and funnel analytics, combined with a solid understanding of unit economics.
Track record of owning a business metric (revenue, turnover, net profit), not only conversion rates.
Strong prioritization skills and comfort working with a broad scope.
Persistence and drive to achieve results in challenging conditions.
A technical background (degree in a technical field or previous development experience) is a strong plus.
Why join:
Real influence on the user experience of a product with a million-strong audience.
Freedom to improve anything along the customer journey, from small UX fixes to bold product changes.
A role for people who want challenging problems and a fast path to growth.
What do we offer:
REMOTE OPPORTUNITY to work full-time;
The initial pay level or pay range for this role will be shared with candidates during the recruitment process and before the commencement of employment;
Vacation 28 calendar days per year;
7 wellness days per year (time off) that can be used to deal with household issues, to lie down and recover without taking sick leave;
Bonuses up to $5000 for recommending successful applicants for positions in the company;
50% payment for professional training, international conferences, and meetings;
Corporate discount for English lessons;
Health benefits. According to the paychecks, if you are not eligible for corporate medical insurance, the company will compensate you with up to $1,000 gross per year per employee. This can be spent on self-purchase of health insurance or on doctor’s fees for yourself and close relatives (spouse, children);
Workplace organization. The company provides all employees with an equipped workplace and all the necessary equipment (table, armchair, wifi, etc.) in our offices or co-working locations. In the other locations, the company provides reimbursement of workplace costs up to $1000 gross once every 3 years, according to the paychecks. This money can be spent on the rent of the co-working room, on equipping the working place at home (desk, chair, Internet, etc.) during those 3 years;
Internal gamified gratitude system: receive bonuses from colleagues and exchange them for our merchandise, team building activities, massage certificates, etc.

About the Project
Project Hydrus is a scripted and conversational audio data collection project. The recordings produced help build natural, everyday-sounding synthesized voices for conversational AI products — voices that sound like real people talking, not scripted performances.
As Session Director, you'll lead live recording sessions with Voice Contributors, guiding them through scripted scenarios to produce natural, conversational-quality audio. This hands-on role blends creative direction, coaching, and technical audio judgment — making scripted material sound authentic and unscripted, rather than recited, while keeping sessions moving at a natural pace.
What You'll Do
Direct voice performers through scripted scenarios, coaching for natural, conversational delivery rather than verbatim recitation.
Build quick scene context for performers (who, where, why) and improvise to fill narrative or dialogue gaps live, keeping sessions flowing naturally.
Adapt scripted wording for natural phrasing and regional/dialect authenticity as needed.
Monitor and correct technical audio quality in real time: mic technique, pacing, clarity, and background noise.
Manage session pacing to meet recording targets without sacrificing performance quality, and maintain organized notes on adjustments and retakes.
Create a supportive, low-pressure environment for performers, including those with limited prior voice experience.
What We're Looking For
Required
Native fluency in the required language (with specific dialect), with a strong ear for natural, colloquial phrasing.
Experience directing, coaching, or producing voice or audio talent (e.g., voice direction, casting direction, audio/podcast production, dubbing/ADR, or theater direction).
Demonstrated ability to give clear, specific, actionable performance direction.
Strong working knowledge of basic recording/mic technique (proximity, plosives, room noise, levels).
Comfortable improvising and adjusting scripted material on the spot.
Excellent interpersonal skills; able to build rapport quickly with performers of varying experience levels.
Preferred (nice to have, not required)
Background in improv, theater direction, or acting coaching.
Experience directing non-professional or first-time voice talent specifically.
Familiarity with DAWs or recording software (e.g., Pro Tools, Adobe Audition, Reaper) for spot-checking audio quality.
