Jobs at Djinni

We are looking for a skilled Senior Technical Product Manager who can bridge product, engineering, AI quality, UX, and commercial decision-making.

Client: VC-funded AI tourism platform building the next generation of travel experiences through artificial intelligence.

Product: The product ecosystem includes an AI travel assistant, content enrichment systems, and partner integrations that help transform how travelers discover, plan, and experience destinations.

Team: Small, highly technical team that moves quickly, ships frequently, and focuses relentlessly on product quality and customer value.

Technology stack:

• AI products: an AI travel assistant and a content enrichment system
• Backend: Go monorepo, 3+ services
• Hosting: PaaS-managed containers
• Observability: Jaeger tracing, Betterstack
• Databases: PostgreSQL, Redis
• AI tooling: Claude Code used across the team

The Role

This is a supportive Senior Product role, not a Head of Product or Pod Lead. You will act as a Product Manager supporting two or three engineering pods, helping improve product quality, user experience, AI performance, commercial viability, and market competitiveness.

You must be technically experienced enough to discuss prompts, evaluations, model behavior, and architecture with engineers as peers and be willing to build small things on your own.

What you’ll actually do:

• Sit alongside two to three engineering pods as their senior product partner, advising on quality, roadmap, and behavior while pod leads own delivery
• Run market and competitor analysis across AI travel, AI assistants, and supplier platforms, and feed that back into the roadmap and pricing decisions
• Own the commercial and pricing input on client deals, working with the founders so that contracts and scope reflect what we actually build
• Lead UX research and design oversight across products, raising the bar on internal tooling and customer-facing interfaces
• Translate user behavior, supplier feedback, and competitor moves into clear, testable improvements
• Review AI assistant prompts and interactions regularly, working with engineers on evals and quality benchmarks
• Build dashboards and reporting that turn AI performance into a story stakeholders can read
• Join client and supplier calls when product context, pricing, or commercial discussions are on the table

What you will contribute to:

• Market and competitor intelligence across AI travel and assistant products
• Commercial input on pricing, contracting, and client scope
• UX research and design quality across our AI products and partner-facing surfaces
• Eval coverage, quality dashboards, and AI performance reporting
• Product context for supplier and client integrations

You are a great fit if you:

• Get genuinely curious when an AI product behaves unexpectedly and dig in until you understand why
• Think in user journeys, quality metrics, and commercial impact rather than tickets and burndowns
• Are comfortable being a senior advisor across multiple pods rather than running one of them
• Care more about whether the product works for real customers than about the process ceremony
• Enjoy working in a small, fast team where your decisions reach users quickly
• Want to stay long-term and help shape how AI changes travel

🙅 Probably not the right role for you if:

• Your background is mainly project management, Scrum mastery, or engineering management
• You have never worked on a product that uses LLMs in production
• You have never owned commercial or pricing responsibility
• You expect to lead a pod or have engineers report to you
• You expect detailed specs handed to you before you start
• You are outside European or African time zones

Required ExperienceMust Have

• Critical: Hands-on engineering background before moving into product management. If you have only worked as a Project Manager or Scrum Master, this role is not for you
• Production software development experience within the last 5 years
• Critical: Recent active use of Claude Code or an equivalent agentic tool within the last 12 months, and willingness to still build small things hands-on
• Critical: 3+ years co-leading or leading product at an enterprise B2B or SaaS company, with both commercial and product responsibilities
• Critical: Hands-on experience with AI products in production. Deep understanding of: prompts, evals, harnesses, hallucination handling, and model selection
• Strong technical experience: you can read code, follow an architecture diagram, and push back on engineers without overriding them
• Experience with internal admin tooling and B2B user interfaces, not only consumer products
• Excellent written and spoken English
• Availability to work full-time within ±3 hours of CET

Nice to Have

• Travel industry experience
• German language skills
• Past work on AI assistants, chat-based products, or recommender systems
• Corporate or legacy enterprise background alongside startup experience
• Experience setting up product analytics, evaluation frameworks, and quality dashboards from scratch

Job Details:

• Full-time, 40hrs/week
• Fully remote work
• Long-term cooperation
• Modern AI-first development environment (heavy use of Claude Code)
• International team
• Paid sick leave, vacation days, and benefits
• B2B contract

About the Project
We are looking for a Senior Data Scientist / ML Engineer to support a Berlin-based logistics technology product company on a data science project focused on building a production-ready MVP.
The project is currently in an early research / proof-of-concept stage. Initial validation has shown that the concept is technically feasible, and the next step is to bring it from research into a usable MVP that can be integrated into the existing product infrastructure.
The solution will use positional / location-based data to identify specific locations and generate insights that help drivers and improve operational efficiency.
This is not a fully isolated greenfield project. The work will be connected to existing internal systems, data pipelines, and infrastructure. Therefore, the ideal candidate should be highly autonomous, senior enough to clarify requirements directly with internal stakeholders, and able to take ownership of the solution with limited day-to-day supervision.

Responsibilities

• Own the data science and ML development work from research validation to a usable MVP.
• Build and improve data pipelines and ETL processes that feed the model.
• Work with positional / geospatial / location-based data.
• Develop, validate, and iterate on ML models that identify relevant locations and generate useful outputs for the product.
• Prepare the model and pipelines to run in production on a scheduled basis.
• Work with internal data, product, and engineering teams to understand available data, infrastructure, constraints, and business requirements.
• Translate high-level product and business goals into technical implementation steps.
• Make technical decisions independently while keeping internal stakeholders aligned.
• Document the solution, assumptions, limitations, and handover materials for the internal team.
• Ensure that the MVP can be further scaled, improved, and integrated into the company’s existing product suite.

Required Experience

• 5+ years of experience in Data Science, Machine Learning, or ML Engineering.
• Strong hands-on experience building ML models from concept to production or MVP stage.
• Experience working with ETL processes, data pipelines, data preparation, and model input pipelines.
• Strong Python experience and common data science / ML libraries.
• Experience working with large datasets and imperfect real-world data.
• Ability to work with positional, geospatial, mobility, logistics, or location-based data.
• Experience deploying or preparing ML models for production usage.
• Strong understanding of model evaluation, iteration, and practical trade-offs between accuracy, speed, and business value.
• Ability to work independently with limited day-to-day guidance.
• Strong ownership mindset: ability to clarify requirements, identify blockers, communicate with stakeholders, and drive the work forward.

Nice to Have

• Experience in logistics, transportation, mobility, route optimization, delivery, or fleet-related products.
• Experience with cloud data infrastructure such as AWS, GCP, or similar.
• Experience with scheduled production pipelines, batch processing, or workflow orchestration tools.
• Experience handing over ML solutions to internal engineering or data teams.
• Previous experience in startup or product-company environments.

We’re proud to be ranked 4th among the World’s Top EdTech Сompanies by TIME magazine. We believe lifelong learning should be accessible, personalized, and impactful to each individual. That’s how we change the world and why we bring together exceptional minds.
 

The core of our achievements is our team. We believe in people and shared values SELECT. That’s why, together with Mariana Boloban, Head of People, we’re looking for a Head of HR to build and scale a consistent, high-quality HR function across the company.
 

The team you will be working with:

You’ll work with the HR team in close partnership with People Operations — a team focused on enabling business goals through manager development, stronger cross-team collaboration, and building a mature people management system. We support stable performance, high engagement, and a strong employee experience.
 

As a Head of HR, you will:

• Directly influence business performance by shaping how teams are structured, how goals are set, and how people are managed.
• Turn business challenges into clear people decisions — helping leaders move faster, with less ambiguity and stronger accountability.
• Lead and develop a team of HR Specialists, supporting them in complex people cases and growing their functional maturity.

Your mission:

Partnering with the HR team and the broader People Operations function, you will build a people system where strong teams consistently deliver business results.
 

This job is perfect for you if you:

• Want to directly impact business results through people
• Are excited to work with a strong company culture and further develop it as a management tool that drives performance, accountability, and team effectiveness.
• Thrive in fast-paced environments where priorities shift, decisions matter, and you have the flexibility and ownership to drive meaningful changes
• Want to grow and develop an HR function and team, making it stronger, more independent, and more impactful over time.
   

What will you do:

• Own the quality and consistency of HR decisions across the company, ensuring they are fair, scalable, and aligned with business goals.
• Build and scale HR as a system — from performance management and PDP to career development, lifecycle standards, and decision-making frameworks.
• Align managers across teams and tribes, creating shared expectations around performance, feedback, and people decisions.
• Turn people data into actions, using engagement, retention, and performance signals to identify risks and drive improvements.
• Develop the HR function and team, building strong HR Specialists, clear competency frameworks, and increasing overall functional maturity.
• Partner with People Operations leaders (TA, People Infrastructure, Head of People) to ensure aligned, non-conflicting people decisions at scale.
   

What do you need to join us:

• 4+ years in a Lead / Head of HR role in fast-growing product or tech companies, with ownership of business-critical people decisions.
• Proven experience driving business outcomes through HR — impacting performance, retention, and team effectiveness, not just processes.
• Strong experience building and scaling HR systems (performance, career development, lifecycle, governance), not only operating them.
• Experience working with multiple teams or org units (100+ people) and aligning different leaders into a consistent approach.
• Strong business acumen and leadership skills — able to challenge leaders, navigate ambiguity, and make tough decisions that impact delivery.
• English — Upper Intermediate+.
• Alignment with the values of our team (SELECT).
   

What do we offer:

• Work within an ambitious team on a socially impactful education product.
• An office with a reliable shelter, generators, satellite internet, and other amenities.
• Access to our corporate knowledge base and professional communities.
• Personal development plan.
• Compensation for English language learning, external training, and courses.
• Medical insurance and full sick leave compensation.
• Company doctor and massage in the office.
• Sports activities: running, yoga, boxing, and more.
• Corporate holidays: we go on a week-paid holiday to rest and recharge twice a year.
• Supporting initiatives that help Ukraine.
   

Working schedule:

This is a full-time position based in Kyiv with a hybrid setup. We stay flexible, but for this role our focus is on working from the office most of the time — it helps to stay close to context, and most of the team are based in Kyiv.
