About Project

Dreamlines helps travelers find and book their dream cruise — working with the world's leading cruise lines across Germany, the UK, Australia, and the Netherlands. Our website is a major commercial engine: it connects millions of travellers with high-consideration, high-value offers, and every improvement to search, discovery, landing pages, or enquiry flows has real revenue impact.

We work in a remote-first setup with a 10+ person engineering team based across Germany and Eastern Europe. The culture is practical and delivery-oriented: we value clear thinking, fast iteration, and people who still enjoy doing the detail work.

The Role

We're looking for a hands-on Product Manager to own conversion growth across our website and emerging AI-mediated discovery experiences. This is a role with real ownership: you'll set the CRO roadmap, guide a designer, write requirements, run experiments, and ship improvements that move the numbers.

Beyond the website, you'll help us think ahead — how customers discover cruises through GenAI interfaces, conversational search, and AI assistants is changing fast. You'll be the person who figures out what that means for Dreamlines, and turns that thinking into practical product work.

Why This Role Is Worth Your Attention

• Real ownership from day one — you'll set the CRO roadmap, not just execute someone else's
• High-impact surface: cruise bookings are high-consideration purchases where UX and conversion design genuinely matter
• Genuine AI latitude — use AI tools your way to improve how you think, write, ship, and measure
• A focused, senior team: no bureaucracy, short feedback loops, decisions made quickly
• A product that's evolving fast — GenAI discovery is a real emerging frontier, not a buzzword here

What You'll Do

Conversion & Growth

• Own the CRO roadmap across search/discovery flows, landing pages, offer pages, forms, and enquiry journeys
• Identify, prioritize, and deliver improvements based on data, funnel analysis, and commercial impact
• Define, monitor, and publish conversion metrics so the team always knows what's working
• Plan and evaluate experiments with clear hypotheses, success metrics, and post-launch reviews

Design & UX

• Guide a designer with a clear conversion and usability lens — making design work harder, not just prettier
• Own page layouts, information hierarchy, CTAs, trust signals, mobile experience, and offer presentation
• Use AI to review design briefs, compare UX alternatives, and identify friction before development starts

GenAI Discovery

• Own the product approach for how Dreamlines appears in AI assistants, conversational search, and answer engines
• Define user journeys that connect AI discovery to website conversion, enquiry flows, and qualified leads
• Work with SEO, content, and technical teams to ensure our content is structured for GenAI interpretation

Remote Delivery

• Write clear, complete requirements that reduce ambiguity across time zones
• Maintain a well-prioritized backlog of tickets that are ready for design and development
• Use AI to improve handover quality so remote engineers move faster with fewer questions

Who You Are

• 4–6 years in ecommerce product management, CRO, growth product, or digital optimization
• Track record improving commercial websites where conversion, lead generation, or funnel performance actually mattered
• Comfortable with analytics, dashboards, funnel data, and using experiments to prioritize work
• Strong written communication — you can write requirements a remote developer in a different timezone can build from
• Hands-on, detail-oriented, and delivery-focused — you enjoy the detail work, not just the strategy
• Enthusiastic AI user — you already use AI tools daily and are curious about making them even more central to how you work

Especially Valuable Experience

• Travel, marketplaces, lead generation, comparison sites, or other high-consideration purchase journeys
• Working with remote teams across European time zones
• A/B testing, CRO programs, behavioral analytics, or UX research
• Structured content, answer engine optimization, conversational UX, or AI-assisted discovery

What You Get

• A high-impact role on a platform used by thousands of customers
• No time tracking
• A supportive and experienced engineering team
• Internal learning and development program
• 20 vacation days
• Medical care & wellbeing
• Accounting support
• Office gym with a personal trainer
• Family-friendly space

ChatOn is an AI chatbot assistant app with 100M+ downloads – the #1 product in our portfolio by revenue and downloads. We lead in mobile. Now we’re scaling the web, and we’re looking for a Head of Performance Marketing who’ll own that mission.

This isn’t a role for someone who manages from a distance – we’re inviting an expert who can dive into the data, audit a campaign and provide precise, actionable direction to the team to elevate our execution from good to world-class. You’ll bridge the gap between high-level strategy and tactical excellence, working with multi-million dollar budgets, a full in-house creative machine, and a highly capable team.

Your scope goes beyond UA: you’ll own web growth, mobile acquisition, and ASO from one seat.

Let’s take the web from solid to dominant!

The opportunity for impact here is real – and so is the accountability.

What you will do:

• Own performance marketing end-to-end: define the UA strategy across all channels, set the roadmap, and drive the numbers – ROMI, CAC, LTV, forecast profit – while ensuring strong Web–Mobile synergy
• Be the playing coach the team needs: audit campaigns, read attribution setups, diagnose what’s not converting, and give your colleagues precise direction to fix it. You won’t run campaigns yourself – but you could, and the team will know it
• Build a real experimentation system: translate data into hypotheses, hypotheses into tests, and tests into scaling decisions. Every pivot explainable, every win repeatable
• Defend and evolve the strategy at board level: in your first 90 days, present a full UA strategy – mobile and web – to the board. Quarterly, you own the forecast and the narrative behind it
• Lead and grow the team: UAMs, Web Growth Manager, ASO Manager, and Graphic & Promo Designer. Build a culture where ownership is the norm. Coordinate with the Brand, PR, and Influencer Marketing teams
• Connect marketing signals to product: bring acquisition data, user insights, and market intelligence into product discovery. Help build growth loops that compound over time
• Partner and collaborate closely with the in-house creative team on creative strategy for paid channels

What you should have:

• A proven track record in User Acquisition – you grew up in UA, you know the discipline inside out, and performance marketing is your native language
• 5+ years running paid growth teams with direct accountability for growth metrics – revenue, CAC, ROMI – in B2C subscription products
• Confirmed cases of scaling web acquisition – numbers you can talk through, not just channels you’ve touched
• Channel mastery: Meta, Google, TikTok and beyond. You can walk into any ad account, read what’s wrong, and tell the team exactly how to fix it
• Leadership experience with a team of direct reports – you’ve hired, mentored, and if necessary, made hard calls. You know what a high bar looks like and you hold it

What we offer:

• The #1 app in the portfolio – mature product, proven demand, real budget. We move at scale
• Competitive fixed compensation + generous performance-based bonus. We share the upside when the numbers move
• A full creative machine in-house: motion designers, graphic designers, brand, PR, influencer marketing. You orchestrate – they execute. No agency dependency
• Results-oriented colleagues committed to scaling impactful products. Your team will help you achieve the most ambitious goals
• Remote-friendly work environment with high autonomy and minimal bureaucracy

• Design, develop, and maintain scalable backend services that directly power our gaming products.
• Take ownership of complex backend systems, from technical design to delivery, monitoring, optimisation, and support.
• Continuously improve system performance, latency, reliability, and scalability in a high-throughput environment.
• Collaborate closely with Product Owners, engineers, and cross-functional teams to deliver features end-to-end.
• Drive and participate in code reviews, setting a high standard for clean, maintainable, efficient, and production-ready code.
• Conduct architectural reviews and guide the team toward practical, scalable, and long-term technical solutions.
• Solve complex business and technical problems with a strong engineering mindset and pragmatic decision-making.
• Act as a technical role model for the team by showing strong ownership, discipline, and engineering excellence.
• Mentor other engineers through daily collaboration, technical discussions, and hands-on example.
• Participate in on-call rotations within the squad to ensure system reliability, availability, and fast incident response.
• Grow toward technical leadership while remaining strongly connected to code, delivery, and system ownership.

Requirements

• Strong hands-on backend engineering experience with a proven record of writing production code on a daily basis.
• Solid experience with Node.js and TypeScript is highly preferred. Strong experts in other OOP languages such as Java, Python, C++, C#, or Go may also be considered.
• Strong understanding of asynchronous programming and event-driven architecture.
• Practical experience with distributed systems and messaging technologies such as Apache Kafka and gRPC.
• Experience working with relational databases such as MySQL or PostgreSQL.
• Experience with columnar databases such as ClickHouse and/or NoSQL technologies such as DynamoDB or MongoDB.
• Strong ability to design, build, test, deploy, and maintain production-ready backend services.
• Experience developing and maintaining unit tests, integration tests, and end-to-end tests.
• Proven ability to work with high-load, scalable, and business-critical systems.
• Strong debugging, problem-solving, and performance optimisation skills.
• Ability to make technical decisions independently and take responsibility for their impact.
• Strong code quality mindset, with a clear understanding of maintainability, reliability, and long-term system health.
• Readiness to grow into a technical leadership role while remaining hands-on.
• Degree in Computer Science, Software Engineering, or a related technical field.

Nice to Have
