Jobs

Ever worked in an environment where engineers are expected to challenge bad code instead of silently accepting it?
Where spotting hidden bugs, architectural problems, and security risks matters more than shipping features fast?
Where your opinion is valued specifically because you can say: “this implementation is wrong and here’s why”?

If you’re confident reviewing unfamiliar systems, care deeply about engineering quality, and prefer direct technical communication over corporate politeness - this role is for you.

About the Role

At Dreamlines, we help travelers find and book their dream cruise — working with the world's leading cruise lines across Germany, the UK, Australia, and the Netherlands.

Our team (10+ engineers) already has a solid foundation: warehouse, ingestion layer, and ETL pipelines are in good shape. Now we're building the next layer — the one customers and business teams actually interact with. Data products, APIs, predictive analytics, and AI-powered features that move the business from "here's what happened" to "here's what you should do next."

This role is for someone who builds that layer. Not pipelines for their own sake — but data products that get used, make decisions, and ship.

What You'll Actually Be Doing

Building data products end-to-end. Predictive support-load dashboards, automated package optimization based on competitor data, ship-level complaint signals that feed sales decisions — you'll take these from concept to production.

Designing and maintaining the serving layer. APIs, feature delivery, real-time data products built on top of our Redshift warehouse — you own this layer and collaborate with data engineers who own what's beneath it.

Owning reliability after deployment. You monitor, troubleshoot, and optimize what you ship — freshness, performance, and uptime are part of the job, not someone else's problem.

Integrating LLMs into real workflows. We use Claude (Anthropic) and expect pragmatic judgment on when to use prompt engineering, when RAG is the right call, and when fine-tuning actually makes sense. No experimentation for its own sake.

Testing and validating before you ship. New data products and AI features go through proper validation — with attention to baseline metrics and downstream impact — before they touch production.

Moving us toward predictive and prescriptive analytics. We want to go beyond look-back reporting. You'll help define what that looks like architecturally and then build it.

Contributing to our real-time roadmap. We're early in our streaming journey — you'll have genuine input on direction, not just implementation.

Being a technical reference point on the team. You'll be the go-to voice on data product architecture and LLM integration — shaping how the team thinks about these topics, not just executing tasks.

What You Won't Be Doing

• Managing a team or handling people leadership
• Pure ETL/pipeline work — we have engineers for that
• Academic ML research or model experimentation without a production target
•  

You Must Have

• 5+ years building data-intensive applications end-to-end — not only pipelines
• Strong Python; comfortable in JavaScript/TypeScript when the serving layer needs it
• Strong SQL and hands-on experience with a cloud data warehouse (Redshift preferred)
• Experience designing and shipping REST APIs that serve production systems
• Practical LLM integration experience in production — with real judgment on the tradeoffs
• At least one customer-facing or business-critical data product shipped end-to-end
• Hands-on experience with dbt — able to read, extend, and propose changes to models
• Full professional proficiency in English

Strongly Preferred

• Exposure to Airbyte, Airflow, and BI tools such as Tableau
• Frontend competence sufficient to ship a usable internal dashboard independently
• Ability to document architecture and data product behavior clearly — for both technical and business audiences
• Strong architectural judgment and ability to translate business needs into shipped products
• Willingness to push back constructively when the data doesn't support a requirement

Nice to Have

• Experience with streaming / real-time systems (Kafka, Debezium, Materialize, RisingWave, or similar)
• Background in e-commerce, travel, or marketplace businesses
• Experience building agentic LLM workflows in production
• Familiarity with GDPR and EU data residency constraints

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

Ready to help us redefine how people find and book cruises? We’d love to meet you!

About the Role

We are building a game provider aggregator platform from scratch and looking for an Engineering Lead to design the architecture, drive technical execution, and build the engineering team from the ground up. You will be responsible for scalable, high‑load systems that integrate dozens (and later hundreds) of game providers while ensuring reliability, security, and performance for international operators.

Responsibilities

• Define the technical architecture and engineering roadmap of the aggregator platform.
• Lead the design and implementation of scalable, high‑load backend systems (millions of API calls, low latency, fail‑safe flows).
• Build, hire, and mentor the engineering team (backend, frontend, QA, DevOps).
• Own system reliability, security, observability, and incident management.
• Design and supervise the integration framework with game providers and operators (REST/GraphQL, WebSocket, iFrame, etc.).
• Introduce and maintain engineering practices: code quality, CI/CD, testing, monitoring, and documentation.
• Collaborate closely with Product, Business, and Compliance to align technology with commercial goals and regulatory requirements.

Requirements

• 5+ years of experience as a Tech Lead, Engineering Lead, or Senior Backend Engineer (Node.js).
• Strong background in iGaming, casino or sports‑betting platforms, ideally with experience in game aggregators, RGS, or casino‑front systems.
• Hands‑on experience building high‑load, scalable backend systems (distributed services, rate limiting, caching, queues).
• Proven ability to build and manage engineering teams, including hiring, mentoring, and performance reviews.
• Deep understanding of APIs, integrations, microservices, and platform architecture.
• Solid knowledge of Kubernetes, and observability tools.
• Strong communication skills and experience working in a remote, international environment.

Nice to have

• Experience with game aggregation platforms or multi‑provider casino infrastructures.
• Familiarity with payment gateways, affiliate systems, or CRM/analytics stacks used in iGaming.

• Background in startups or fast‑growing companies from early stages.

   

We offer:

• Remote work from anywhere in the world (Mon-Fri from 10:00 to 19:00 Kyiv time)
• Creative and dynamic environment
• The possibility of rapid career growth (companies at the stage of active growth are an ideal place for a rapid take-off)
• The minimum amount of bureaucracy, complete freedom, if it leads to it
• Work with the international market and the main focus on Europe
• We compensate: advanced training courses, foreign language courses, etc.

• Paid vacation and sick leave
