Data & Marketing Automation Consultant / Bloomreach Specialist

Adastra

Bratislava

Apply on the employer's site

Role description

Forget "marketing automation specialist" — think of yourself as a data detective and campaign architect rolled into one. You'll work with the top data-rich companies in the region, using
Bloomreach
(one of the most progressive customer data platforms out there) to figure out what customers actually want, then build the systems that deliver it — in real time.

One day you're digging through web and app behavior data to spot a pattern no one noticed. The next, you're in a room with a client's marketing team, sketching out their customer journey on a whiteboard. The day after that, you're presenting results to stakeholders who want to know exactly how your work moved the needle.

Please note that this position is open only to applicant in Slovakia.

Status: Employee contract (2900 EUR brutto). Salary expectations depend on the seniority level and we are open to speak about it.

What You Bring to the Table

  • A university degree in something data/marketing-adjacent — Data Science, Business Analysis, Marketing, Economics, Predictive Analytics, or similar.
  • 4+ years
    getting your hands dirty in CRM or data analytics — e-commerce, finance, telco, gaming, whatever the industry, as long as you've done the work.
  • Solid
    SQL
    skills — you're comfortable, not just familiar.
  • Working knowledge of
    HTML & JavaScript
    — enough to build and personalize campaigns.
  • Bonus points if you've touched
    Bloomreach
    , Adobe/Salesforce Marketing Cloud, HCL Unica, Acoustic, or SAS Marketing tools — but if not, we'll get you there.
  • English that's sharp enough for client conversations (B2+); Slovak at a conversational level (C1+).
  • A genuine curiosity about data, marketing, and how the two collide — this isn't a "learn it on the job and tolerate it" role, it's a "get excited about a good dataset" role.
  • The confidence to lead a conversation, and the humility to ask good questions.

Employee perks, benefits

You'll grow, fast.
Access to Adastra's full knowledge pool, a personalized development plan, and Adastra Academy — trainings, certifications, workshops, and language courses that actually matter for your career, not just a box to tick.

You'll work on stuff that matters.
Leading marketing automation platforms, international projects, and a team that's young, dynamic, and doesn't take itself too seriously.

You'll actually have a life outside work:

  • 🎿
    Adastra Skiing
    — four days in Austria or Italy, on us.
  • 🏃
    Adastra RUN
    — for the people who make excuses about "no time to train."
  • 🏋️
    Multisport card
    — access to hundreds of gyms, studios, and pools.
  • 🌿
    Health Days
    — workshops on wellbeing, nature, and actually taking care of yourself.
  • 🎉
    Teambuilding that isn't cringe
    — genuinely social, not forced.

And if life gets bigger:

  • A weekend in the Slovak mountains for you
    and
    your family (kids included — carnival, creative workshops, the works).
  • A wedding bonus if you're taking that step.
  • A new baby bonus, plus a day off to actually enjoy it.
  • Even your birthday gets a present.

Sound Like You?

If you'd rather solve a real customer data puzzle, this is the room you want to be in.

We look forward to working with you, and you becoming an Adastran!

In case of interest, do not hesitate to send us your CV in English language.

Data Engineer

Software Engineer - Agentic Engineering

Swiss Re

Bratislava

Apply on the employer's site

Role description

P&C Re Engineering is looking for a Software Engineer to help build and evolve the AI and agentic systems behind our reinsurance business. This is a hands-on engineering role for someone who enjoys shipping production software, is fluent — or eager to become fluent — with agentic coding tools, and wants to work at the frontier of applied AI. It is a contract engagement within one of our business-line squads.

Agentic Engineering builds and runs AI and agentic systems for reinsurance — across Claims, Treaty and Facultative lines — on the platforms the firm already runs. While this is a hands-on engineering role, it rewards a strong product and quality mindset: you will own the software behind a line's AI systems and lead its development toward genuinely agentic systems.

What you will do

As a Software Engineer in the team, you will build, evolve and run the software behind a line's AI systems — the services and workflows that LLM-based agents use. You will work day-to-day with agentic coding harnesses (e.g. Claude Code): breaking work into well-scoped tasks, directing AI agents to build and modify code, and reviewing their output with calibrated scrutiny — spec-first, tested, and accountable for what your agents produce. You will work closely with the Product, Architecture and Domain Delivery organisations.

If You Join Us, You Will For Example

  • Maintain, refactor and extend the line's AI applications and services in production
  • Build agentic-friendly software: the tools, services and workflows that LLM-based agents call
  • Design AI workflows that combine models, prompts, tools, enterprise data, and business logic
  • Validate model behavior, outputs, and assumptions from a production and business-use perspective
  • Design and maintain evaluation frameworks for AI/LLM systems, including test suites and human evaluation workflows
  • Write evaluations and quality checks for agent behavior, and build in grounding and assurance
  • Ensure reliability, scalability, cost control, and latency optimization
  • Help bring new agentic systems into production

We are a small, senior and hands-on team working at the frontier of applied AI for reinsurance. Our focus on agentic engineering connects us: we invest in the tools and patterns that let a small team deliver outsized impact, and we expect everyone to share what they learn.

About You
Nobody is perfect and meets 100% of the requirements. If you meet many of the criteria below and are excited to build production AI systems with agentic tooling, we would be happy to meet you.

In order to be successful in the role, you bring:

  • Strong software engineering: a modern language (Python, TypeScript, or Java / Kotlin), clean code, automated testing, CI/CD
  • A Forward Deployed Engineer mindset — a desire to understand the business problem, the impact the solution makes, and to drive pragmatic decisions towards realising it
  • API / service / integration engineering
  • Familiarity with LLM application patterns (prompting, retrieval-augmented generation, tool / function calling) and an appetite for agentic development
  • Comfort working with agentic coding harnesses (e.g. Claude Code) — directing AI agents and reviewing generated code — and in a Linux / cloud environment
  • The ability to pick up and improve an existing codebase
  • Exposure to Data Science methods in validating AI models

It Is a Strong Plus If You Also Have

  • Hands-on agentic / LLM application development (agent loops, evaluations, tool design)
  • Experience with Palantir Foundry / AIP (valued, not required)
  • Insurance or reinsurance domain exposure
  • Experience with cloud AI services (e.g. Azure AI)

Even if you do not tick every box, but are eager to grow into this role and work at the frontier of agentic engineering, we encourage you to apply.

Thank you for taking the time to read our job advertisement. We look forward to getting to know you.

Role
For Slovakia the base salary range for this position is between [EUR 2,400] and [EUR 4,100] per month (for a full-time role). The specific salary offered considers:

  • the requirements, scope, complexity and responsibilities of the role,
  • the applicant’s own profile including education/qualifications, expertise, specialisation, skills and experience.

In addition to your base salary, Swiss Re offers an attractive performance-based variable compensation component, designed to recognise your achievements. Further you will enjoy a variety of global and location specific benefits.

Eligibility may vary depending on the terms of Swiss Re policies and your employment contract.

About Swiss Re
Swiss Re is one of the world’s leading providers of reinsurance, insurance and other forms of insurance-based risk transfer, working to make the world more resilient. We anticipate and manage a wide variety of risks, from natural catastrophes and climate change to cybercrime. Combining experience with creative thinking and cutting-edge expertise, we create new opportunities and solutions for our clients. This is possible thanks to the collaboration of more than 15,000 employees across the world.

Our success depends on our ability to build an inclusive culture encouraging fresh perspectives and innovative thinking.

In our inclusive and flexible environment everyone can bring their authentic selves to work and their passion for sustainability.

If you are an experienced professional returning to the workforce after a career break, we encourage you to apply for open positions that match your skills and experience.
