Skalar is building the future of tax, accounting, and payroll using AI, and the company is looking for a Senior Data Engineer to join its early core team in Munich. This is not a seat-warmer role. You would be the first data engineer at the company, responsible for architecting the entire data foundation from the ground up.

The opportunity comes with above-market pay and meaningful equity. It also comes with serious expectations. Here is what you need to know before you apply.
What Skalar Actually Does
Skalar is an AI-powered platform targeting one of the most persistent pain points in business: taxation, accounting, and payroll. Every company must handle these processes continuously, yet most existing tools are clunky, slow, and error-prone.
The founding team is not new to this game. They have collectively scaled businesses to tens of millions of users, generated tens of millions in revenue, and delivered nine-digit exits. Skalar is backed by leading venture investors and is expanding across multiple countries.
This context matters when you apply. Skalar is not a lifestyle startup. It moves fast, sets high standards, and expects its engineers to operate at the same level.
What the Role Actually Involves
As the first Data Engineer at Skalar, you own the full data stack. There is no existing architecture to inherit and no senior data colleague to ask for help. You are building from zero.
The core responsibilities include:
- Architecting the greenfield data warehouse from scratch, end-to-end
- Building resilient ETL and ELT pipelines to process large volumes of financial data
- Integrating messy third-party APIs and financial data sources into clean, usable formats
- Establishing data governance frameworks, quality checks, and security protocols
- Ensuring absolute data integrity for sensitive financial and employee information
- Potentially hiring and mentoring junior engineers as the team grows
The job description frames the mission as taking data infrastructure from "v1 to v10." That language signals that Skalar wants someone who can not just build but also scale what they build over time.
The Skills Skalar Is Looking For
Skalar has not published a rigid checklist of qualifications, but the role description makes the technical and behavioral requirements clear. Strong candidates will demonstrate depth in both areas.
Technical Skills
- Proven experience designing and building cloud-based data warehouses (Snowflake, BigQuery, or Redshift are common choices at this stage)
- Deep knowledge of ETL and ELT pipeline design, including tools like dbt, Apache Airflow, or Prefect
- Experience processing and transforming financial data from external APIs and third-party integrations
- Strong understanding of data governance, access controls, and security best practices for sensitive data
- Proficiency in SQL and at least one scripting language, typically Python
- Familiarity with streaming or batch data processing frameworks
- Experience working in cloud environments, particularly AWS, GCP, or Azure
Behavioral and Leadership Skills
- Comfort operating in ambiguous, early-stage environments without defined processes
- Ability to make architectural decisions independently and defend them clearly
- Genuine interest in mentoring and building a data team from scratch
- Strong communication skills, especially when translating technical decisions for non-technical stakeholders
The "Senior" label here carries real weight. Skalar needs someone who has already made mistakes on other teams and learned from them, not someone still in learning mode on the fundamentals.
How the Hiring Process Likely Works
Skalar has not published a detailed breakdown of its interview stages. However, early-stage startups with experienced founding teams tend to follow a similar structure for senior technical hires. Based on the company profile and role, here is what candidates should prepare for.
Stage 1: Application Review
Your resume goes directly to a small team, likely including a founder. There is no large HR department filtering applications at this stage. Keep your CV clean, specific, and focused on measurable outcomes. Mention the scale of data you have worked with, the systems you have built, and the business problems your work solved.
Stage 2: Introductory Call
Expect a 30 to 45-minute conversation with a founder or a senior team member. This call is about mutual fit. They want to understand your background quickly and assess whether you can communicate clearly. You should also be asking sharp questions about their current data stack, the biggest problems they face, and what success looks like in the first 90 days.
Stage 3: Technical Assessment
This stage typically involves a take-home case study or a live technical interview. At Skalar, the focus will almost certainly involve pipeline architecture, data modeling, and handling messy financial data. Expect scenarios where there is no clean answer, and you need to walk through trade-offs explicitly.
Stage 4: Final Interview with Founders
The final round usually involves meeting multiple founders or senior team members. This is where culture fit, ambition, and judgment get tested. Skalar's founders have operated at high levels before. They will notice quickly if you hedge too much or fail to take a clear position on technical choices.
Interview Tips Specific to This Role
Generic interview advice will not get you far at a company like Skalar. The team has seen hundreds of candidates across multiple ventures. You need to bring something specific.
Talk about the hard parts of past projects. Skalar is building infrastructure for sensitive financial data. They need to trust you with that. Sharing stories about where things broke, what you did wrong, and how you fixed it shows maturity and honesty.
Prepare a point of view on modern data stack choices. Should they use dbt? Snowflake or BigQuery? Airflow or a lighter orchestration tool? You do not need the perfect answer. You need a clear, reasoned one.
Ask about the product roadmap and how data connects to it. Showing that you think beyond pipelines and into business outcomes signals the kind of senior-level thinking Skalar is looking for.
Finally, come ready to discuss leadership. Even if managing a team is not your immediate goal, Skalar explicitly mentions hiring and mentoring as part of the role. Demonstrating that you have thought about how to build a data team shows you are thinking long-term.
How to Stand Out as a Candidate
Hundreds of data engineers exist in the Munich market and across Germany. The ones who get calls back from early-stage, high-caliber teams tend to do a few things differently.
- Reference fintech or financial data experience prominently. Skalar works with highly regulated, sensitive data. Prior experience in finance, payroll, or accounting software is a genuine differentiator.
- Show evidence of greenfield work. If you have built a data warehouse from scratch before, say so clearly and describe the decisions you made.
- Demonstrate you understand data as a product. Mention how your work enabled analysts or scientists to do better work downstream.
- Keep your application focused and direct. No long cover letters with generic enthusiasm. One or two sharp paragraphs that show you have read the job description carefully will go further.
Skalar is at an early and consequential stage. The person who fills this role will have a real impact on the company's direction, not just its codebase. Candidates who approach the application that way, with ambition, specificity, and a genuine interest in the problem Skalar is solving, are the ones most likely to move forward.
