The Essentials
Duration: 4-6 Months (Internship)
Start Date: Jan / Feb 2025
Location: Berlin (Hybrid)
Team Size: 6–10 (Pre-seed)

Overview

We are building a product where mistakes are not UI bugs — they are wrong results for real people. For us, quality starts with correct logic, reliable data handling, and systems that behave predictably under real-world and edge-case scenarios.

We are looking for an early-career engineer with a solid academic foundation and clear growth potential. This role is intentionally designed as a gateway into software engineering. You will start with hands-on manual testing and logical analysis, then gradually move into test automation and writing production code.

We are not hiring a "career QA." We are hiring someone we can grow into a strong engineer.

Purpose of the Role:

• Ensure correctness and stability of core business logic
• Develop a deep understanding of the product, data, and system behaviour
• Grow from QA-focused responsibilities into a full software engineering role

Tasks

Responsibilities:

Manual Testing & Logic Validation (initial focus)

• Perform thorough manual testing of complex business logic and edge cases
• Validate calculations, rules, and data processing across different scenarios
• Reproduce issues reliably and document findings with clear technical context
• Analyze why a system behaves incorrectly, not just where
• Work closely with engineers and product to reason about system behavior

Automation & Development (progressively)

• Add and maintain automated tests (frontend and/or backend)
• Improve test coverage and reliability of critical flows
• Contribute small product features and bug fixes
• Participate in code reviews and technical discussions
• Gradually take ownership of production code

Requirements

What We Expect

Required:

• Bachelor's degree (or in progress, last year) in Computer Science, Software Engineering, Mathematics, or a related field
• Strong analytical and logical thinking
• High attention to detail and accuracy
• Ownership mindset: you care about correctness, not just completion

Strong Plus:

• Basic knowledge of JavaScript / TypeScript
• Understanding of SQL and working with data
• Familiarity with React
• Understanding of testing principles (manual and/or automated)
• Any prior development experience (internships, personal projects, coursework)
• Git / GitHub experience

Benefits

What We Offer

• Real product, real users, real impact
• Direct mentorship from experienced engineers
• Deep exposure to how production systems are built and scaled
• Clear path to becoming a software engineer
• Flexible work setup (hybrid / remote)
• Low bureaucracy, high ownership, high standards

Growth Path

• 0–3 months: Manual testing, domain understanding, product immersion
• 3–6 months: Test automation, first code contributions
• Beyond: Full participation as a Software Engineer + QA automation

This role is explicitly designed for growth. If you perform well, your responsibilities will expand quickly.
