AI-Native Senior Software Engineer (Vibe Coder)

About the role

We are looking for a \"Vibe Coder\" – an AI‑Native Engineer who has moved beyond traditional syntax‑heavy programming to master the art of AI‑assisted and autonomous engineering. You won’t just be writing code; you will be orchestrating it. Your primary skill is not how fast you can type Python or JavaScript, but how effectively you can guide State‑of‑the‑Art (SOTA) LLMs to build complex, scalable, and bug‑free systems at 10x the speed of a traditional developer. You understand that in this new era, natural language is the new programming language.

Key Responsibilities

• High‑Velocity Prototyping: Go from “idea” to “deployed MVP” in hours, not weeks, using AI‑native IDEs (Cursor, Windsurf) and cloud environments (e.g. Replit).
• Agentic Orchestration: Build and manage autonomous AI agents using frameworks like LangChain, AutoGen, or custom scripts to handle multi‑step engineering tasks.
• Architectural Stewardship: Since the AI writes the implementation, your focus shifts to system design, data structures, and ensuring the pieces fit together logically.
• “Vibe” Management (Prompt Engineering): Craft precise, context‑heavy prompts to guide LLMs toward specific outcomes, managing the context window effectively.
• Code Review & Security: Act as the rigorous gatekeeper for AI‑generated code. You must be able to read code faster than you write it, spotting hallucinations, security vulnerabilities, and logic errors instantly.

Tech Stack Requirements

• AI‑Native IDE Mastery: Deep proficiency with Cursor or Windsurf, using these tools to index codebases and context switch effectively.
• LLM Fluency: You know the “vibes” of different models – when to use Claude 3.5 Sonnet for coding logic vs. GPT‑4o for reasoning.
• Frontend Generation: Experience with generative UI tools to rapidly scaffold interfaces.
• Agentic Frameworks: Familiarity with building or using agentic loops (Devin, OpenHands, or simpler RAG pipelines).
• Polyglot Reading Ability: You may not write every language fluently, but you must be able to read and debug multiple languages (Python, TypeScript, Rust, Go) when the AI generates them.

Your Profile

• The “10x” Mindset: You get frustrated by boilerplate and constantly look for ways to automate your own workflow.
• Taste & Intuition: You have a strong product sense. Because you build faster, you have more time to obsess over the user experience (the “vibe” of the product).
• Skepticism: You don’t blindly trust the AI. You verify everything.

Why Us?

At Beroe X nnamu GmbH, we prioritize a balanced work‑life experience.

Benefits

• 4‑Day Work Week & up to 24 Days Paid Vacation – More time to recharge
• Competitive Compensation – Fair salary and comprehensive benefits.
• Flexible Work Arrangements – Work the way that suits you.
• Professional Development – Access to training and certifications.
• Team Events – Bi‑annual company events and quarterly lunch get‑togethers.
• Work Abroad Flexibility – Remote work from the EU or selected non‑EU countries for up to 8 weeks a year with travel insurance coverage.

Work Environment

We operate on a hybrid model with offices in Berlin and Munich, offering a 32‑hour, 4‑day workweek. This means:

• In‑Office Collaboration: Work from the office two days a week.
• Manage Your Own Hours: Flexibility to work around your needs as long as team goals are met.

Our Culture

We are committed to fostering a collaborative, innovative and inclusive work environment where everyone’s ideas matter. We know that diverse teams lead to better outcomes and welcome applicants from all backgrounds.

About Us

At Beroe x nnamu GmbH, we are committed to empowering procurement teams to make informed, strategic decisions that drive real impact. By integrating AI and game theory, our Software as a Service (SaaS) platform, nnamu.negotiations, delivers a groundbreaking approach to complex, yet autonomous negotiations. nnamu.negotiations delivers additional total‑value‑of‑ownership savings efficiently and effectively for buyers with no prior knowledge of game theory required. By combining our world‑class proprietary AI with an unmatched, unique database of over EUR 400bn actual game theory project data we help clients uncover incremental value in their negotiations, driving outcomes that were previously out of reach.

Beroe x nnamu GmbH is now a Beroe, Inc. group entity. Beroe is a global leader in procurement intelligence. Beroe has been on procurement’s leading edge since the company’s founding in 2006, bringing a world of insights forward. The unique combination of Beroe’s expertise, AI tools, and vast amounts of reliable data enable organizations to make smarter, faster, better procurement decisions. Not tomorrow, not today, but now. Selected by ProcureTech as one of the “most pioneering Analytics, Data and Intelligence solutions in 2024”, Beroe helps thousands of organizations sift through the data noise, mitigate risk, face fewer surprises, and ultimately gain a competitive edge.

With nnamu’s cutting‑edge AI and Beroe’s trusted market intelligence, we are unlocking game‑changing possibilities for procurement teams worldwide.

The Challenge We are Solving

Despite the proven potential of game theory to enhance negotiation outcomes significantly – potentially unlocking an incremental USD 1 Trillion of value – its application in business negotiations remains rare, inconsistent, and hard to scale. This gap presents a vast opportunity but also a challenge that many companies have yet to overcome. Beroe x nnamu GmbH is pioneering the use of AI‑powered game theory to make complex negotiation strategies accessible, scalable, and incredibly effective for organizations worldwide.
