(Senior) Product Engineer (m/f/d) | JobSetuu

Deine Position

You will help shape the virtual assembly line team - our intelligence workflow engine building solutions in Growth and Operations to scale our products globally with maximum efficiency and quality. This is a builder role at the intersection of engineering and product: you co-define what gets built, ship it fast, and use AI as a force multiplier at every step.

As a (Senior) Product Engineer at 1KOMMA5°, you will take end-to-end ownership of features and workflows, making key decisions on architecture, integration layer, and solution design. You'll collaborate closely with product managers, designers, and engineers across teams to ship things that genuinely move the needle for our customers - and you won't be shy about challenging assumptions or proposing a better direction.

Our Stack:

• TypeScript, React / Next.js (frontend) and Node.js / NestJS (backend)
• AI-assisted development with Cursor and Claude Code
• GCP / Vercel, GitHub Actions (CI/CD)
• Linear, Notion, Figma, Miro

Key responsibilities include but are not limited to:

• Own feature development end-to-end, from problem framing to production deployment and long-term maintenance
• Build and integrate AI-powered product experiences using LLMs, agents, and tool-use patterns
• Define feature scope together with PMs - engage with the "why", not just the "what"
• Contribute to architectural decisions, API design, and AI integration patterns across the teams
• Keep feedback loops short: prototype, ship to real users, observe, adjust
• Push back when something doesn't make sense and propose better approaches

Dein Profil

• Strong fullstack proficiency in TypeScript, React / Next.js, and Node.js / NestJS
• Real, demonstrable experience building with LLMs, APIs, or MCPs - production use preferred
• A product and customer mindset: you think about user problems, not just implementation elegance
• Proven ability to own features end-to-end, from rough problem statement to shipped, maintained product

• Excellent written and spoken English; German is a plus
• Residency in Germany Bonus points for:
• Experience with agentic systems, tool-use patterns, or RAG pipelines
• Familiarity with the energy market, construction, sales, or climate tech context
• Prior experience in a startup or scale-up

Benefits

• With your work, you accelerate the "energy transition" and hence have a direct impact on our climate
• Work with and learn from other super-smart colleagues
• You will enjoy direct contact with core decision-makers
• You will enjoy the best chances of entering full-time in one of Europe’s most thriving scaleups

Expert Career Tips for (Senior) Product Engineer (m/f/d) Roles

To succeed in a competitive market as a (Senior) Product Engineer (m/f/d), you need more than just technical skills. Here are some expert strategies to elevate your profile:

• Build a Strong Portfolio: For technical roles, a clean GitHub or a personal project site is essential. For non-technical roles, a case study portfolio demonstrating problem-solving and impact is equally valuable. Show, don't just tell, what you have achieved in your previous positions.
• Master the Narrative: When interviewing, use the STAR method (Situation, Task, Action, Result) to structure your answers. Quantify your results wherever possible—mentioning "increased efficiency by 20%" is much more impactful than saying "improved efficiency."
• Continuous Learning: The industry moves fast. Whether it's staying updated with the latest AI tools or mastering a new management methodology, continuous professional development is key. Consider obtaining industry-recognized certifications that align with (Senior) Product Engineer (m/f/d) requirements.
• Networking: Connect with other professionals in similar roles. Join online communities, attend webinars, and engage in meaningful discussions on professional social networks. Often, the best opportunities come through referrals and community engagement.
• Soft Skills Matter: Communication, empathy, and leadership are often the deciding factors between two equally qualified technical candidates. Cultivate these skills as they are universally valued across all industries and seniority levels.

Additionally, research the specific company's culture and values. Tailoring your application to show how you align with their mission can significantly increase your chances of moving forward in the process.

Comprehensive Application Strategy & Hiring Process

Applying for a new role is a marathon, not a sprint. Follow this strategic approach to maximize your success rate:

1. Initial Research & Tailoring

Don't send the same resume to every employer. Spend at least 30 minutes researching the company. Look for recent news, their product roadmap, and their team structure. Modify your summary and core competencies to reflect the specific keywords found in the job description.

2. The Perfect Cover Letter

If the application allows for a cover letter, use it to tell a story that your resume cannot. Explain why you are passionate about this specific company and how your unique background makes you the perfect fit for the challenges they are currently facing.

3. Navigating the Multi-Stage Interview

Most modern hiring processes involve 3-5 stages. This typically includes a recruiter screen, a technical or skill-based assessment, a peer interview, and a final leadership round. Prepare for each stage differently: focus on enthusiasm and fit for the recruiter, technical depth for the assessment, and strategic vision for the leadership round.

4. Post-Interview Follow-Up

Always send a personalized thank-you note within 24 hours of each interview. Reference a specific topic discussed during the call to demonstrate your active listening and genuine interest in the role.

By following these steps, you demonstrate a high level of professionalism and attention to detail that sets you apart from the average applicant.

Typical Interview Process

1. Resume screening
2. HR call
3. Skill interview
4. Final manager interview
5. Offer

Tip: Research the company's products and culture.

Global Market Intelligence & Relocation Insights

At JobSetuu, we specialize in helping talent navigate the global job market. Here is what you need to know about the current landscape in Hamburg and beyond:

The demand for skilled professionals is increasingly borderless. For roles based in Hamburg, understanding the local cost of living, visa requirements (if applicable), and cultural nuances is vital. If this is a remote role, consider the time zone alignment and the asynchronous communication culture of the hiring organization.

Relocation Support: Many forward-thinking companies offer relocation packages that include moving stipends, temporary housing, and legal assistance with work permits. When evaluating an offer, look beyond the base salary—consider the total compensation package, including equity, bonuses, and healthcare benefits.

Work-Life Balance Trends: Hybrid and remote work have become standard in many regions. Research the local labor laws and common practices regarding work hours and vacation time to ensure the role aligns with your lifestyle goals.

Leveraging JobSetuu's tools can help you compare salaries across different cities and understand the "purchasing power" of your potential offer, ensuring you make an informed decision for your long-term career path.

Skills & Competency Roadmap for Professional Development

To remain competitive in Professional Development, we recommend focusing on the following core competencies over the next 12-18 months:

• Technical Mastery: Deepen your expertise in the core tools and languages relevant to your field. For developers, this might be cloud architecture; for marketers, it might be data-driven attribution modeling.
• AI Augmentation: Learn how to leverage generative AI and automation tools to increase your productivity. Understanding how to integrate these technologies into your workflow is becoming a non-negotiable skill.
• Leadership & Strategy: Even in individual contributor roles, the ability to think strategically and lead projects from inception to completion is highly valued. Focus on stakeholder management and high-level project planning.
• Data Literacy: The ability to interpret data and use it to drive decisions is essential across all business functions. Familiarize yourself with data visualization and basic analytical concepts.

By investing in these areas, you not only prepare yourself for the role you are applying for today but also build a resilient foundation for the opportunities of tomorrow.
