Fullstack Software Engineer (m/f/d) - Price Alert

At idealo, we help millions of users around Europe find the perfect moment to buy – so they never miss a great deal again. Our team is behind the Price Alert, Wishlist, and Price Chart: three core features that empower users to make smarter shopping decisions across web and app. From detecting the best deals to delivering timely notifications, we create meaningful experiences that inspire trust and drive long‑term engagement together with our partner teams.

We are looking for a Software Engineer (m/f/d) who is passionate about building new product features, enjoys working across disciplines, and is eager to continuously improve and learn together with their team.

About your new role

• You design, implement, and operate scalable services and APIs for price alerts, wishlists, and price charts, ensuring reliability and high availability.
• You help design and optimize notification pipelines (app push, e‑mail, etc.) to make sure messages are timely, relevant, and valuable to users.
• You improve our price‑based features (e.g., price history, alerts, and insights) by enhancing performance, data quality, and user experience.
• You collaborate closely with Product, Data, App, and Web teams, conduct experiments/A‑B tests, and use data to make informed decisions that improve user engagement.
• You contribute to our architecture, observability (monitoring and alerting), and CI/CD setup, with services running on AWS in a continuous delivery environment.

Skills & Requirements

Tech Skills

• Solid experience in TypeScript, React, and Python, with a focus on building API‑driven solutions (REST/JSON).
• Practical experience in cloud environments (AWS), including infrastructure as code, CI/CD, and monitoring.
• Understanding of scalable, event‑driven systems (queues/streams) and asynchronous jobs.
• Familiarity with data modeling for time series or historical datasets, and experience with both document‑oriented and relational databases.
• Nice to have: Experience with web/app feature integrations (wishlist, price alerts), experimentation/ A‑B testing, or serverless architectures.

Mindset & People Skills

• Collaboration and knowledge sharing are at the heart of how we work. Learning from each other and growing together as a team comes naturally to you.
• You communicate feedback and new ideas openly and respectfully, helping us continuously improve.
• Change and innovation are seen as opportunities – you’re curious, adaptable, and enjoy experimenting with new technologies.
• Taking ownership of the quality, reliability, and performance of your work is something you care about.
• Strong English communication skills are essential; German is a plus.

At idealo you can expect

• You need vacation? We offer you 30 days of vacation. Not enough? You can “buy” an additional 15 days every year by converting your salary and it's seen as a positive thing.
• You want to further your education? We take your personal development goals seriously and, in addition to our idealo Learning Hub, e‑learning offerings (e.g., Udemy), coaching & mediation, we also offer you the opportunity to benefit individually from additional learning and development budget.
• And what about the office? Our office in the heart of Berlin offers excellent free lunch, as well as free coffee, lemonades and after‑work beer, in addition to the “standard foosball”. It also has a fabulous rooftop terrace with view of the whole of Berlin where you can network with colleagues from our group of companies.
• You want full flexibility on your way to work and beyond? No problem with a job bike or Deutschlandticket‑ and it's environmentally friendly, too!
• You don't live in Germany yet? We support you in the visa process and with your relocation.
