Tipico

<div>Company Description 
We are Tipico, Germany's leading sports betting provider and one of the most dynamic tech companies in the industry. We approach every challenge like a Championship match, with a mission to excite the arena and elevate the betting experience for every customer. Our culture is energetic and ambitious&mdash;we play as a team to win high, leave an impact, and commit to excellence. Fueled by our passion for the perfect product, we use the newest tech stack to get better every single day.
At Tipico, we believe in owning our game. Are you ready to kick-start your career, learn from experienced professionals, and grow as a software engineer? Then show us your game face - because we're looking for a (Junior) Java Developer (m/f/x) to join our team! 
Job Description 
Start your journey with us, bring your ideas to the table, and develop products that maximise the thrill of sports for our customers. You&rsquo;ll work in a collaborative and agile environment alongside experienced developers who will support you in building your technical skills and growing your career.
Your playing field:<ul><li>
Build software hand-in-hand with AI agents. Using AI to design, write, review and ship code is becoming core to how we work, not an afterthought &mdash; you'll grow into steering agents effectively as part of your daily craft.</li><li>
Develop full-stack applications, primarily powered by Java in the backend and React in the frontend, within a modern and continuously evolving technology landscape.</li><li>
Support the design, implementation and maintenance of end-to-end solutions, choosing the right technologies for each problem rather than being locked into a single framework.</li><li>
Work closely with experienced engineers across the entire software development lifecycle, from concept to production.</li><li>
Participate in code reviews, pair programming and knowledge-sharing sessions to continuously sharpen your craft.</li><li>
Own your contributions end to end &mdash; from clean, well-tested code to the supporting documentation that makes your work usable by the whole team.</li></ul> 

Qualifications 
Which skills you should bring to the pitch:<ul><li>
Education. Bachelor's or Master's degree in Computer Science, Software Engineering, or a related field, or equivalent practical experience.</li><li>
AI-native way of working. This is what matters most to us. AI is already an integral part of your toolbox &mdash; you have a feel for how LLMs behave, you know how to steer an agent toward a good result, and you naturally work with tools such as MCPs and skills. You can hardly imagine building software without AI agents at your side.</li><li>
Engineering foundation. First hands-on experience with Java &mdash; through internships, working-student positions, university or personal projects, or professional work &mdash; as a solid foundation to build on rather than the limit of what you want to do.</li><li>
Ecosystem fluency. Besides core technologies like Java, you have a solid understanding of the supporting ecosystems and frameworks (for example Spring and the wider JVM and web landscape).</li><li>
Software engineering. Interest in software architecture, clean code, and software development best practices.</li><li>
Databases. Basic understanding of different database technologies, such as relational (SQL) and document-based databases.</li><li>
Version control. Familiarity with Git and collaborative version control workflows.</li><li>
Cloud &amp; DevOps. Curiosity about cloud technologies, containerization (Docker/Kubernetes), and CI/CD processes.</li><li>
Innovation &amp; growth mindset. You welcome change and like being at the edge of what's possible. Reading about new tools, trying them out and experimenting feels natural to you &mdash; and you bring a strong drive to learn, develop new skills and take on new challenges.</li><li>
Collaboration. A collaborative mindset with good communication skills and the ability to work effectively in cross-functional teams.</li><li>
Language. Good command of English, both written and spoken, as English is the primary language of communication in an international team.</li></ul> 

Additional Information 
This is how we score with you:<ul><li>
Established International Group. We have a solid foundation on which to grow.</li><li>
Personal and Professional Growth. We offer you opportunities to develop and grow to unlock your potential.</li><li>
Relocation Support. To make your move to Karlsruhe as smooth as possible.</li><li>
Business Bike Leasing. We offer a sustainable commuting solution whilst also keeping you active!</li><li>
Corporate Pension Scheme (betriebliche Altersvorsorge). Secure your future! Join our corporate pension scheme where we provide additional financial support.</li><li>
eGym. We encourage an active lifestyle and to support this we&rsquo;ve partnered with an online sports platform that provides access to a variety of clubs and offers across Germany.</li><li>
Modern offices. Our very own Karlsruhe campus provides an open-plan space with the latest technology.</li><li>
Events. Sponsored Charity and Team gatherings, we like to have fun together as one team and reinforce our connections.</li><li>
Supportive Environment. We believe in collaboration and working together as a team, but we also give importance to the uniqueness of each and every one of us.</li><li>
You choose your own hardware. MacBook or Windows? We love tech and this helps us stay ahead.</li></ul>

Clera

<div>
 We&rsquo;re a German founding team that just raised a $3M pre-seed round from top-tier investors and we&rsquo;re now looking for a Founding Engineer from the DACH region to join us in our San Francisco Hackerhouse. We&rsquo;ll fly you out, cover your visa sponsorship, and bring you directly into the center of the action.
 
 
 This is a once in a lifetime opportunity for the most ambitious engineers in DACH to build alongside us in SF and shape the future of AI recruiting.
 
 
 
 About Clera
 
 :
 
 
 Clera is a fast-growing AI start-up reimagining how top talent finds their dream jobs. We&rsquo;re already working with leading, VC-backed startups such as Mintlify, Luminai, and Windsurf - many in AI, all VC-backed. We believe recruitment needs to be talent-first to make it easy to get in touch with those companies, be coached in the journey and actually get hired. We just raised our big pre-seed and are now growing as quickly as possible.
 
 
 Thousands of talents engage with Clera every week. We&rsquo;ve connected many of them with companies where they&rsquo;ve landed exciting new roles. With the traditional $600B headhunting industry ripe for AI-driven disruption, we are aiming to build a massive company, providing better outcomes for talents and companies. We&rsquo;re at a pivotal moment&mdash;right before liftoff. Early enough that you&rsquo;ll get meaningful ownership.

 Your Experience
 
 :

 </li>
 <li>
 Startup mindset - high agency, resourceful, and obsessed with creating value
 
 
 </li>
 </ul>
 
 Who You Are
 
 :
 
 
 <ul>
 <li>
 Take full ownership of projects, from concept to deployment and do whatever it takes to get the job done.
 </li>
 <li>
 Write code fast and scrap it even faster, but know when to transition to building for scale and quality.
 </li>
 <li>
 Enjoy talking to customers and iterating based on feedback.
 </li>
 <li>
 Are willing to work hard, to create something new with a lot of impact, changing how millions of talents find their jobs in the future.
 
 
 </li>
 </ul>
 
 Tech stack
 
 : TypeScript, React, Cursor, Supabase, Prisma, Typesense, LLM APIs, Trigger.dev
 
 
 
 Working in hacker-house in SF:

 Live &amp; build with a small founding team
 </li>
 <li>
 Zero commute, 10&times; feedback loops &amp; team bonding
