• Execute Zoho CRM and Zoho Creator implementation tasks based on defined requirements • Develop, customize, and optimize Zoho applications • Write and maintain Deluge scripts (automation, validations, integrations) • Collaborate with internal developers and communicate progress clearly • Deliver clean, functional solutions with minimal supervision

• You’ll be working on our data team focused on the quality of the datasets being delivered for training our models. • This is a hands-on role where your #1 mission would be to improve the quality of the pretraining datasets by leveraging your previous experience, intuition and training experiments. • This role particularly focuses on generating synthetic data at scale and determining the best strategies to leverage such data into training large models. • You’ll closely collaborate with other teams like Pretraining, Postraining, Evals, and Product to define high-quality data needs that map to missing model capabilities and downstream use cases. • Staying in sync with the latest research in synthetic data generation and pretraining is key to success in this role. • You will constantly lead original research initiatives through short, time-bounded experiments while deploying highly technical engineering solutions into production. • With the volumes of data to process being massive, you'll have a performant distributed data pipeline together with a large GPU cluster at your disposal. • To deliver large, high-quality, and diverse synthetic datasets mixing natural language and code modalities to train best-in-class coding agents.

Role Description We are looking for a Backend Developer to join an experienced team of developers and help design and implement backend services, data models, and processes. We are searching for an analytical mind capable of crafting abstractions and solutions for problems imposed by the business domain and coding those abstractions using our preferred programming languages. Our focus is on OOP in Scala. While we may use some FP concepts and best practices from time to time, we are not an FP shop. Our development follows the Domain Driven Design methodology. Responsibilities - Design and code backend services. - Contribute to a process involving several transformation steps, starting from an idea (or a business need) and crystallizing it into a relevant domain model. - Code the domain model and spin it up to run our business 24/7. - Engage in the following delivery cycle phases: - A Business Domain: It is a customer's business of interest. - Model of a customer domain: A constrained and purified view of a business domain, in the form of diagrams, drawings, text descriptions, pictures, and specifications. - Model codified in a high-level programming language: High-level abstractions with Domain Specification Language, which compiles into a lower-level programming language. - Model codified in lower-level programming languages: This phase involves coding skills through Scala, Java, and PostgreSQL. - Java Bytecode: Trust in Java compilers without interference. - Machine Instructions: Produced at runtime by bytecode interpretation and JIT compilation. Qualifications - At least 10 years of experience working in backend development with Scala/Java or equivalent. - Good knowledge of OOP/FP paradigms and design patterns. - Hands-on experience in working with transactional systems and concurrency. - Independence in work. - Fluency in English is essential. Requirements - Experience with one of these databases: PostgreSQL, Oracle, MSSQL, or DB2. - Familiarity with Domain-Driven Design approach. - Experience with debugging and performance tuning of applications and servers. Benefits - A skills-oriented organization with experienced experts in software architecture and development. - An abundance of development opportunities. - Interesting and challenging tasks, spanning multiple engineering concerns (features, security, performance, CI/CD, architecture, observability, concurrency, etc.). - Strong product department where developers' opinions are seriously taken into account. - An international and learning environment full of passionate and talented people. - Great work-life balance. Important This opportunity is available only for B2B contractors based in Serbia. The role includes onsite onboarding in Zagreb, as well as occasional business travel. If you’re a senior backend engineer who enjoys domain modeling, clean abstractions, and long-living systems, we’d love to hear from you!
