As a Data Engineer at Reply, your day-to-day work will be highly dynamic and project-driven. You will act as a technical consultant, meaning your responsibilities will extend beyond pure coding to include system design and client communication.

Your primary technical responsibility will be the end-to-end development of data pipelines. This involves designing automated ETL/ELT workflows that extract data from diverse sources (APIs, relational databases, NoSQL stores, flat files), transform it to meet business logic, and load it into analytical data stores. You will write clean, modular, and well-tested code in Python or Scala, and deploy these pipelines using containerization tools like Docker and orchestrators like Kubernetes.

Collaboration is a core aspect of life at Reply. You will work closely with Data Scientists to prepare features and deploy machine learning models into production environments. You will also collaborate with Product Managers and Business Analysts to understand client requirements and translate them into technical specifications. Frequently, you will present your technical architectures directly to client stakeholders, explaining the benefits of your design choices and ensuring alignment with their business objectives.

Additionally, you will be responsible for ensuring the reliability, security, and performance of the data platforms you build. This includes implementing robust monitoring and alerting systems, optimizing storage and compute costs in the cloud, and ensuring data governance and compliance policies (such as GDPR) are strictly adhered to throughout the data lifecycle.

To be competitive for a Data Engineer position at Reply, you need to demonstrate a strong mix of technical expertise and professional consulting skills.

• Must-have skills – Strong proficiency in Python and SQL; solid understanding of relational and non-relational database design; familiarity with at least one major cloud provider (AWS, GCP, Azure); and a strong academic background in a STEM field.
• Nice-to-have skills – Experience with Apache Spark, Databricks, or Snowflake; familiarity with containerization (Docker, Kubernetes); knowledge of infrastructure-as-code (Terraform); and experience working in an Agile development environment.

For entry-level and junior positions, Reply places a very high value on your academic performance. Having a master's degree in Computer Science, Engineering, Physics, Mathematics, or a related discipline, along with a high graduation grade, is highly advantageous and can directly impact your starting salary offer. For senior roles, a proven track record of delivering scalable data solutions in production and leading technical teams is highly prioritized.

Q: How difficult are the technical interviews at Reply? A: The difficulty is generally rated as average to easy for well-prepared candidates. If you have a solid grasp of Python, standard SQL queries, and basic data structures, you will find the technical rounds highly manageable. The focus is more on fundamental problem-solving and logic than on hyper-complex algorithmic puzzles.

Q: How long does the entire recruitment process take? A: On average, the process takes about 2 to 4 weeks. It begins with a central HR call, followed quickly by introductions to specific business units. However, because the units operate independently, some specialized teams may take longer to schedule technical rounds or finalize offers.

Q: What is the working model at Reply? A: Reply generally operates on a hybrid working model. Depending on the client's needs and your specific business unit, you can expect a mix of remote work and office-based collaboration, with occasional travel to client sites.

Q: How does the decentralized company structure affect my role? A: It means you will be hired by a specific Reply sub-company (e.g., Data Reply). Each sub-company has its own focus, culture, and client portfolio. This structure offers the agility and tight-knit feel of a boutique consultancy, backed by the resources and stability of a large global parent company.

To set yourself apart during the Reply selection process, keep these practical tips in mind.

• Master your thesis presentation: If you are a recent graduate, your thesis is your primary calling card. Be ready to explain your research clearly, highlighting the data challenges, the technologies you chose, and why you chose them. Practice delivering this explanation in under five minutes.
• Over-communicate your logic: During coding challenges, do not code in silence. Talk your interviewer through your approach, explain why you are choosing specific data structures, and discuss the trade-offs of your solution.

• Research the specific Reply company: Before your technical round, find out which specific Reply company (e.g., Data Reply, Sensei Reply) you are interviewing with. Research their specific focus areas and recent projects so you can tailor your questions and show genuine interest in their niche.
• Be proactive and ask questions: Show your consulting potential by asking insightful questions at the end of the interview. Ask about the typical tech stacks on their current projects, how they handle client requirements, or how career progression is structured within their specific business unit.
