Big Data Engineer (Java Spark Developer – JAVA SPARK EXP IS MUST)

Role Overview

We’re looking for a smart, adaptable, and driven generalist to join the Founder’s Office as an intern. This isn’t your typical internship. 

You'll work directly with the founder, be given context and direction, but execution will be your game. You must know how to break down bottlenecks, navigate ambiguity, and solve problems in your own creative way — while staying aligned with the larger vision.

What You’ll Do

• Shadow & Execute: Work closely with the founder on a wide range of tasks – think strategy, operations, marketing, product, partnerships, and more.
• Problem Solve: Identify bottlenecks and inefficiencies across functions and solve them proactively.
• Take Ownership: Own tasks end-to-end – from planning to execution, while keeping stakeholders updated.
• Wear Multiple Hats: Be ready to switch between roles – researcher, operations ninja, strategist, customer champion – sometimes in the same day.
• Make It Happen: Be resourceful. You’ll often have to find solutions your way – fast, scrappy, and smart.

Who You Are

• A generalist who thrives on variety and new challenges.
• A self-starter – you don’t wait for instructions; you ask the right questions and make things happen.
• Problem-first thinker – you see a roadblock and immediately start thinking of workarounds.
• Comfortable with ambiguity, chaos, and rapid change.
• You believe “done is better than perfect”, but you don’t compromise on quality.
• Strong communicator – both written and verbal.

Nice to Have (But Not Must)

• Past experience in early-stage startups or founder’s office-type roles.
• Exposure to tools like Notion, Google Sheets, Canva, Figma, or Zapier.
• Interest in food, D2C, or brand-building.

Why Join Us

• Direct mentorship from the founder
• Opportunity to work across multiple domains – a crash course in building a startup
• Learn how to operate and scale zero-to-one

• • Be a core part of something that’s just getting started

• Deep tech skills in flutter
• Good programming knowledge of DART
• Knowledge of REST API and JSON
• Self start and dynamic 

• Core Java: advanced level competency, should have worked on projects with core Java development.

• Linux shell : advanced level competency, work experience with Linux shell scripting, knowledge and experience to use important shell commands

• Rdbms, SQL: advanced level competency, Should have expertise in SQL query language syntax, should be well versed with aggregations, joins of SQL query language.

• Data structures and problem solving: should have ability to use appropriate data structure.

• AWS cloud : Good to have experience with aws serverless toolset along with aws infra

• Data Engineering ecosystem : Good to have experience and knowledge of data engineering, ETL, data warehouse (any toolset)

• Hadoop, HDFS, YARN : Should have introduction to internal working of these toolsets

• HIVE, MapReduce, Spark: Good to have experience developing transformations using hive queries, MapReduce job implementation and Spark Job Implementation. Spark implementation in Scala will be plus point.
