Python Developer

About Us:

Tradelab Technologies Pvt Ltd is not for those seeking comfort—we are for those hungry to make a mark in the trading and fintech industry. If you are looking for just another backend role, this isn’t it. We want risk-takers, relentless learners, and those who find joy in pushing their limits every day. If you thrive in high-stakes environments and have a deep passion for performance driven backend systems, we want you.

• We’re looking for a Backend Developer (Python) with a strong foundation in backend technologies and a deep interest in scalable, low-latency systems.

• You should have 3–4 years of experience in Python-based development and be eager to solve complex performance and scalability challenges in trading and fintech applications.

• You measure success by your own growth, not external validation.

• You thrive on challenges, not on perks or financial rewards.

• Taking calculated risks excites you—you’re here to build, break, and learn.

• You don’t clock in for a paycheck; you clock in to outperform yourself in a high-frequency trading

environment.

• You understand the stakes—milliseconds can make or break trades, and precision is everything.

• Develop and maintain scalable backend systems using Python.

• Design and implement REST APIs and socket-based communication.

• Optimize code for speed, performance, and reliability.

• Collaborate with frontend teams to integrate server-side logic.

• Work with RabbitMQ, Kafka, Redis, and Elasticsearch for robust backend design.

• Build fault-tolerant, multi-producer/consumer systems.

What We Expect:

• 3–4 years of experience in Python and backend development.

• Strong understanding of REST APIs, sockets, and network protocols (TCP/UDP/HTTP).

• Experience with RabbitMQ/Kafka, SQL & NoSQL databases, Redis, and Elasticsearch.

• Bachelor’s degree in Computer Science or related field.

Who We are?

At e6data (https://e6x.io/" target="_blank">https://e6data.io) we’re building core algorithms that make querying 25 - 200X more performant (i.e. faster and/or cheaper) than every other analytics platform in the world. This results in billions of dollars of value unlocked across faster analytics, savings on computing/infra, and new use cases become possible.

Our core team has 100+ years of combined experience and 10+ patents across diverse but complementary disciplines like real-time databases, time-series databases, SQL OLAP engines, distributed computing platforms, stream processing, and log analytics. Two of the founding team are second-time founders with past exits.

We are passionate about solving the deepest and most important problems in computer science and believe in making our technology available to customers regardless of their location, size, or budget. Our vision is for e6data to power every analytical workload in the world - regardless of deployment scenario (cloud, on-premise, edge), across every use case (end-user queries, ETL / data pipelines), and every latency requirement (batch, streaming / real-time).

What you will do?

• Write awesome code
• Your primary focus will be on building our product around our core algorithms. You will collaborate with our Performance Engineering and DevOps teams.
• Identify tactical and long-term product improvements (could be code, script, etc.) so that e6data development is based on frictionless onboarding of customers
• Build our internal Data Platform using e6data
• Adding scalable functionality to the core e6data engine for new features like UDFs, SQL functions, etc

What we are looking for?

• Worked with Java for a minimum of 4 years
• Knowledge of SQL Query planning will also be good to have
• A passion for continuous learning and growth (both at a personal and team level)
• Strong team player
• Experience (or enjoys) working in a startup will be an added advantag
