The CoinDCX Journey: Building the Future of Finance:

At CoinDCX, our mission is clear – to make crypto and blockchain accessible to every Indian and enable them to participate in the future of finance.

As India’s first crypto unicorn valued at $2.45B, we are reshaping the financial ecosystem by building safe, transparent, and scalable products that power adoption at scale.

We believe that change starts together. It begins with bold ideas, relentless execution and people who want to build what’s next.

If you’re driven by purpose and thrive in environments where your work defines the next chapter of an industry, you’ll feel right at home here.

About the Role:

This isn’t a typical Staff Database Engineer role.

You will operate at the core of a high-scale crypto exchange, owning the architecture and reliability of the data layer that powers real-time trading, wallets, and market infrastructure. You’ll design and scale resilient, low-latency database systems capable of handling extreme volatility and transaction throughput. By bridging infrastructure and application layers, you will drive performance, data integrity, and system stability at “crypto-speed.” This role demands deep technical ownership, where your decisions directly impact uptime, risk, and user trust at scale.

What You’ll Do:

Architectural Leadership: Lead the evolution of our global database architecture using Aurora Global Databases to ensure low-latency access and regional failover capabilities.
Performance Engineering: Deep-dive into SQL performance tuning, query execution plans, and indexing strategies. Solve complex concurrency and locking issues inherent in high-throughput financial systems.
Scaling & Capacity Planning: Manage database scaling strategies (Read Replicas, Aurora Serverless v2, and Multi-AZ deployments) to handle massive spikes in traffic during market volatility.
Database Reliability (DBRE): Implement “Infrastructure as Code” (Terraform/CDK) for database provisioning. Automate lifecycle management, including patching, backups, and point-in-time recovery (PITR).
Security & Compliance: Enforce strict encryption-at-rest and in-transit. Implement fine-grained access control (IAM Database Authentication) and audit logging to meet FinTech regulatory standards.
Cross-Functional Partnership: Collaborate with Backend Engineers to optimize data models and access patterns (avoiding N+1 queries, optimizing connection pooling with RDS Proxy).

You’ll Excel in This Role If You:

Expertise in Amazon Aurora: Minimum 5+ years of hands-on experience specifically with RDS Aurora (PostgreSQL or MySQL compatible).
High-Scale Systems: Proven track record of managing production databases with terabyte-scale data and thousands of transactions per second.
AWS Mastery: Deep understanding of the AWS ecosystem, including VPC networking, KMS for encryption, CloudWatch for monitoring, and Performance Insights.
Automation: Proficiency in Terraform, Python, or Go for building database automation tools and CI/CD pipelines.
Database Internals: Strong understanding of transaction isolation levels, MVCC, and write-ahead logging (WAL).

You’ll Know You’re Winning When:

Crypto-Specific Expectations (Preferred):

24/7/365 Mindset: Experience in industries where 5 minutes of downtime equals millions in lost volume.
Data Integrity: Understanding of cryptographic hashing and how to maintain high-integrity audit trails for financial ledgers.
Web3 Familiarity: Experience handling data from blockchain indexers or integrating with nodes is a major plus.
Soft Skills:

Mentorship: Ability to level up Senior and Mid-level engineers through design reviews and “teaching by doing.”
Incident Response: Calm under pressure; ability to lead the “War Room” during critical database outages.
Strategic Thinking: Ability to look 12–24 months ahead to predict where the data bottlenecks will occur as the user base grows.

Why This Role Matters & What’s In It For You:

You gain the unique opportunity to establish the definitive “single source of truth” at scale, moving beyond mere reporting to drive high-stakes innovation in the Web3 space. This is a platform to exercise true ownership, where you will solve industry-defining challenges and elevate the organization’s analytical maturity through visionary leadership and continuous analytical evolution.

Hiring Process:

Here’s what your journey with us looks like:

Application Review – We assess for skills, alignment, and intent
Recruiter Connect – A short conversation to understand you better
Functional Round(s) – Deep dive into your approach, craft, and problem-solving
Assignment / Simulation Round –

Culture & Values Discussion – A conversation to understand our ways of working and how you thrive best
Founder Conversation (Optional) – For certain roles and senior levels, you may meet our founders to explore strategic alignment and long-term fit

Where We Work:

We believe the best ideas emerge when people build together. Collaboration, speed and trust come alive when teams share the same space.

With this belief, we operate as a work-from-office organisation. This role is based out of our Bangalore office, where energy, alignment and innovation move in real time.
