Senior Blockchain Backend Engineer

Location: Bengaluru

APEING Labs is building the next generation of on-chain trading and liquidity market intelligence infrastructure across perps, prediction markets, and high-velocity crypto assets. Our goal is not to ship features — it’s to build infrastructure and intelligence layers that users and partners depend on.

This role is for engineers who think from first principles, care deeply about performance and correctness, and want to work on systems where latency, data integrity, and scale actually matter.

The Role
We’re looking for a Senior Blockchain Backend Engineer with deep experience in Web3 infrastructure, DeFi systems, and backend architecture. You’ll be responsible for designing and building mission-critical backend services that power real-time trading, data aggregation, and execution across multiple on-chain environments.
You will work closely with founders and senior engineers to make architectural decisions that define the platform long-term.

What You’ll Work On
High-performance backend services for on-chain trading
Blockchain data ingestion, indexing, and aggregation pipelines
RPC integrations and abstraction layers (Solana / EVM)
Execution, routing, and state-sync systems
Real-time market data, analytics, and user state
Secure key management, secrets, and infra-level safeguards
APIs and services that must be fast, reliable, and correct

Key Responsibilities
Design and implement scalable backend architectures for Web3 products
Build and maintain blockchain-native services with a focus on performance
Own data integrity, correctness, and fault tolerance
Collaborate with frontend, product, and infra teams to ship production systems
Make thoughtful tradeoffs between speed, safety, and scalability
Write clean, well-documented, and maintainable code
Identify bottlenecks, failure modes, and long-term risks before they happen

What We’re Looking For

Required:

6+ years of backend engineering experience
Strong experience with blockchain / Web3 / DeFi systems
Deep understanding of backend fundamentals (APIs, databases, concurrency, caching)

Experience with high-throughput, low-latency systems
Proficiency in one or more backend languages (Go, Rust, Type Script, Python, etc.)
Experience working with cloud infrastructure and CI/CD pipelines
Strong systems thinking and problem-solving skills

Strong Plus:

Experience with Solana and/or EVM chains
Experience building indexers, data pipelines, or RPC services
Familiarity with trading systems or financial infrastructure
Security-first mindset (keys, secrets, access control)
Experience in early-stage or high-ownership environments

Who This Role Is For
Engineers who own systems, not tickets
Builders who care about long-term architecture, not hacks
People who want real responsibility and influence
Those comfortable working with ambiguity and high standards
This is not a junior role, and not a place to coast.

Why Join
Build foundational infrastructure in a fast-growing Web3 space
High ownership and direct influence on technical direction
Work with an ambitious team focused on execution and quality
Competitive compensation based on experience and impact
Opportunity to help shape a category-defining platform
