Database Developer Lead Database Engineer

About This Role

This high-impact role at Avathon is at the intersection of low-level systems programming, distributed storage, and query engine optimization, focusing on building core database technology from the ground up rather than application-level software. The role suits an experienced Database Engineer to lead the architecture, design, and deployment of engine-level database systems across high-performance, large-scale environments.

Responsibilities

• Design and implement storage layers using LSM Trees, B-Trees, RocksDB, LevelDB, LMDB, Wired Tiger, or custom engines
• Build efficient key-value storage layouts, secondary/composite indexes, inverted indexes, spatial indexes, and vector indexes
• Design high-throughput pagination, cursor mechanics, and large-scale dataset iteration patterns
• Optimize write/read amplification, compaction strategies, caching layers, and Bloom filters
• Implement Raft or Paxos consensus, data partitioning/sharding strategies, and multi-node replication
• Architect resilient systems capable of automated leader election, failure recovery, dynamic retries, and partition handling
• Integrate service discovery (etcd, Consul, Zoo Keeper), distributed tracing/observability, zero-downtime rolling upgrades, back-ups, and storage format compatibility layers
• Work with MVCC, Snapshot Isolation, Optimistic Concurrency Control (OCC), and Two-Phase Locking (2PL)
• Implement WAL (Write-Ahead Logging), crash recovery guarantees, deadlock detection, and distributed transactions (2PC)
• Build and optimize query execution plans, join algorithms, predicate pushdowns, and distributed query execution pipelines
• Write production-grade C++17/20, Rust, Java, or Scala code focused on low-overhead memory management, profiling, and benchmarking
• Ensure transactional correctness and data integrity via distributed fault injection, property-based testing, and consistency validation suites

Requirements

• Hands-on experience with Janus Graph/Titan, Neo4j, Tiger Graph, Amazon Neptune, Dgraph, or a custom in-house graph engine
• Strong understanding of graph storage models, traversal algorithms, graph indexing, and distributed graph processing
• Familiarity with graph query languages such as Gremlin, Cypher
