Job description
Experience: 5.00 + years Salary: Confidential (based on experience) Expected Notice Period: 15 Days Shift: (GMT+05:30) Asia/Kolkata (IST) Opportunity Type: Remote Placement Type: Full Time Contract for 6 Months(40 hrs a week/160 hrs a month) (*Note: This is a requirement for one of Uplers' client - Agentic AI Platform) What do you need for this opportunity? Must have skills required: Open-source database contributions, ANN Indexing, cloud-native/self-service databases, Concurrency handling, Rust, Vector indexing, vector search tools, C, C++ Agentic AI Platform is Looking for: Role Description Extend our existing database with native vector capabilities—data types, ANN indexes, query planning, and developer APIs—so applications can run hybrid (sparse+dense) search at production scale with ACID guarantees. • Role- Senior Software Engineer • Experience Required: 5+ years • Shift Time: 12:00 PM to 9:00 PM IST remotely • Job Type: Full Time Contract for 6 months- Extendible • Payroll- Uplers Talent Solutions • Device- Talent has to use their own device Skills Vector data model • New VECTOR/EMBEDDING column types, distance operators (L2, cosine, dot), and server-side normalization. • Ingestion/backfill pipelines for embeddings; bulk loaders and online updates. ANN indexing in the DB • Production-grade HNSW / IVF-Flat / IVF-PQ (and variants) in C/C++. • Persistence integrated with WAL/checkpoints/snapshots; crash safety and fast recovery. • Index lifecycle: online CREATE INDEX … USING HNSW/IVF, background build/merge, partial rebuilds, compaction/vacuum, tombstone handling. Transactions, MVCC & consistency • Visibility rules for vector rows/segments under MVCC; point-in-time queries; repeatable reads for ANN. • Write path that avoids long stalls; predictable p95/p99 latency under mixed read/write workloads. Query planner / optimizer integration • New planner nodes and cost model for ANN; predicate/column pushdown; hybrid plans (BM25/keyword + vector + filters). • Join strategies (e.g., ANN-first with LATERAL, or filter-first then re-rank); parameterized search (ef, nprobe, pq_m, recall_target). Distributed operations • Replication/streaming of vector indexes; shard placement & rebalancing; hot-index warmup. • Rate/CPU/RAM isolation per tenant; guardrails for memory growth and tail latency. APIs, SDKs & tools • SQL syntax, gRPC/HTTP endpoints, and SDKs (Python, Java, Node.js) aligned with existing drivers. • Admin surfaces: collection/index management, backups, restore, zero-downtime upgrades. • Observability: metrics, traces, pg_stat-like views for ANN, slow-query analyzer. Minimum Qualifications • 6–10+ years building performance-critical systems in C/C++, plus one of Python/Node/Java. • Deep knowledge of data structures, concurrency, memory layout, profiling, and low-latency I/O. • Hands-on with search/vector stacks (FAISS, hnswlib, ScaNN, NMSLIB, Milvus, Qdrant, Vespa, Lucene/Elasticsearch/OpenSearch) or custom engines. • Experience integrating with database internals (WAL, MVCC/ACID, query planning, storage engines). Nice to have: • SIMD (AVX2/AVX-512/NEON), GPU/CUDA/ROCm, or FPGA acceleration. • LSM/B-tree/columnar storage, compaction strategies, snapshot/backup/restore. • Re-ranking (MMR, late interaction/ColBERT), PQ/OPQ/SQ quantization, workload-aware autotuning. • Multi-tenant resource isolation; k8s ops; packaging (static, musl, cross-compile). • Developer-tooling craftsmanship (docs, CLIs, codegen, examples). Interview Rounds • 1st round : Screening round (BGV, Technical expertise, current technical stack, etc) • 2nd round: Virtual interview (looking for existence contribution, as this is very specific need) • 3rd round- If needed How to apply for this opportunity? • Step 1: Click On Apply! And Register or Login on our portal. • Step 2: Complete the Screening Form & Upload updated Resume • Step 3: Increase your chances to get shortlisted & meet the client for the Interview!
