Job Description
About the RoleWere building a next-generation execution engine to power credit-bureaugrade decisioning: high-throughput, low-latency, fault-tolerant, and compliant by design. As the Lead C++ Engineer, you will own core components of the enginescheduling, orchestration, data pipelines, caching, concurrency primitives, and observability. Youll work closely with architects, data/ML teams, and InfoSec to deliver a production-grade platform that scales across markets and bureau integrations (e.g., CIBIL, Experian, TransUnion, Equifax).
Key Responsibilities- Architecture & Design
- Lead design of a C++ microkernel-style execution engine: task graph execution, DAG scheduling, and resource-aware orchestration.
- Define execution semantics (idempotency, retries, deadlines, circuit breakers, backpressure).
- Own API contracts (C++14/17/20), IPC, and integration boundaries with microservices and data services.
- Core Engineering
- Implement low-latency, multi-threaded components using modern C++ (std::thread, atomics, lock-free structures where appropriate).
- Optimize for throughput and latency: memory management, allocator strategies, NUMA-awareness, cache locality, SIMD where needed.
- Build stateful/stateless operators, configurable pipelines, and a rule/evaluator engine for credit decision flows.
- Implement resilience patterns: snapshotting, write-ahead logs, replay, exactly-once/at-least-once semantics where warranted.
- Data & I/O
- Develop high-performance I/O connectors for credit bureaus and internal systems (HTTP/gRPC, message queues like Kafka/RabbitMQ).
- Handle PPI/PII data safely with encryption-at-rest/in-transit, tokenization, and masking.
- Reliability & Observability
- Productionize with tracing, metrics, logs (OpenTelemetry/Prometheus/Grafana), SLOs, and golden signals (latency, error rate, saturation).
- Establish automated tests, property-based tests, fault injection, and performance baselines.
- Leadership & Collaboration
- Mentor a team of 36 engineers; drive code reviews, design reviews, and engineering standards.
- Partner with Product, Risk, and Compliance to align delivery with FCRA/GLBA/GDPR, PCI-DSS where applicable, and local RBI/Credit Information Companies Regulations (India).
- 8+ years of professional C++ development; 2+ years leading/owning complex components or teams.
- Strong with modern C++ (C++17/20): templates, RAII, move semantics, smart pointers, concurrency primitives.
- Hands-on with multi-threading, async I/O, lock-free/concurrent data structures, and performance profiling (perf, VTune, valgrind).
- Experience building high-throughput, low-latency backend systems (sub-10ms p50 targets).
- Deep understanding of networking protocols (HTTP/2, gRPC, TLS), serialization (Protobuf/FlatBuffers).
- Linux systems expertise: memory, filesystems, containers (Docker), build systems (CMake, Bazel), CI/CD.
- Strong focus on testing (unit/integration), observability, and operational excellence.
- Credit bureau integrations: CIBIL/TransUnion, Experian, Equifax (schema handling, retry/backoff, SLAs).
- Rule engines (Drools-like), DAG/scheduler frameworks, or stream processing (Flink/Spark) concepts applied to C++ runtimes.
- Distributed systems: consensus (Raft/Paxos), leader election, partitioning, and replication.
- Security & Compliance: FCRA, GLBA, GDPR, RBI guidelines; PCI-DSS controls; secrets management (Vault/KMS).
- Caches (Redis/memcached), Kafka, gRPC eco-system, and OpenTelemetry.
- Financial risk/scorecards, policy override workflows, and auditability requirements.
- Exposure to Rust/Go in systems components is a plus.
