Role: Senior Quant Developer (HFT / Low-Latency)
Location: [Istanbul / Onsite]
Type: Full-time
About Us
At Ahlatci Holding, we build real-time trading and risk systems designed for low latency, high throughput, and production reliability. We turn research into measurable execution performance.
The Role
You’ll own critical parts of the market data → signal → order → execution pipeline, building deterministic, observable, and low-latency components suitable for HFT environments.
What You’ll Do
- Build low-latency market data pipelines (tick/order book/trade streams)
- Create quant models/strategies with strong engineering discipline for production
- Track execution quality: p50/p99/p999 latency, slippage, fill-rate, quote-to-fill drift
- Ensure backtest/live consistency (replay, idempotency, ordering guarantees)
- Profile and optimize CPU/memory, contention, GC pressure, kernel/network settings
- Improve observability (metrics/logs/traces) and contribute to incident/postmortem practices
Requirements
- 5+ years in trading systems / market data / low-latency engineering
- Strong in C++ / Rust / Java / Go (at least one)
- Deep understanding of concurrency, backpressure, batching, cache locality
- Linux performance tooling (perf/flamegraphs), CPU pinning, NUMA awareness
- Streaming & caching experience (Kafka/NATS, Redis) and data stores (Postgres/ClickHouse/Time-series)
Nice to Have
- FIX/WebSocket/REST exchange integrations, OMS/EMS, risk engines
- Kernel-bypass familiarity (DPDK/XDP) and NIC/network tuning
- PTP time sync and timestamp accuracy/clock drift handling
- Low-latency cloud architecture experience (AWS/GCP), Docker/K8s
