Full Job Description

📋 Description

• Join Pico as a Senior C++ Engineer and become the architect of ultra-low-latency trading systems that move billions of dollars in milliseconds. You will design, build and harden the core C++ engines that power market-data feeds, order-routing gateways and real-time risk checks for tier-one banks, proprietary trading firms and hedge funds across five continents.
• Own the full lifecycle of performance-critical software: from capturing sub-microsecond requirements in trading-room white-board sessions, through writing lock-free data structures and NUMA-aware memory layouts, to deploying hot-swappable shared libraries on bare-metal servers co-located inside global exchanges.
• Optimize every nanosecond—profile kernel bypass drivers, hand-tune compiler flags, benchmark against Solarflare, ExaNIC and Mellanox cards, and squeeze the last CPU cycle out of Intel Ice Lake and AMD EPYC architectures. Your code will run in environments where a 200-nanosecond regression is considered a production incident.
• Partner with quantitative researchers to translate mathematical models into deterministic C++17/20 modules that execute within strict SLA budgets. You will implement pre-trade risk checks, real-time Greeks calculations and basket-hedging algorithms while ensuring thread safety, zero-GC overhead and lock-free publishing to Kafka and Aeron streams.
• Build resilient distributed systems that span multiple data centers and cloud regions. You will craft custom TCP and multicast protocols, integrate with FPGA-based feed handlers, and design failover logic that guarantees microsecond-level recovery when a fiber line is cut or an exchange gateway reboots.
• Champion modern C++ best practices across the global engineering guild. Lead code reviews focused on move semantics, constexpr evaluation, concepts and ranges; mentor junior engineers through pair-programming and weekly tech talks; and drive adoption of Bazel, Conan and sanitizers (ASan, TSan, UBSan) in our CI/CD pipelines.
• Collaborate with DevOps and SRE teams to automate golden-image builds, kernel tuning scripts and immutable container deployments. You will embed observability hooks (eBPF, perf counters, Intel PCM) so that every function’s CPU cache-miss ratio is visible in Grafana dashboards within 30 seconds of deployment.
• Influence product strategy by translating client latency benchmarks into engineering roadmaps. When a hedge fund in Singapore asks for 50-nanosecond faster access to the Osaka Exchange, you will prototype a new UDP multicast channel, run deterministic latency tests on Spirent and present findings to the CTO and sales leadership.
• Maintain a security-first mindset: enforce static analysis (Coverity, PVS-Studio), fuzz critical parsers and participate in red-team exercises. Your code will be scrutinized by internal auditors and external penetration testers because a single buffer overflow could cost millions in market impact.
• Contribute to Pico’s open-source initiatives—upstream patches to the Linux kernel for tick-scheduling tweaks, publish blog posts on lock-free queues, and speak at C++ conferences about the engineering lessons learned while shaving microseconds off the critical path.

🎯 Requirements

• 7+ years of professional C++ development on Linux, including at least 3 years focused on sub-millisecond or ultra-low-latency systems.
• Expert-level knowledge of C++17/20, lock-free programming, memory models, CPU cache hierarchies and kernel bypass networking (DPDK, Solarflare Onload, or similar).
• Demonstrated ability to profile and optimize code using perf, VTune, eBPF, and hardware performance counters to achieve deterministic microsecond-level latencies.
• Strong understanding of TCP/UDP, multicast, kernel networking stack, NUMA topology and hardware timestamping (PTP, PPS).
• Nice-to-have: experience with financial protocols (FIX, OUCH, ITCH), FPGA integration, real-time operating systems, or exchange co-location environments.

🏖️ Benefits

• Fully remote-first culture with flexible hours—work from anywhere while staying connected through Slack, Zoom and quarterly engineering summits in New York, London or Singapore.
• Competitive base salary plus annual performance bonus tied to latency improvements and client satisfaction metrics.
• Annual $3,500 professional development stipend for conferences, courses and certifications (CPPCon, CppIndia, HFT certifications, or advanced kernel internals training).
• Premium medical, dental and vision coverage for you and dependents, plus 401(k) with 6% company match and immediate vesting.
