    Salary: £80,000–£100,000 + EMI Share Options + Private Medical Insurance

    Position Overview

    Are you an experienced C++ developer who enjoys solving complex engineering challenges where precision and performance truly matter? At Hoptroff, we take care of time, literally.

    We build nanosecond-accurate, software-driven timing systems used by global investment banks, telecoms operators, and broadcasters. Our technology powers MiFID II-compliant trade timestamping and supports critical systems where milliseconds simply aren’t precise enough.

    We’re entering an exciting phase of growth and are looking for a Senior C++ Developer to join our high-calibre engineering team. You’ll write modern C++ (C++20+) at the core of our Linux-based timing and synchronisation platform, working on performance-sensitive systems where correctness and determinism are critical.

    You’ll own significant platform components, influence architecture decisions, and collaborate closely within a small, highly collaborative engineering team.

    What You'll Do:

    • Design, build, and optimise low-latency, high-precision C++ systems at the heart of our timing products

    • Make architectural decisions balancing performance, maintainability, observability, and real-world timing constraints

    • Develop online and offline tooling supporting time synchronisation and system monitoring

    • Build and maintain automated test cases using Python-based frameworks

    • Provide senior technical input across Product, QA, Hardware, and commercial discussions

    • Support, mentor, and review work alongside junior developers

    • Help shape engineering standards, tooling, and development processes

    What We’re Looking For:

    • Extensive experience writing modern C++ in production environments

    • Strong understanding of C++20/23 features including concepts, ranges, coroutines, and constexpr principles

    • Proven experience building low-latency, performance-sensitive Linux systems

    • Strong computer science fundamentals including algorithms, concurrency, optimisation, and system design

    • Experience designing architecture and making sound technical trade-offs

    • Strong debugging and profiling experience using tools such as perf, valgrind, sanitizers, or flame graphs

    • Experience with Git, CI/CD pipelines, CMake, and modern testing frameworks

    • Excellent communication and problem-solving skills

    Nice to Have:

    • Linux networking experience (sockets, networking concepts, tooling)

    • Experience interacting with hardware and low-level Linux interfaces

    • Windows systems development experience

    • PostgreSQL or relational database experience

    • Python and/or Go (Golang) experience

    • Familiarity with PTP and NTP time synchronisation protocols

    • Open-source contributions or active involvement in modern C++ developments

    • Interest in AI tooling and emerging technologies

    Why Join Us:

    • Salary £80,000 - £100,000 depending on experience

    • EMI Share Options

    • Private Medical Insurance

    • Hybrid flexibility with 2 days in our Shoreditch office

    • Work from a thriving Shoreditch FinTech environment with networking and social events

    • Your work directly supports global financial markets, broadcasters, and telecoms infrastructure

    • High ownership and meaningful technical impact

    • A collaborative team invested in continuous learning and modern tooling
