These include:BullishExchange - a regulated and institutionally focused digital assets spot and derivatives exchange, integrating a high-performance central limit order book matching engine with automated market making to provide deep and predictable liquidity. Bullish Exchange is regulated in Germany, Hong Kong, and Gibraltar.CoinDeskIndices - a collection of tradable proprietary and single-asset benchmarks and indices that track the performance of digital assets for global institutions in the digital assets and traditional finance industries.CoinDeskData - a broad suite of digital assets market data and analytics, providing real-time insights into prices, trends, and market dynamics.CoinDeskInsights - a digital asset media and events provider and operator ofCoindesk.com, a digital media platform that covers news and insights about digital assets, the underlying markets, policy, and blockchain technology.\nReports to:\nDirector, EngineeringEngineering Organization & Culture\nAt Bullish, we are engineering the institutional standard for the digital asset industry. Our mission is to build a platform where security and compliance are the foundational core, requiring a commitment to technical excellence that goes beyond simply delivering code. We operate as a global engineering organization, setting a high bar in a demanding environment for those driven to do the best work of their careers alongside world-class peers.\nWe value engineers who treat development as a craft and own the outcome from concept to deployment. You will be expected to navigate the unknown, bring structure to ambiguity, and help shape the frameworks and processes that drive our global teams forward. We refuse to compromise on quality and seek problem solvers who thrive on high-impact technical challenges.\nThe Team: Trading Platform Engineering\nThe Trading Platform Engineering team is responsible for designing and optimizing the high-performance, mission-critical foundation that powers our trading activities. Operating at the intersection of software and hardware, the team builds low-latency systems that demand expert-level proficiency in Linux kernel internals, networking pipelines, and distributed systems architecture. The team focuses on architectural excellence, reliability, determinism, and the relentless elimination of tail latency.\nWhat You’ll Do\nHigh-Performance Service Development:Design, build, and optimize high-performance systems using C and Java.\n\nKernel & User Space Engineering:Engineer performance-critical components across user space and kernel interfaces, focusing on memory, scheduling, I/O, and networking paths.\n\nAdvanced Networking:Develop and tune networking pipelines (multicast/unicast UDP and TCP) and implement kernel-bypass or fast-path networking (e.g., DPDK, XDP).\n\nKernel Optimization:Interact with and optimize Linux kernel subsystems, including memory management, schedulers, device drivers, and filesystems (VFS).\n\nLatency & Determinism:Optimize systems for deterministic latency through CPU isolation, thread pinning, NUMA locality, cache awareness, and lock contention reduction.\n\nDistributed Systems:Apply distributed systems patterns, such as sequencer (virtual synchrony), for total ordering and consistency.\n\nProfiling & Debugging:Use tools like perf, strace, eBPF, and flame graphs to identify and eliminate system bottlenecks.\n\nOperational Excellence:Collaborate cross-functionally to deliver robust production systems with clear SLOs, reproducible performance tests, and actionable runbooks.\n\nWhat You’ll Bring\nLanguage Mastery:Expert-level proficiency in Java\n\nLinux Internals:Deep understanding of Linux kernel internals, including memory management, driver models, and scheduler tuning.\n\nLow-Latency Expertise:Practical experience in end-to-end latency optimization, jitter reduction, and techniques like lock-free or wait-free programming.\n\nNetworking Depth:Experience with socket options, buffer sizing, epoll, io_uring, RSS, and NIC queue configuration.\n\nDistributed Systems Knowledge:Understanding of sequencer-based total order broadcast, partial order broadcast and the tradeoffs between latency, throughput, and availability.\n\nConcurrency & Systems:Solid understanding of concurrency, synchronization primitives, and memory models.\n\nAnalytical Mindset:A focus on measurement over assumption, using benchmarks and profiles to drive decisions and communicate complex tradeoffs.\n\nCollaborative Craftsmanship:Commitment to high code quality through rigorous reviews, mentoring, and clear documentation.\n\nNice To Haves\nTrading Infrastructure:Experience in financial markets (e.g., market data, order routing, or FIX/exchange-native protocols).\n\nTime Synchronization:Familiarity with PTP or other high-precision time synchronization for low-latency environments.\n\nObservability:Experience using eBPF and tracing for observability in production.\n\nHardware Interfacing:Knowledge of RDMA, NIC offloads (TSO, LRO), or experience maintaining kernel modules and device drivers.\n\nJVM Tuning:Experience with low-latency JVM practices and deterministic GC tuning for Java-based systems.\n\nAdvanced Benchmarking:Deep knowledge of benchmarking methodology, including workload design and variance analysis.\n\nBullish is proud to be an equal opportunity employer. We are fast evolving and striving towards being a globally-diverse community. With integrity at our core, our success is driven by a talented team of individuals and the different perspectives they are encouraged to bring to work every day.","description_format":"text","description_chars":5688,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Crypto Exchanges","Digital Media"],"lifecycle":[{"event":"open","at":"2026-08-24T00:00:00Z"}],"visa":[],"liveness":{"score":72,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.795,"p_room":0.9,"age_days":54,"expected_fill_days":87,"reasons":["conf:0","win:mid"],"computed_at":"2026-10-17T05:46:00Z"},"pay":null,"html_url":"https://alion.io/job/bullish-lead-engineer-trading-platform-engineering-2","json_url":"https://alion.io/job/bullish-lead-engineer-trading-platform-engineering-2.json","meta":{"generated_at":"2026-10-18T16:47:21Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":22312,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-19T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":4184},"rest":"https://alion.io/mcp/rest/get_company?id=4184"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbullish-lead-engineer-trading-platform-engineering-2"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fbullish-lead-engineer-trading-platform-engineering-2"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fbullish-lead-engineer-trading-platform-engineering-2"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/bullish-lead-engineer-trading-platform-engineering-2\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbullish-lead-engineer-trading-platform-engineering-2"}]}
