WhiteBIT is a global team of over 1,200 professionals united by one mission — to shape the new world order in the Web3 era. Each of our employees is fully engaged in this transformative journey.\n\nWe work on our blockchain platform, providing maximum transparency and security for more than 8 million users worldwide. Our breakthrough solutions, incredible speed of adaptation to market challenges, and technological superiority are the strengths that take us beyond ordinary companies. Our official partners include the National Football Team of Ukraine, FC Barcelona, Lifecell, FACEIT and VISA.\n\nRequirements:\n\nWe're looking for a Senior / Staff-level engineer with an open mind and a builder's instinct - someone who goes beyond executing tasks and is ready to own the High-Performance practice end-to-end: establish engineering processes, drive R&D, evaluate and champion new technologies, and lead their adoption in production.\n\nThe ideal candidate can bridge the gap between business requirements for low latency and high throughput and the realities of existing infrastructure - translating \"we need to be faster\" into an actionable technical roadmap. You bring a fresh perspective, know how to organize the work, and are equally comfortable optimizing a hardware parameter and presenting a strategy to stakeholders.\n\nWe expect 5+ years of hands-on experience as a DevOps/SRE/Systems Engineer in performance-critical environments - and the maturity to grow yourself and grow a team around you.\n\nLinux: Advanced administration and OS-level tuning — real-time OS configurations, cgroups, CPU isolation, memory management, and low-level network stack configuration.\n\nHardware Internals: Deep understanding of CPU power and performance states (C/P-states), Hyper-Threading / SMT trade-offs, TX/RX ring configuration, and the full data path from NIC through PCIe to memory and CPU. Ability to reason about and tune each stage of that path under production load.\n\nNetworking & TCP Internals: Deep knowledge of TCP/IP — congestion control, ACK behavior, buffer tuning, and protocol-level latency sources. Strong Linux networking fundamentals: low-latency NIC configuration, bypass networking technologies (DPDK, RDMA), and market connectivity (multicast feeds, co-location networks, VPNs).\n\nPerformance Engineering: Practical experience profiling latency-sensitive systems; familiarity with tools such as perf, flamegraph, strace, tcpdump, eBPF, and hardware performance counters.\n\nContainerization: Deep knowledge of Docker and Kubernetes, including low-overhead deployment patterns and performance trade-offs of containerized workloads.\n\nIaC: Proven track record with Ansible, Terraform, and Helm in production environments.\n\nMonitoring: Hands-on experience with the Prometheus / Grafana stack; ability to build latency-aware dashboards and alerting (P99, jitter, throughput KPIs).\n\nScripting: Solid scripting in Bash and Python; Golang is a strong plus given its role in systems tooling.\n\nCI/CD & Secret Management: Strong grasp of CI/CD pipelines with experience integrating performance validation stages; familiarity with Vault for secrets management.\n\nSecurity: Understanding of DevSecOps principles and Kubernetes security policies.\n\nKey Performance Metrics You'll Work With\n\nLatency Distribution - P99 / P99.9 across the tick-to-trade path, using hardware-level timestamps (NIC/PTP).\n\nJitter - variance between min/max latency, measured over large sample sets in live market conditions.\n\nThroughput - messages per second (orders + cancels) under exchange burst scenarios.\n\nSystem Reliability - сontinuous monitoring of uptime\n\nExtra Credit / Big Pluses\n\nHands-on experience with kernel-level optimization: syscall reduction, network stack bypass (DPDK, RDMA, Solarflare OpenOnload).\n\nBackground in HFT, algorithmic trading, or other ultra-low-latency production environments.\n\nExperience with hardware timestamping, PTP/IEEE 1588, and precision time synchronization.\n\nFamiliarity with colocation operations and exchange connectivity (cross-connects, proximity hosting).\n\nProven SRE track record with formal SLO/error budget frameworks in latency-sensitive contexts.\n\nDevSecOps: vulnerability scanning, Zero Trust, RBAC, and secure delivery pipelines.\n\nUnderstanding of business processes in FinTech, crypto, or electronic trading.\n\nResponsibilities:\n\nLow-Latency Infrastructure Ownership: Design, deploy, and continuously optimize infrastructure for latency-sensitive trading systems — market data handlers, order/deal gateways, and risk check engines. Own the full stack from bare metal to application delivery. Define and maintain a reference architecture for low-latency connectivity when onboarding new trading venues, including reproducible configuration baselines, validation procedures, and performance acceptance criteria — so every new venue goes live on a proven, optimized stack.\n\nCloud & Hybrid Network Connectivity: Design, implement, and maintain complex low-latency network solutions for cloud provider interconnects - including cross-connects and Direct Connect / ExpressRoute links between cloud regions, hybrid on-premise/cloud topologies, and high-throughput inter-server fabrics. Ensure both latency minimization and fault tolerance at every layer: physical redundancy, failover routing, and path diversity across providers and regions.\n\nHardware & OS Stack Tuning: Go deep on the full hardware and OS stack - CPU pinning, C/P-states, HT/SMT configuration, NUMA topology, IRQ affinity, TX/RX ring sizing, NIC offloading, and network stack bypass (DPDK/RDMA where applicable). Understand the complete data path from NIC through PCIe to memory and CPU - and optimize every hop.\n\nInfrastructure as Code (IaC): Automate provisioning and configuration of high-performance environments using Ansible, Terraform, and Helm - with performance reproducibility as a first-class requirement.\n\nLatency Profiling & Benchmarking: Systematically profile and debug latency hotspots across the full execution path. Establish and maintain SLA/SLO targets; track P99/P99.9 distributions, jitter, and throughput - not just averages.\n\nCI/CD for Performance: Build and maintain CI/CD pipelines that include automated latency regression testing, so performance degradations are caught before they hit production.\n\nMonitoring & Observability: Design and operate comprehensive latency monitoring and alerting systems (Prometheus, VictoriaMetrics, Grafana) - including hardware timestamping (NIC/PTP) and fine-grained performance telemetry.\n\nColocation & Network Placement: Research, evaluate, and manage optimal server placements - colocations, cross-connects, proximity hosting. Work closely with network and infrastructure teams to minimize physical and logical distance to exchanges.\n\nHigh Availability & DRP: Design systems that maintain stability and reliability under peak load while continuously pushing latency lower - zero regressions, always.\n\nCross-Team Collaboration: Work alongside algo developers, quant teams, and network engineers to ensure trading strategies execute with minimal infrastructure overhead.\n\nWorking terms\n\nImmerse yourself in Crypto & Web3:\n\nMaster cutting-edge technologies and become an expert in the most innovative industry.\n\nWork with the Fintech of the Future:\n\nDevelop your skills in digital finance and shape the global market.\n\nTake Your Professionalism to the Next Level:\n\nGain unique experience and be part of global transformations.\n\nDrive Innovations:\n\nInfluence the industry and contribute to groundbreaking solutions.\n\nJoin a Strong Team:\n\nCollaborate with top experts worldwide and grow alongside the best.\n\nWork-Life Balance & Well-being:\n\nModern equipment.\n\nComfortable working conditions, and an inspiring environment to help you thrive.\n\n24 calendar days of paid leave.\n\nAdditional days off for national holidays.","description_format":"text","description_chars":8007,"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":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Blockchain & Crypto","Cryptocurrencies","Crypto Exchanges"],"lifecycle":[{"event":"open","at":"2026-10-29T12:21:41Z"}],"visa":[],"liveness":{"score":68,"band":"ok","label":"Likely open","p_open":1,"p_active":0.752,"p_room":0.9,"age_days":10,"expected_fill_days":28,"reasons":["seen:10","win:mid"],"computed_at":"2026-10-30T05:48:23Z"},"pay":null,"html_url":"https://alion.io/job/whitebit-seniorstaff-devops-engineer-high-performance-solutions","json_url":"https://alion.io/job/whitebit-seniorstaff-devops-engineer-high-performance-solutions.json","meta":{"generated_at":"2026-10-30T10:07:50Z","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":14554,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-31T00:00:00Z"}},"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":175925},"rest":"https://alion.io/mcp/rest/get_company?id=175925"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fwhitebit-seniorstaff-devops-engineer-high-performance-solutions"},{"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%2Fwhitebit-seniorstaff-devops-engineer-high-performance-solutions"},{"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%2Fwhitebit-seniorstaff-devops-engineer-high-performance-solutions"},{"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/whitebit-seniorstaff-devops-engineer-high-performance-solutions\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fwhitebit-seniorstaff-devops-engineer-high-performance-solutions"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":3454649}},{"tool":"search_jobs","arguments":{"company":"whitebit.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":3454649},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
