Our mission is to change this world by making blockchain accessible to everyone in everyday life. 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.

We 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.

Requirements:

We'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.

The 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.

We 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.

• Linux: Advanced administration and OS-level tuning — real-time OS configurations, cgroups, CPU isolation, memory management, and low-level network stack configuration.
• Hardware 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.
• Networking & 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).
• Performance Engineering: Practical experience profiling latency-sensitive systems; familiarity with tools such as perf, flamegraph, strace, tcpdump, eBPF, and hardware performance counters.
• Containerization: Deep knowledge of Docker and Kubernetes, including low-overhead deployment patterns and performance trade-offs of containerized workloads.
• IaC: Proven track record with Ansible, Terraform, and Helm in production environments.
• Monitoring: Hands-on experience with the Prometheus / Grafana stack; ability to build latency-aware dashboards and alerting (P99, jitter, throughput KPIs).
• Scripting: Solid scripting in Bash and Python; Golang is a strong plus given its role in systems tooling.
• CI/CD & Secret Management: Strong grasp of CI/CD pipelines with experience integrating performance validation stages; familiarity with Vault for secrets management.
• Security: Understanding of DevSecOps principles and Kubernetes security policies.

Key Performance Metrics You'll Work With

Latency Distribution - P99 / P99.9 across the tick-to-trade path, using hardware-level timestamps (NIC/PTP).

Jitter - variance between min/max latency, measured over large sample sets in live market conditions.

Throughput - messages per second (orders + cancels) under exchange burst scenarios.

System Reliability - сontinuous monitoring of uptime

Extra Credit / Big Pluses

• Hands-on experience with kernel-level optimization: syscall reduction, network stack bypass (DPDK, RDMA, Solarflare OpenOnload).
• Background in HFT, algorithmic trading, or other ultra-low-latency production environments.
• Experience with hardware timestamping, PTP/IEEE 1588, and precision time synchronization.
• Familiarity with colocation operations and exchange connectivity (cross-connects, proximity hosting).
• Proven SRE track record with formal SLO/error budget frameworks in latency-sensitive contexts.
• DevSecOps: vulnerability scanning, Zero Trust, RBAC, and secure delivery pipelines.
• Understanding of business processes in FinTech, crypto, or electronic trading.

Responsibilities:

• Low-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.
• Cloud & 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.
• Hardware & 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.
• Infrastructure as Code (IaC): Automate provisioning and configuration of high-performance environments using Ansible, Terraform, and Helm - with performance reproducibility as a first-class requirement.
• Latency 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.
• CI/CD for Performance: Build and maintain CI/CD pipelines that include automated latency regression testing, so performance degradations are caught before they hit production.
• Monitoring & Observability: Design and operate comprehensive latency monitoring and alerting systems (Prometheus, VictoriaMetrics, Grafana) - including hardware timestamping (NIC/PTP) and fine-grained performance telemetry.
• Colocation & 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.
• High Availability & DRP: Design systems that maintain stability and reliability under peak load while continuously pushing latency lower - zero regressions, always.
• Cross-Team Collaboration: Work alongside algo developers, quant teams, and network engineers to ensure trading strategies execute with minimal infrastructure overhead.

What you'll do

Design the math

Nice to have

-Build math models for slots — paytables, reel strips and weights, feature probabilities, RTP breakdown per feature, hit rate, volatility profile, max win and max exposure

-Run large-scale simulations (100M+ spins) to confirm the model behaves as designed, and iterate until the play experience matches the design intent

-Turn game concepts from designers into workable models — and pitch your own concepts when you see an opportunity

Ship it and prove it
-Write math implementation specs that engineers can build from without guessing

-Validate and sign off the math engine: verify the implementation against your model, and help troubleshoot discrepancies

-Prepare math documentation for certification labs (GLI, BMM, iTech Labs) and support the certification process

-Write statistical summaries that a producer or an account manager can actually read

Keep it healthy
-Support and tune released models and features; analyse live performance data and feed it back into new designs

Must have
-2+ years of hands-on slot math

-Strong probability theory and combinatorics — you can derive a distribution, not just simulate it

-Python for simulation and analysis (NumPy / pandas / SciPy or equivalent)

-Advanced Excel: building and reverse-checking par sheets, pivots, validating simulation output against

closed-form math

-Degree in Mathematics, Statistics, Computer Science or equivalent — or a portfolio strong enough that we stop asking

-English B2+ — you'll write specs and certification documentation, and correspond with labs and

partners

-Genuine interest in games. You should have opinions about why one bonus feature feels better than another

Nice to have
 

-Table games or bingo math (house edge, side bets, prize-pool distribution, pattern probabilities,

card/ball draw models) — or a clear appetite to learn it, since our roadmap includes all three

-C++ or another compiled language, for working close to the math engine

-Familiarity with regulatory frameworks (MGA, UKGC, Ontario, GLI standards) and responsible-gaming constraints

-SQL / BI tools for live-performance analysis

Build the Brand. Drive Inbound. Make Things Happen.

We’re looking for a hands-on Marketing Manager with iGaming industry knowledge who can turn ideas into execution, build a strong B2B brand, and drive measurable business growth.

We’re a product and technology company with deep roots in iGaming, building technology solutions for a global market. We already have the foundations in place — now we want someone who can take our marketing to the next level.

This is your chance to own digital marketing end to end, move fast, experiment boldly, and see the direct impact of your work.

We’re not looking for someone who just manages agencies, coordinates meetings, or creates endless marketing plans. We need a doer: someone who can write, launch, test, analyze, and improve — using modern AI tools to move faster and deliver more.

What You’ll Do

• Own and Grow the Brand

Take ownership of our existing brand positioning and make it more recognizable, relevant, and memorable across the iGaming B2B market. Help operators, aggregators, and industry decision-makers understand who we are, what we offer, and why we matter.

• Turn Marketing into an Inbound Lead Engine

Build and execute campaigns that attract potential customers through SEO/GEO, content, paid advertising, social media, and email marketing. Your mission is to create demand and bring the right people to us — not chase prospects through cold outreach.

• Create Content That Gets Attention

Develop compelling content that speaks the language of the iGaming industry: website copy, landing pages, LinkedIn posts, articles, email campaigns, case studies, and other assets that build credibility and generate interest.

You’ll use AI tools to accelerate research, writing, creative production, and analysis — while keeping the output relevant, authentic, and high-quality.

• Own the Channels That Deliver Results

Manage and improve our website, landing pages, LinkedIn and other social channels, email marketing, paid campaigns, PR, and event-related marketing. Prioritize the channels that create the strongest impact rather than spreading effort everywhere.

• Move Fast. Test. Learn. Improve.

Launch campaigns without getting stuck in endless planning and approval cycles. Set ambitious goals, track performance, learn from the data, and continuously improve conversion and lead generation.

• Work Across the Business — Without the Bureaucracy

Collaborate with product experts, Sales, the event team, and company leadership to keep messaging accurate, campaigns relevant, and priorities aligned. Bring people together when needed, make decisions within your area of ownership, and keep things moving.

What We’re Looking For

• Real iGaming industry experience — our top priority. You’ve worked in B2B marketing for an iGaming technology company, platform provider, game systems vendor, aggregator, operator, or a similar business. You understand the industry, its stakeholders, how buying decisions happen, and what makes B2B customers pay attention.
• A hands-on marketing mindset. You can write copy, create and launch campaigns, manage channels, work with basic design tools, and analyze results yourself. You don’t need an agency to get things done.
• Strong B2B marketing expertise. You understand long sales cycles, trust-building, lead generation, account-focused marketing, and the importance of aligning marketing with Sales.
• AI is part of your workflow. You actively use AI tools for research, content, creative work, analytics, and productivity — and you’re always exploring better ways to work.
• A bias for action. You take ownership, make decisions, experiment, and focus on measurable outcomes rather than activity for activity’s sake.

• Excellent English. You can confidently create marketing content and communicate with an international audience. Experience adapting messaging for different markets and cultures is a strong advantage.

   

Nice to Have

• Existing connections with iGaming operators, aggregators, or other industry players.
• Experience with SEO/GEO, paid search or social campaigns for B2B technology products, and marketing automation.
• Understanding of how licensing and local regulations influence marketing across different markets.

• Basic design skills with Figma or Canva, or experience using AI tools to produce visual and video content.

   

What Makes This Role Different?

• Ownership from day one: You’ll have the freedom to shape and execute marketing, not just follow someone else’s playbook.
• Real impact on business growth: Your work will directly contribute to brand awareness, inbound demand, and commercial opportunities.
• AI-powered execution: Use modern tools to move faster, produce more, and continuously improve how marketing gets done.
• A product-driven environment: Work closely with people who build the technology and understand the industry.

• Room to experiment: We value initiative, smart decisions, quick iterations, and tangible results over unnecessary meetings and lengthy approval chains.

   

What To Expect From Digicode?

🌎 Work from Anywhere: From an office, home, or travel continuously if that’s your thing. Everything we do is online. As long as you have the Internet and your travel nomad lifestyle doesn’t affect the work process (you meet all deadlines and are present at all the meetings), you’re all set.

💼 Professional Development: We offer great career development opportunities in a growing company, international work environment, paid language classes, conference and education budget, & internal 42 Community training.

🧘‍♂️ Work-life Balance: We provide employees with 18+ paid vacation days and paid sick leave, flexible schedule, medical insurance for employees and their children, monthly budget for things like a gym or pool membership.

🙌 Culture of Openness: We’re committed to fostering a community where everyone feels welcome, seen, and heard, with minimal bureaucracy, and a flat organization structure.

And, also, corporate gifts, corporate celebrations, free food & snacks, play & relax rooms for those who visit the office.

Ready to Make an Impact?

Bring your ideas, your industry expertise, and your drive. Let’s make something happen.
