Jobs at Djinni

We are a senior engineering team hiring a backend engineer for a long-term role inside a client's product team. The client is a product company with a large user base. We share its name only with engineers who pass our technical call.

Engineers there shape what gets built, not only how, and work directly with product people.

What matters most to us
• You have built a product that people use every day, and you can point to the parts you owned
• You think about the person using the product. You question a feature when it does not serve them and suggest a better one
• Experience with creative, media or design products, or with shipping AI features to users, is a strong plus

What you will do
• Build and scale backend services in Go
• Run background jobs reliably, with queues, retries and idempotent steps
• Turn new capabilities into features people actually use
• Work with a cloud stack, message queues and APIs

You should have
• 3+ years of Go in production and 5+ years of backend work overall. If you come from a strong product team and work in another language, apply anyway and tell us how fast you would pick up Go
• Experience owning parts of a production system end to end
• Fluent English for daily work with the client team

The role is full time, 40 hours a week, long term, with a working day that overlaps European business hours. Individual engineers only, no agencies.

How we hire: a call with our CTO about your product work and your code, then a call with the client's team. Both are live, with screen share and without AI assistants.

To apply, open your application with a link to a product you helped build and one sentence on what you owned in it. Applications without it will not be read.

We’re looking for a User Acquisition Manager to own how new customers find Cloudfresh. Not one ad account. The whole engine. Running campaigns is part of it. The bigger job is deciding where the next qualified buyer comes from across channels, vendors and markets, and proving it in pipeline.

What You’ll Do

• Own paid acquisition end to end. Google Ads, LinkedIn, Meta and whatever channel earns its budget next.
• Reallocate budget every month across vendors, regions and channels based on CAC and pipeline. Cut what doesn’t pay back.
• Build and test landing pages, offers and retargeting flows. Grow conversion rates quarter over quarter.
• Run weekly tests on audiences, creatives, bidding and messaging. Keep a shared log of what worked.
• Set up tracking from ad click to closed deal in HubSpot. Report pipeline and revenue by campaign, not just leads.
• Drive registrations and pipeline for events, from webinars to our own events. Bring in real attendees who convert into deals, not just sign-ups.
• Use AI tools and agents to automate reporting, QA, competitor monitoring and campaign analysis.

• Agree on ICP, lead quality criteria and SLAs with marketing and sales teams. Review lead quality together every month.

   

What You Bring

• 3+ years in paid acquisition or growth, with B2B SaaS or tech experience
• Hands-on mastery of Google Ads and LinkedIn Ads. You’ve managed real budgets and can show results
• You think in pipeline and CAC, not CTR
• Strong analytics: GA4, Looker Studio or similar, plus AI tools to analyze data, spot patterns and build reports faster
• Experience with HubSpot or another CRM and marketing automation
• You’ve built and tested landing pages, not just briefed them
• You already use AI tools in your daily work and want to push further

• English at B2 or higher

   

Nice to have:

• Experience marketing cloud, security or IT products
• Multi-market campaigns across Europe, the Middle East or Central Asia
• Partner or channel marketing experience
• ABM tools and intent data

• Basic SQL or scripting for ads automation

   

Our Values

1. Customer First. Your success is our purpose.
2. Own the Outcome. We see it through.
3. Direct & Human. Honest, open and caring.
4. Raise the Bar. We never settle for “good enough”.

5. Generate the Real✨ Our DNA.

    

What We Offer

• Build your cloud marketing expertise with Google Cloud, Chrome Enterprise, Microsoft, HubSpot, Zendesk, Asana, Miro, GitLab, Okta, JumpCloud, Cloudflare and Wiz.
• Lead meaningful campaigns across EMEA, making an impact in diverse and dynamic markets.
• Bring your ideas to life in a culture that values creativity and is open to new approaches.
• Enjoy a competitive salary and a transparent bonus system tied to your results.
• Work flexibly remote or join us for a coffee in Kyiv or Prague offices.
• 24 vacation days, bank holidays, and 14 days sick leave.
• Medical insurance for team members in Ukraine.

We are the creators of a new fintech era!

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.
