Jobs at Djinni

About the role:

No legacy, no bureaucracy, no corporate b**t — just you and a small but incredibly strong engineering team making the right technical decisions together.

This is payment infrastructure, so the bar for reliability, security, and operational excellence is high. You won't just "keep the lights on" — you'll help design, build, and evolve the platform.

AI-first. We're AI-first across the board, engineering included: routine operational work is automated through AI agents and AI tooling, IaC and runbooks are written and maintained with AI. We're not just "aware of AI" — we're building infrastructure that AI agents can safely operate and change.
 

What you'll do:

• Infrastructure as Code: Design and evolve Terraform modules for AWS (composite modules, accounts as code), and build a multi-environment foundation across non-prod / pre-prod / prod.
• Kubernetes: Operate and evolve EKS clusters — workloads, namespaces, resources, autoscaling, and network policies.
• CI/CD: Build, maintain, and improve GitHub Actions pipelines — faster, more reliable delivery with fewer manual steps.
• GitOps / Delivery: Manage Helm charts and ArgoCD for declarative Kubernetes deployments.
• Secrets & Access: Own secrets management, rotation, least-privilege access, and keep secrets out of code.
• Observability: Build metrics, dashboards, and alerting (Amazon Managed Prometheus + Amazon Managed Grafana), define SLOs, and improve incident response.
• Security & Networking: Manage IAM, environment separation, and secure access with Okta and Twingate.
• Databases (Operations): Operate PostgreSQL (RDS) and Redshift — configuration, backups, secret rotation, and operational reliability.
• Reliability: Drive production readiness, capacity planning, cost optimization, HA where it matters, and operational runbooks.
   

Stack:

• Cloud: AWS (EKS, RDS, IAM, VPC, etc.)
• IaC: Terraform
• Containers: Docker, Kubernetes (EKS), Helm
• GitOps: ArgoCD
• CI/CD: GitHub Actions
• Observability: Amazon Managed Prometheus (AMP), Amazon Managed Grafana (AMG)
• Database: PostgreSQL (RDS), AWS Redshift (OLAP)
• Auth / Access: Okta, Twingate
• AI: AI-first — active use of AI tools and AI agents in daily engineering work.
   

Requirements:

Must have

• 5+ years in DevOps, SRE, or Platform Engineering.
• Production AWS experience (EKS, IAM, VPC, RDS).
• Terraform — modules, remote state, multi-environment infrastructure.
• Kubernetes — production operations, Helm.
• CI/CD — building, maintaining, and improving pipelines.
• Linux, networking, scripting (Bash + Python or Go).
• Secrets management and security fundamentals (IAM, least privilege).
• Observability — metrics, logs, and alerting (Prometheus/Grafana or equivalent).
• AI fluency — actively uses AI tools (Claude Code, Cursor, Codex, or similar) in day-to-day engineering work. Not just "aware of AI" — uses them to multiply productivity while applying engineering judgment to the output.
• Proactivity — identifies problems before they surface, proposes solutions, and drives them to completion. Doesn't wait to be told what to do.
• English: confident reading and listening is a must. Good spoken English is a strong plus.
   

Nice to have

• FinTech, payments, or banking infrastructure experience.
• Experience building toward or maintaining PCI DSS compliance.
• ArgoCD / GitOps.
• Amazon Managed Prometheus / Grafana.
• AWS Redshift.
• Multi-account AWS environments with clear non-prod / pre-prod / prod separation.

If you want to develop, initiative and result oriented, our company is waiting for your resume.

About the role: We are looking for a Senior Business Development Manager  who will become a true "trusted advisor" and strategic partner for our key clients. This is not just a support role — it is a position that directly impacts the operators' business growth and the company's revenue.

What you will do:

• End-to-end B2B partner lifecycle management: from successful onboarding and integration to scaling and contract renewals.
• Relationship management: build and maintain long-term relationships with C-level executives and key stakeholders on the operator side.
• Portfolio management: conduct regular Health Checks, hold Quarterly Business Reviews (QBRs), and proactively drive Churn Prevention.

Our expectations (Requirements):

• Experience: Mandatory, proven experience in Account Management within the iGaming industry.
• Background: Ideally, experience managing White Label projects from the B2B platform side. Experience working on the side of an iGaming operator (understanding the pain points and needs of a B2C business).
• Seniority: Senior level. Proven ability to handle demanding B2B clients, confidently manage escalations, and lead complex commercial negotiations.
• Languages: Fluent in English and Russian.
• Location & Mobility: Remote, but you must have the ability and necessary travel documents (e.g., a valid visa/passport) for travel to EU countries for client meetings and industry conferences.

We're hiring a Senior Affiliate Lead to take full ownership of our affiliate direction. Two mandates: first, fix what we have; second, turn it into a network. Our products are SaaS — building a network on top of them is the logical next step, and you're the one who does it.

This isn't partner management. It's ownership of a channel end-to-end.

🔥 What You'll Do

Task #1 — Audit & fix the current program. Take everything we run today and put it in order: offers, creatives, partners, payout system. Find why we're not scaling and ship a clear fix.

Task #2 — Build the network. Convert the program into a full affiliate network from the ground up: structure, onboarding, offer distribution, economics.

Ongoing:

• Offers & funnels — rework existing offers and sales funnels to market demand; brief creative on high-converting banners, landers, and promo assets.
• Partnerships — onboard top-tier partners (direct affiliates, webmasters, networks); build long-term win-win relationships, not transactions.
• Traffic & economics — own traffic quality and fraud control; optimize across CPA / RevShare / CPS against CPA, ROI, LTV.

• Testing — new GEOs, sources, and partner-acquisition angles.

   

✅ What We're Looking For

• 4+ years in affiliate marketing, with hands-on experience in both an affiliate program and an affiliate network.
• Proven track record building, restructuring, or scaling affiliate programs or networks.
• Must-have: existing network of affiliate contacts (direct or network deals) and immediate access to scalable traffic.
• Ownership — you treat the channel as your own business, not a task list.
• Funnel expertise — read conversion data, spot offer weaknesses, write clear design/copy briefs.
• Data-driven problem solver — see the business bottleneck behind the numbers.
• Strong negotiation — pitch offers to top partners, close exclusive terms.

• English B2+ (negotiations and business correspondence).

   

🎯 KPIs

• Network growth — high-quality traffic volume and active affiliate base.
• ROI & unit economics — profitability and margins.
• CRO — conversion at every funnel step (click → lead → deposit / purchase).
• Partner retention & LTV.

💰 Compensation: competitive base + aggressive bonus tied to partner onboarding, offer performance, and total traffic profit.

🌍 What We Offer

• Full ownership & autonomy — your direction, zero micromanagement.
• Fast team — quick decisions, full resource support (budgets, design, dev).
• Remote-first — flexible hours and location.
• Benefits — paid vacation, sick leave, health insurance.
• Culture — real work-life balance, mutual respect, ownership, genuine passion for the results.

We're hiring a hands-on PPC Lead to take full ownership of our paid acquisition. Emphasis on hands-on: you're in the accounts yourself — auditing, diagnosing, and buying media with your own hands — not managing people who do it for you.

We're in an active rebuild of the channel, so we need an operator, not an overseer: someone who spots what's underperforming without being asked, ships the fix, scales what works, and sees the next strategic move before it's obvious. You'll work shoulder-to-shoulder with our analysts and own the direction end-to-end.

🔥 What You'll Do

• Own the accounts, hands-on. Personally audit and run buying across Google Ads and Meta first, then Bing, TikTok, Pinterest, and other networks as needed. You're in the accounts daily, not reading dashboards about them.
• Find problems before we ask. Spot what's broken or leaking, call it out, and ship the fix — without waiting for direction.
• Scale what works. Take winning campaigns from hand-bought to scaled, across channels and budgets.
• Launch new products. Build acquisition engines for new tech products from scratch while scaling the core B2C offerings.
• Co-own the data. Work directly with our analysts on raw data and the full user journey — write precise briefs for BI/data engineering (attribution, cohorts, custom conversions, server-side/CAPI) and use the output to drive real decisions.
• Decide on real economics. Go past in-platform metrics — LTV, CAC, ROAS, cohort retention, true margin.
• Test systematically. New channels, placements, bidding, audiences, landers, creative concepts.
• Brief creative. Partner with design and copy on high-converting video/visual assets for TikTok, Meta, Pinterest.

• Own the budget. Allocate and scale six-figure monthly spend for profit, not vanity reach.

   

✅ What We're Looking For

• 5+ years hands-on PPC / performance marketing, proven in B2C tech.
• Actually hands-on. You buy media yourself, live in the accounts, and can walk into any account and diagnose it fast. Not someone who delegates and reports up.
• Owns the direction. You build initiatives independently — no step-by-step guidance, no waiting to be assigned a problem.
• Sees their own mistakes. Intellectual honesty over polish. You name what's not working — yours included — and fix it. No corporate talk.
• Direct experience managing and scaling budgets of $200,000+/month with strong ROI/ROAS. (set to your real number)
• Multi-platform depth: Google Ads, Meta, Bing, SA360, TikTok, Pinterest (programmatic/DSP a plus).
• Raw-data mastery: works with raw data directly (SQL / BigQuery / Snowflake a strong advantage) and writes clear technical specs for analytics teams.
• Strong B2C product sense: funnel optimization, subscriptions, app installs, or D2C digital products.

• English B2+ (fluent written and spoken).

   

🎯 KPIs

• CAC & ROAS — sustainable acquisition cost while scaling return on spend.
• LTV / margin — scalable, profitable traffic with high long-term value.
• Channel diversification — scaling TikTok, Meta, Networks, etc.

• New launches — acquisition executed for new products from zero.

   

🌍 What We Offer

• Full ownership & impact — complete autonomy over strategy, budget, and channels.
• Tech-first, growth environment — high-potential products and new launches.
• High-calibre team — direct work with product, data engineers, and creative.
• Remote-first — flexible, trust and results over micromanagement.
• Competitive comp & benefits — salary, performance bonuses, paid vacation, sick leave, health insurance.
