Jobs at Djinni

Mailkeeper. It is a SaaS solution designed to improve user retention and increase overall product revenue through email marketing, push notifications, and PWA channels. 

Mailkeeper team integrates directly into products and provides a full cycle of email processes – from developing email strategies and testing hypotheses to optimizing email logic and managing sender reputation using its own email marketing service.

You will:

• Lead a portfolio of external partners: their email metrics and revenue are your numbers, and you decide what to do with them;
• Find growth points in the data yourself, form hypotheses, run A/B tests and experiments, and bring the ones that work to production;
• Decide what each partner needs next: which campaigns, segments, or integrations to push, and drive those decisions with partners and our internal team;
• Catch problems before partners do: track sending volumes, deliverability, and revenue, and act on anomalies the same day.
• Ship technical changes end to end: from a partner's request to a specced task, a release, and a verified result;
• Build the direction's processes and documentation so that onboarding a new partner is repeatable, not heroic.

We'll have a match if you:

• 1+ year in a commercial B2C product company as PM / PO / Growth / CRM / Retention manager, with a metric you personally owned and can show as "from A to B"
• Proactivity: you generate your own hypotheses and push things forward without waiting to be asked;
• Analytical mindset: you form the question yourself, go to the data, and build decisions on numbers;
• Strong communication skills: you can run partner communication independently and drive discussions to decisions;
• AI: you have built something repeatable with AI (an agent, automation, or pipeline), not just used chat tools;
• Basic technical literacy: you understand what an API is and can speak the same language as developers;
• English: Upper Intermediate.

Will be an advantage:

• Experience with email marketing / retention channels.
• Understanding of email deliverability (SPF/DKIM/DMARC, sender reputation).
• Experience with Jira and sprint-based development processes.

About us
Next Dialog automates business communication with AI. Our omnichannel platform handles customer conversations across phone, SMS and messaging: answering questions, booking appointments, qualifying leads and syncing everything to the CRM, 24/7. Our clients range from HVAC installers and real estate brokerages to dental clinics, logistics and energy companies across Poland, Germany, the rest of Europe and the US. We're a small, product-focused team working at the intersection of AI and communication automation, and we're hiring a Forward Deployed AI Engineer to own our AI systems from architecture to live production.

The role
You own AI systems end to end, from architecture to live production. You will:

• Build harnesses: test and eval harnesses for LLM and voice pipelines, simulated conversations, and regression suites that catch quality drops before clients see them
• Instrument what ships: tracing of LLM and agent calls (prompts, tool calls, tokens, cost, latency), quality monitoring and regression alerts in production
• Design and build microservices: new services and integrations that fit into a platform running in production, including MCP servers and tools for our agents and internal tooling
• Optimize AI pipelines: latency, cost, accuracy, and reliability, measured with real metrics
• Automate everything repetitive: checks, deployments, agent setup, and routine ops, using scripts, agents, and MCP tooling
• Design for safety and privacy: prompt injection, PII handling, call-recording consent, human approval for irreversible actions
• Own live production: monitor, debug, and fix real campaigns running real calls

What the role is not

• Not a research role. No model training from scratch, no TensorFlow/PyTorch.
• Not a prompt-only role. Prompts are one tool among evals, tracing, integrations and ops.
• Not a frontend role. React/Next.js is in the stack, but it is not where you will spend your days.

Our stack
TypeScript, NestJS, PostgreSQL, React, Next.js · Retell AI, LiveKit, Deepgram, ElevenLabs, Twilio · Gemini/Vertex AI, OpenAI, Anthropic · Langfuse / OpenTelemetry-style tracing · GCP, Terraform, Docker · Cursor, Claude Code, MCP

Must have

• 4+ years of engineering experience in any server-side language, with a strong track record of designing, running and supporting microservice architectures in live production
• Production experience with LLMs: prompting, structured output, tool calling, RAG, evals
• Experience building test or eval harnesses and automating pipelines
• Experience with LLM observability: tracing prompts, tool calls, tokens, cost and latency, and using traces to find and fix regressions
• AI-native workflow: you do most of your tasks through AI agents and know how to build context for them
• Hands-on experience with MCP: you have built or wired MCP servers and tools, not only used them
• Strong SQL: comfortable analysing call and campaign data in PostgreSQL
• Experience with real-time or webhook-driven systems
• You design for safety and privacy: prompt injection, PII, consent, guardrails
• English B2+

Nice to have

• Voice AI experience (Retell, Vapi, LiveKit, Pipecat, telephony, SIP/WebRTC, streaming audio, STT/TTS, turn-taking and interruptions, latency tuning)
• Past experience as a team or tech lead
• Forward deployed or solutions engineering experience at a startup
• GCP, Terraform, on-prem deployments

We are currently looking for a CRM / Retention Manager who knows that sending the same bonuses to the same users on repeat isn't a strategy — it's just activity without results. We need someone who can build smart automated campaigns, understand bonus economics, experiment with gamification, and turn bold ideas into measurable business outcomes.

If you know how to keep players engaged, bring inactive users back, and make every campaign serve a clear business goal, we want to hear from you. 🚀

• Develop and implement gamification mechanics to drive player engagement and retention.
• Plan, launch, and analyze A/B tests for communications, offers, bonuses, gamification mechanics, and automated CRM flows.
• Monitor campaign performance and optimize activities based on business KPIs, including retention, NGR, bonus rate, ARPPU, and unsubscribe rate.
• Identify the root causes of declining player activity and develop hypotheses to prevent churn and reactivate users.
• Take ownership of new ideas from hypothesis development and validation to implementation, testing, and optimization.
• Make quick HTML edits to CRM templates and ensure campaigns display correctly across channels.

• Collaborate with Product, Design, Analytics, and Content teams to deliver effective CRM initiatives.

   

✅ Requirements

• Proven experience in CRM, Retention, or Lifecycle Marketing, preferably within iGaming.
• Strong understanding of the iGaming customer lifecycle and retention strategies.
• Experience designing and managing automated CRM campaigns and customer journeys.
• Hands-on experience with audience segmentation and personalized communications.
• Understanding of CRM channels, including Email, Push Notifications, SMS, and In-app messaging.
• Experience with retention and reactivation mechanics, promotional offers, and bonus campaigns.
• Understanding of bonus economics and the ability to evaluate campaign effectiveness from a business perspective.

• Strong analytical skills and the ability to translate campaign results into actionable improvements.
• Understanding of key metrics such as LTV, churn rate, retention rate, reactivation rate, ARPPU, NGR, and bonus rate.
• Experience working with HTML and making edits to email templates.

🎁 What We Offer

💰 Competitive salary

🌍 Full remote work — work from wherever you're most productive.

🚀 Freedom to experiment, test bold hypotheses, and make decisions without unnecessary bureaucracy.

🎯 Real ownership of CRM strategy, campaigns, and retention performance.

🛠️ The opportunity to work with a full range of CRM channels, automation tools, and gamification mechanics.

📊 A data-driven environment where campaign success is measured by business impact, not just the number of messages sent.

🤝 A collaborative team that values initiative, fresh ideas, and people who take ownership of their results.

😎 A friendly team where work doesn't run away — but the wolf might just be out for a walk.

— Are uncomfortable making progress when the initial information is incomplete.
— Wait to be asked before sharing updates, risks or available capacity.

We are looking for a talented Product Designer with strong wireframing skills and the ability to structure complex product logic into clear, usable experiences. This role is particularly suited for someone who enjoys working with data-heavy, multi-layered SaaS platforms and translating complexity into intuitive interaction models. 

The designer will work in close collaboration with senior designers, Product, and Engineering as part of a shared design process, contributing to solution development, refining user flows, and ensuring consistency across the product. The role is not limited to execution - it requires analytical thinking, ownership of UX structure, and active participation in shaping scalable solutions. 

Key Requirements  

• Strong experience in wireframing, interaction design, and information architecture 
• Proven ability to work with complex, data-heavy SaaS systems or applications 
• Preferably experience in B2B products, where workflows and operational logic are critical 
• Ability to translate ambiguous or technical requirements into structured UX solutions 
• Comfortable working within an established design framework while contributing improvements 
• Strong collaboration skills across Product, Design, and Engineering 
• Detail-oriented with a focus on usability, clarity, and scalability rather than purely visual output 
• Working hours 10 am - 6 pm CET time (11 am - 7pm Kyiv), Mon-Fri

Collaboration & Contribution 

This role contributes to the team by supporting and strengthening the overall design delivery - developing wireframes, validating structural decisions, and helping scale consistent patterns across the product ecosystem. The designer will partner with senior team members to ensure alignment, while bringing their own expertise and problem-solving approach to day-to-day work. 

Focus Areas 

• Structuring complex features into clear user flows and layouts 
• Supporting redesign and product evolution initiatives 
• Ensuring UX consistency across modules and touchpoints 
• Contributing to the development and application of the design system 
• Helping translate business and technical needs into usable product experiences

• Develop and maintain internal tools, business automation solutions, dashboards, and CRM systems.
• Build user interfaces using React and develop backend services with Node.js.
• Design database structures and write queries for PostgreSQL and MongoDB.
• Integrate third-party APIs and implement AI workflows using the OpenAI API and AI-assisted tools like Cursor.
• Participate in basic DevOps and deployment activities (Git, GitHub, deployment platforms).

• Collaborate with experienced developers, receive mentorship, and gradually take ownership of end-to-end features.

   

Requirements

Must-have:

• Fundamental knowledge of JavaScript and core web development principles (frontend & backend basics).
• Strong motivation to learn fast, adapt, and grow professionally.
• Desire to build a long-term career in Full Stack Development.

Will be a plus:

• Experience with React or Node.js (pet projects, coursework, or self-study).
• Practical understanding of REST APIs and database concepts.
• Familiarity with Git and GitHub.

Not required:

• Commercial software development experience.
• Fluent / perfect English.

• Full mastery of the entire tech stack from day one.
