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’re looking for a Payment Manager to own payment operations across our international markets — monitoring performance, resolving issues, and keeping payment flows running at the level our players expect.

The ideal candidate understands acquiring and payment processing in depth, has hands-on experience with Tier-1 markets, and can move fast when something goes wrong. In this role, you will proactively identify root causes and coordinate resolutions independently, without waiting to be told what to do.

💳 What you’ll be doing

Issue Resolution & Investigation

• Analyse and resolve payment issues: failed, declined, pending, and unsuccessful transactions.
• Investigate transaction cases and identify the root causes of payment failures.
• Handle chargebacks, payment disputes, refunds, and reversals.

Provider Coordination & Communication

• Communicate and coordinate directly with PSPs, acquirers, payment providers, and internal teams to drive fast resolutions.
• Escalate critical payment issues and seamlessly coordinate resolution with relevant stakeholders.

Monitoring & Analytics

• Monitor the performance, availability, and stability of all payment methods.
• Track conversion rates, decline rates, and transaction success rates — quickly identifying anomalies and acting on them.
• Analyse payment reports to identify recurring errors, technical issues, and unusual transaction patterns.

Process Optimisation & Reporting

• Maintain accurate payment reporting and comprehensive documentation.
• Actively participate in improving payment flows, operational processes, and overall payment performance.

🎯 What we’re looking for

• 2+ years of experience in Payments, Payment Operations, Payment Support, or a similar role.
• Market expertise: Proven experience working with Tier-1 markets and international payment flows.
• Payment processing knowledge: Strong understanding of acquiring processes, transaction flows, and the roles of PSPs, acquirers, issuers, and payment methods.
• Hands-on provider experience: Practical experience working with PSPs, acquirers, payment gateways, and payment aggregators.
• Technical depth: Deep knowledge of payment failure reasons, transaction statuses, declines, refunds, reversals, and chargebacks.
• Analytical skills: Proven experience monitoring and analysing payment performance and conversion metrics, with the ability to identify root causes quickly.
• Autonomy & focus: The ability to work independently, make fast decisions in a dynamic environment, manage multiple tasks simultaneously, and prioritise effectively.
• Stakeholder management: Strong communication skills and absolute confidence when dealing with external payment providers.
• Language skills: English Intermediate or higher.

✨ What we offer

• Fully remote setup.
• Direct influence on payment performance and infrastructure across international markets.
• Fast decision cycles and absolutely no bureaucracy — when you spot an issue, you own the resolution.
• Cross-functional collaboration with the Product, Risk, Antifraud, and Support teams.
• Paid vacation and sick days.
