Jobs at Djinni

Why we exist:

Swarmer develops software that makes drones autonomous and allows them to operate together, in large, coordinated teams — no pilots needed. Our technology has been battle-tested in Ukraine — the world’s most intense proving ground for drone warfare.

In March 2026, we became the first Ukrainian defense startup to go public on NASDAQ, following a $15M Series A — the largest investment in a Ukrainian defense tech company since the start of the war.

Working at Swarmer means operating at the intersection of engineering rigor and frontline reality. The problems and environments are complex, and the stakes are very real. We built this software to enable democratic nations to defend themselves.

If you are motivated by building resilient systems that matter and by seeing the direct impact of your work, you’ll find purpose here.

Who we’re looking for:

We’re looking for a Sales Manager to support our sales team in building strong, long-term relationships with customers and partners. In this role, you will coordinate the implementation of our software solutions in the defense technology sector and make sure customers, partners, and internal teams work together effectively.

This is a great role for someone who is proactive, relationship-driven, and comfortable working in a fast-paced, technically complex environment.

What you’ll do:

• Drive end-to-end sales efforts through active engagement with current clients and prospective partners.
• Identify defense expos, industry conferences, and global events, maintaining our strategic engagement schedule and partnering with our Global Communications Team.
• Serve as a representative at high-level meetings, field exhibitions, and defense summits alongside leadership.
• Draft compelling tailored pitch decks, technical proposals, and commercial collateral for potential partners and customers.
• Facilitate seamless cross-functional alignment between engineering specialists, product teams, and defense partners.
• Oversee active deployment timelines, ensuring clear communication channels and updates across all key stakeholders.
• Manage CRM data integrity, maintain detailed account records, and deliver precise commercial performance metrics.
• Execute ad-hoc operational priorities to accelerate business growth and advance our broader strategic goals.

What we need:

• 3-5 years of experience in Sales, Business Development, Account Management, or Customer Success.
• Advanced English (C1) or higher.
• A genuine interest in defense technology, UAVs, robotics, or other high-tech products.
• Strong communication and relationship-building skills.
• Excellent organizational skills, attention to detail, and the ability to manage multiple tasks simultaneously.
• Willingness to quickly learn technical aspects of the product and collaborate closely with the engineering team.

Would be an advantage:

• Experience working in the miltech or defense tech industry.
• Experience using CRM systems such as HubSpot, Salesforce, or similar.
• Basic understanding of the UAV market and defense technologies.
• Experience participating in tenders or working with government organizations.
• Experience representing a company at international exhibitions, conferences, or industry events.
• German, French, Polish, Baltic, Scandinavian, or other European language skills.

What you’ll get:

• Opportunity to build purpose-driven software that safeguards lives and advances defense technology.
• Fast-paced, high-stakes environment where your contributions yield immediate, tangible impact on the frontline.
• Agile, highly skilled team driven by engineering rigor and mission-critical goals.
• Attractive compensation package including 20 paid vacation days, comprehensive health insurance, and paid sick leave.
• Flexible working arrangements depending on operational and security requirements.

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 on a mission to build the next generation of poker learning, coaching, and training experiences.

This is not a traditional design role focused solely on visual polish or minor UI tweaks. We are looking for a Senior UX / Product Designer who deeply understands how poker players think, study, practice, and level up their game.

Your core task will be translating complex GTO strategies, solver data, and analytical workflows into intuitive, engaging, and highly effective product experiences. You will combine deep product thinking with real poker domain knowledge to help players bridge the gap between theory and execution at the tables.

If you love solving complex interaction challenges, simplifying heavy data systems, and designing products where skill mastery and progression truly matter — this role is for you.

What You’ll Do

• End-to-End Ownership: Lead the UX and product design strategy for our poker learning ecosystem — from initial conceptualization and research to prototyping, launch, and iteration.
• Translate Strategy into UX: Turn complex poker math, range analysis, and tactical concepts into frictionless, accessible product flows.
• Design Practice & Mastery Journeys: Create interactive drills, decision-tree simulations, hand history analysis workflows, and personalized coaching loops.
• Work with Experts & Players: Collaborate closely with professional poker players, coaches, and domain experts to uncover real study habits and pain points.
• Rapid Prototyping & AI Integration: Partner directly with product and engineering teams to prototype fast, leverage modern AI tools (Figma, Claude Code/Design), and test ideas iteratively.
• Data-Informed Design: Analyze user behavior and learning metrics to identify friction points, optimize retention, and improve learning outcomes.

• Establish UX Architecture: Build and scale design patterns, interaction standards, and UX frameworks for a growing suite of poker products.

   

What We’re Looking For

• Product Design Expertise: Proven track record of designing complex consumer-facing SaaS, EdTech, or data-rich digital products.
• Full-Stack UX Toolkit: Mastery of information architecture, user flows, rapid prototyping, wireframing, user research, and usability testing.
• Solid Poker Knowledge: Practical understanding of poker concepts, terminology, and how serious players study (GTO, ranges, equity, solvers, etc.).
• Tooling Proficiency: Deep hands-on experience with Figma and familiarity with Claude Code / Claude Design workflows.
• System Simplifier: Ability to take dense analytical data and reduce cognitive load without stripping away strategic depth.
• Product Mindset: Strong product judgment — you challenge assumptions, ask "why," and advocate for the user rather than just executing tickets.

• Communication & Collaboration: Excellent written and spoken English, with the ability to articulate design decisions to engineers and stakeholders clearly.

   

Nice to Have

• Hands-on experience designing poker software, solvers, training tools, or HUDs.
• Background in EdTech, competitive gaming, chess training platforms (e.g., Chess.com), or language learning apps (e.g., Duolingo).
• Experience with gamification, skill assessment models, and adaptive learning algorithms.
• Ability to contribute to high-fidelity UI and design systems when needed.

• Passion for using AI-assisted tools to speed up design exploration and research workflows.

   

What Success Looks Like

Success in this role isn’t just about making the interface look sleek. Success means helping players learn faster, practice more effectively, understand their leaks, stay engaged, and measurably improve their win rates.

You will set the product foundation that keeps our experiences intuitive, structured, and genuinely empowering as our platform grows in complexity.
