Jobs at Djinni

About us

UAPP.AI is a product company. We build AI-powered mobile applications used by over 10 million people. The full product cycle stays in-house — from the idea to scale and monetization. Decisions are fast and data-driven, without bureaucracy.
 

The Role

We run a subscription product across mobile and web. Payments go direct, through our own provider stack — Stripe, Unlimit, Payable, Traspay, SolidGate, Checkout.com, ADN, Apple.

We are looking for a Head of Payments to strengthen the payments direction: onboarding new providers and products, domain compliance, fees, reconciliation and approval rate on rebills.

The role is hands-on: you work alongside the team, not only assign tasks.
 

What you will do

• Provider onboarding: new PSPs, plus new products with providers we already work with — applications via agents, merchant ID registration, entities
• Domain compliance: preparing the websites we submit for onboarding to meet provider requirements — knowing what has to be stated, how and where (terms, refund and subscription cancellation policy, pricing, product description, contacts, support) and keeping it current after underwriting
• Recurring and rebills: retry logic, soft/hard declines, payment-method update flows, reducing involuntary churn
• Approval rate: audit by GEO, provider and card scheme, routing and cascading priorities
• Commercial terms: negotiating fees and rolling reserves, auditing commissions to see where the money leaks
• Reconciliation and reporting: settlement reconciliation, payment reporting, cost transparency per product and provider
• Analytics: your own dashboards on payment metrics, built with AI tools
   

What we expect

• 4+ years in payments, at least 2 at Head / Lead level
• A portfolio of several PSPs: Stripe, SolidGate, Checkout.com, Unlimit and similar
• Merchant onboarding: applications, merchant IDs, underwriting
• Understanding of provider compliance requirements for websites: what has to be stated and where
• Recurring payments: rebills, decline handling, churn caused by failed payments
• Approval-rate and fee optimization — with numbers behind it
• Willingness to work hands-on and use AI tools daily
• English B2+
   

Nice to have

• Mobile subscriptions, IAP, web-to-app funnels
• Negotiating enterprise terms with Tier-1 providers
   

What we offer

• Fully remote, full-time
• A working stack and a team already running the direction — you join a live process
• Fast decisions without long approval chains
• A product with 10M+ users and a growing subscription business — the result of your work shows on the revenue chart
• Competitive USD-pegged compensation, reviewed on results

About Lexidesk
 

Lexidesk is an AI intake platform for US law firms. Our AI agent answers calls and messages from potential clients 24/7, qualifies them, and books them into the firm's calendar, so lawyers stop losing clients to voicemail. 

We're a small, fast-moving team building on the latest AI tooling, and our customers are real law firms that rely on us to talk to their clients.
 

You'll be our first dedicated support hire, working directly with the founder.
 

What you'll do
 

Keep customers running
 

• Own the Intercom inbox: resolve tickets and follow through until the customer is actually unblocked.
• Take phone support calls from US and UK law firms.
• Handle technical implementation: connect firms' phone systems, calendars, and CRMs to Lexidesk via integrations, webhooks and API settings.
   

Make support smarter
 

• Build and maintain our Help Center.
• Train and improve the Intercom AI support bot so it answers most questions before a human is needed.
• Design Intercom automations and propose how support can be faster, more self-serve and better for customers.
   

Grow accounts
 

• Proactively check on customers who haven't reached out. Catch problems before they become churn.
• Spot where a firm would benefit from a feature they aren't using yet, and suggest it.
• Ask happy customers for reviews and testimonials.
   

What we're looking for
 

• English at B2+ or better. You'll be writing to and speaking with native speakers daily.
• You already know what an API request and a webhook are, and you are interested in AI.
• You can explain technical things to a non-technical lawyer without jargon, and without losing patience on the third try.
• You like customers. You want a long-term role in support/customer success.
• Available Mon–Fri 13:00–21:00 Kyiv time, and not currently studying.
• Bonus: experience with Intercom, help centers, telephony/VoIP, or a US-facing SaaS.
• Bonus 2: experience with legal/legatech industry.
  
   

What we offer
 

• $1000–$1,500/month base depending on experience.
• Performance bonuses tied to customer reviews and account growth. Top performers meaningfully out-earn the base.
• Paid AI tools (Claude and others). You'll use them daily.

• Engineering experience: 3+ years in backend/systems software engineering.
• CI/CD & DevOps basics: Practical experience with Jenkins pipelines and modern development workflows.
• Containers: Working knowledge of Docker and basic Kubernetes (running workloads, debugging pods, kubectl fluency).
• Cloud: Comfortable operating in at least one major cloud (GCP, AWS, or Azure).
• Version Control: Confident with Git / GitHub workflows.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.

DESIRED SKILLS

• Experience with Apache Arrow (columnar in-memory format).
• Familiarity with Apache Calcite (SQL parsing, planning, optimization framework).
• Exposure to Gandiva or LLVM-based expression compilation.
• Experience with open table formats — Apache Iceberg, Delta Lake, or Hudi.
• Familiarity with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines(e.g., Presto, Trino, or similar).
• Understanding of query planning, optimization, and execution internals.
• Experience with data connectivity drivers: JDBC, ODBC, Arrow Flight.
• Kubernetes on managed services (GKE / EKS / AKS) and multi-cloud exposure.
• IaC tools such as Terraform.
• Experience with performance profiling and optimization of latency-sensitive systems.
• Please note: We can consider only candidates currently residing in the EU, EEA, or the UK.

• Version Control: Confident with Git / GitHub workflows and rigorous code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, leading technical designs, or owning components end-to-end.

ABOUT THE CLIENT

Our client is a leading enterprise data platform company building an open, high-performance data lakehouse for AI and analytical workloads. The platform combines an intelligent SQL query engine, an AI-ready semantic layer, and an open catalog built on Apache Iceberg — enabling Fortune 500 companies across finance, energy, manufacturing, and logistics to unify, query, and govern data at massive scale across cloud and on-premise sources.

ABOUT THE ROLE

We are looking for a Senior SDET to lead the design of automated test frameworks and testing strategy for a large-scale distributed data platform. You will own the quality of the query engine, connectivity layer, and backend services end-to-end — from framework architecture through CI/CD infrastructure across all major clouds — and mentor middle engineers on the team.

This is a data-heavy, backend-focused role. We are not looking for web/UI QA engineers — the work centers on validating distributed query execution, data correctness at scale, connectivity drivers, and backend microservices.

RESPONSIBILITIES

• Architect, design, and evolve automated test frameworks in Python / pytest for backend services, REST APIs, and distributed data components.
• Define testing strategy for new features and platform components — coverage, risk assessment, and quality gates.
• Own end-to-end, integration, performance, and regression testing covering SQL query execution, data correctness at scale, and platform APIs.
• Lead performance and load testing efforts with JMeter, including workloads over JDBC / ODBC / Arrow Flightdrivers.
• Design and validate large-scale data testing scenarios — query plans, result correctness across heterogeneous data sources, metadata consistency, and behavior under high concurrency.
• Own CI/CD test pipelines in Jenkins — architect, maintain, and continuously improve.
• Provision and manage test environments in Kubernetes (GKE / EKS / AKS) across GCP, AWS, and Azure using Docker; drive automation and reproducibility.
• Investigate complex, cross-layer failures and drive root-cause analysis with engineering.
• Mentor middle SDETs, review test designs, and set quality standards across the team.
• Partner with US-based development leads on shift-left practices, testability, and release readiness.

REQUIRED QUALIFICATIONS

• Education: B.S. or M.S. in Computer Science, Computer Engineering, or a related technical field.
• Programming: Strong proficiency in Python, including pytest, with deep understanding of OOP, software design principles, and test framework architecture.
• SQL & Data: Advanced SQL skills and strong understanding of relational and analytical data systems, including query execution internals.
• Data-intensive testing experience: Demonstrated experience testing data-intensive systems — query engines, ETL/ELT pipelines, streaming platforms, or analytical databases. Candidates with only web/UI QA backgrounds are not a fit.
• Testing experience: 5+ years in backend/system test automation, with demonstrated ownership of test strategy and infrastructure.
• CI/CD & DevOps: Solid experience architecting and maintaining Jenkins pipelines and test environments.
• Containers & Orchestration: Strong working knowledge of Docker and Kubernetes (running workloads, debugging pods, deploying complex environments).
• Cloud: Hands-on experience with at least one major cloud (GCP, AWS, or Azure); exposure to more than one is a strong plus.
• Version Control: Confident with Git / GitHub workflows and code review practices.
• English: Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team.
• Availability: Able to work EU hours with a 2–3 hour shift toward US West Coast time to ensure daily overlap with the client team.
• Leadership: Prior experience mentoring engineers, defining test strategy, or leading a QA/SDET function.

DESIRED SKILLS

• Deep experience testing REST APIs and backend microservices at scale.
• Hands-on with distributed computing frameworks (e.g., Apache Spark, Kafka) and MPP SQL query engines(e.g., Presto, Trino, or similar).

About Us 

We're hiring on behalf of our partner — a company that powers the operations behind regulated and high-risk industries. 

They give fast-moving businesses in these spaces the structure, compliance and talent they need to scale — without slowing down.

About the Role

We're looking for a T-shaped marketer — someone with deep expertise in one or two core marketing disciplines, paired with broad working knowledge across the full marketing and growth stack. This isn't a role for someone who wants to execute a checklist. We need someone who can think strategically, execute hands-on, lead a small team, and open doors with clients and partners.

You'll own marketing strategy end-to-end, manage and grow our marketing function, and act as a bridge between marketing and revenue — engaging directly with clients and prospective partners. This is a high-ownership role for someone who wants to build something real, not just "run campaigns."

Who You Are

• Proactive by default. You spot problems and opportunities before being asked to look for them.
• Hungry to build. You think in systems and roadmaps, not one-off tasks.
• High ownership. You treat this like your own business — because in many ways, it will be.
• Results-driven within a real structure. Core working hours are 10:00–19:00 CEST, and we expect you to be present and available during that window for meetings, collaboration, and client/partner calls. Within that structure, we don't micromanage how you spend your time — we care about the quality of your thinking and the results you deliver, not how busy you look.
•  Eager to learn and adapt. You pick up new tools, channels, and skills fast, and you're comfortable being a beginner when needed.
• T-shaped. You have real depth in at least one area (e.g., performance marketing, content/brand, product marketing, or lifecycle/CRM) — and enough breadth to be genuinely useful — not an expert, but capable of jumping in and getting things done — across the rest (SEO, paid, content, social, email, analytics, positioning).
• Commercially minded. You understand that marketing exists to drive pipeline and revenue, not just impressions.

What You'll Own

🎯 Marketing Strategy

• Define and drive the overall marketing strategy aligned with business goals
• Identify the highest-leverage channels and initiatives — and kill the ones that don't work
• Set KPIs, own the marketing roadmap, and report on results (not activity)
• Continuously test, learn, and iterate across positioning, messaging, and channels

👥 Team Leadership

• Manage and mentor the existing marketer(s), setting clear priorities and growth paths
• Identify gaps in the team and make the case for new hires as the function scales
• Build lightweight processes that keep the team moving fast without unnecessary bureaucracy

🤝 Business Development & Partnerships

• Engage directly with prospective clients — you're comfortable on sales calls and think like a seller, not just a marketer
• Identify, pitch, and close new partnership opportunities (co-marketing, channel, affiliate, or strategic)
• Act as a face of the company in external conversations — confident, credible, and commercially sharp

🛠️ Hands-On Execution

• Roll up your sleeves when needed — whether that's writing copy, reviewing a campaign, or jumping into a client call
• Ensure marketing output (content, campaigns, brand) is consistently high quality and on-strategy

What Success Looks Like

• Marketing has a clear strategy tied directly to pipeline/revenue goals
• The marketing team operates with clarity, autonomy, and increasing capability
• New partnerships and client relationships are actively contributing to growth
• Leadership trusts you to make the right calls without needing to check in constantly

Ideal Background (guidelines, not gatekeeping)

• 4+ years in marketing with progressively increasing scope/ownership
• Experience managing at least one direct report, or informally leading projects/teams
• Some exposure to sales, partnerships, or client-facing work — even informally
• A portfolio of things you've built, launched, or grown — not just "supported"
• Comfortable with ambiguity and early-stage/startup environments

How We Work

• Outcomes over hours. We measure impact, not time logged.
• High trust, high accountability. You'll get autonomy fast — and we expect you to earn and keep it.
• Flat structure. You'll work directly with leadership, not through layers of approval.

Ready to own marketing — not just run it?
If you're a builder who thrives on ambiguity, ownership, and results, we want to hear from you. Apply now and tell us about something you built, launched, or scaled from scratch.
