Jobs at Djinni

We're looking for a Lead QA Engineer to own quality across a mobile feed product spanning iOS, Android, and a Go backend. You'll sit in the release path for every feature, bug fix, and A/B variant, making sure nothing ships without being rigorously tested first. This is a hands-on role: you'll be running test suites, managing CI/CD and release tooling, and reading code yourself to understand what actually changed, not just working from a spec. The environment moves fast, so you'll also need to be comfortable smoke-testing incident fixes quickly to unblock releases without cutting corners on safety. You'll work across the full stack, verifying tracking events and A/B test variants on the mobile side while also testing backend behavior in Go. This is a role for someone who wants deep, end-to-end ownership of quality inside a startup that ships constantly.

Details:
Schedule: Full time
Location: Sofia, Bulgaria (Onsite, 5 days a week)
Start: ASAP
Duration: Long-term
English: Fluent

About the project:
The company is building a mobile app with a TikTok-style feed of short, AI-generated browser games created by users. It's an early-stage startup moving at a rapid release cadence, shipping features, bug fixes, and A/B test variants continuously rather than on long cycles. Quality currently rests on how thoroughly each release is tested before it goes out, which is why this role is being built out as a dedicated, owned function rather than something spread thin across the team. The product spans a full stack: mobile clients on iOS and Android, and a Go backend behind them, so testing has to cover both the client experience and the systems underneath it. Because the product runs on experimentation, verifying tracking events and A/B variants correctly is a core part of keeping releases trustworthy. The team is small and fast-moving, so this role carries direct ownership of the release path rather than slotting into an established QA process.

You have:
- Professional QA experience covering both mobile apps (iOS and Android) and backend systems
- Hands-on experience running test suites and working with CI/CD, bug tracking, and analytics tooling — not manual testing alone
- The ability to read and understand code to verify changes, even without writing features yourself
- Ideally, experience QA-ing feature-flagged or A/B-tested mobile products
- Ideally, familiarity with Go or broader backend testing experience
- Ideally, experience with mobile release tooling such as TestFlight or Play Console internal tracks
- Ideally, a background in startups, hyper-casual gaming, or other fast-release-cadence environments
- Willingness to work full-time, strictly on-site in Sofia, Bulgaria

What to do:
- Own quality end-to-end across iOS, Android, and the Go backend
- Run test suites and manage CI/CD and release tooling ahead of every release
- Read and review code changes to understand what shipped and verify it behaves as expected
- Smoke-test incident fixes rapidly to unblock releases while balancing speed with safety
- Verify tracking events and A/B test variants are behaving correctly on mobile
- Build out and improve QA process and tooling as the release cadence and product surface grow

NuxGame is a B2B iGaming technology provider. We deliver turnkey casino and sportsbook platforms, game aggregation, and sweepstakes products to operators worldwide, across four product lines: Turnkey Traditional, Sweepstakes Turnkey, Game Aggregation, and Sweepstakes Game Aggregation. Our customers are operators. Their back office teams work in our platform every day, and their players use it every time they deposit, verify their identity, or withdraw.
We are looking for a Product Manager to join our team.

What we expect from the candidate:

• You own the roadmap for your domains and you defend it. Prioritisation is your call to make and to explain, not something you escalate by default.
• You write specifications that an engineer can build from without a business analyst in between: scope and non scope, flows, edge cases, dependencies, acceptance criteria.
• You work with data yourself. You define the metric, pull the number, and check it before you act on it.
• You go deep on the technical side. You read API documentation, review integration contracts, and hold your own in a discussion with engineers.
• You design for many operators at once. Every decision is a decision about configuration, defaults, and backward compatibility, not about a single customer.
• You close the loop after release. A feature that shipped and moved nothing is not a delivered feature.

Requirements

Must have

• 5+ years in product management, with at least 3 years owning payments, fraud and risk, or financial products in iGaming, fintech, or payments.
• Hands on experience with PSP and payment aggregator integrations: REST APIs, request and response construction, webhooks and callbacks, idempotency, status and error mapping, reconciliation.
• Practical understanding of the trade offs between hosted payment pages, iframe, and fully platform hosted cashier flows, including where PCI scope, conversion, and support load land in each.
• Experience with several payment method families: cards, e-wallets, bank transfer and local rails, vouchers, and crypto (networks, confirmations, on ramp providers).
• Experience integrating KYC and AML providers, and owning or building a rule based fraud or risk engine.
• Experience with rule based configuration and player segmentation: defining segments, resolving conflicts between overlapping rules, and giving business users a safe way to change them without a release.
• Working knowledge of the regulatory requirements affecting deposits, withdrawals, KYC, and responsible gambling in at least two or three jurisdictions.
• Data fluency: deposit success rate, approval rate by provider and method, withdrawal processing time, chargeback rate, verification funnel conversion. You can pull these yourself.
• B2B product experience. Our users are operators and their back office staff, not only end players.

• Structured written communication in English. Russian or Ukrainian for internal team communication.

   

Nice to have

• Experience in a multi tenant white label platform serving dozens of operators at once.
• Sweepstakes or social casino experience, where purchase and redemption flows differ from classic deposit and withdrawal.
• Experience with payment orchestration platforms, smart routing, and cascading.
• Experience with Metabase or a comparable BI stack, and enough SQL to validate a number.
• Practical use of AI tooling in the product workflow for discovery, documentation, and analysis.

Your position will include:

Payments and PSP

• Own the payment roadmap across all four product lines and decide what gets built, what gets configured, and what gets refused.
• Own the internal payment gateway as a product: integration contract, provider onboarding, error handling and retries, logs, and the tooling support uses to investigate a stuck transaction.
• Own the technical and product side of PSP relationships and work with our PSP Manager, who owns commercial terms and provider selection.
• Drive deposit and withdrawal conversion: cashier UX, method visibility and ordering, error minimisation, hosted versus platform side flows, retry and cascading logic.
• Own crypto and Web3 coverage: networks, confirmations, on ramp providers, wallet based authorisation and deposits.

• Shorten the time it takes to launch a new provider by standardising the integration, so a new PSP becomes configuration rather than custom development.

   

Fraud, KYC and compliance

• Own the fraud and risk engine: rules and thresholds, risk scoring, verification flows, duplicate account and bonus abuse detection, manual review load.
• Own third party KYC and AML integrations end to end, from provider evaluation and platform requirements through rollout to operators.
• Turn licensing and jurisdictional requirements into configurable platform capability instead of per operator custom work.

• Hold the balance between fraud prevention and conversion, and defend where you put the threshold.

   

Auth and identity

• Own registration and login as a conversion product, including social and Web3 registration.
• Own the relationship between authentication and verification: what a player can do before KYC, what unlocks after it, and how that differs by jurisdiction and by operator.

• Own back office authentication, permissions, and audit logs as an operator facing product.

   

Segmentation

• Own segmentation as a shared service: how segments are defined, evaluated, and consumed across payments, limits, verification, and reporting.
• Make it usable by operators without engineering involvement: rule builder, preview and validation before a segment goes live, predictable behaviour when several segments match one player.

• Own the cost side of it: evaluation performance on large player bases and what happens when a segment changes mid-session.

   

Reporting, limits and responsible gambling

• Own operator facing financial reporting, dashboards, and export tooling.
• Own the limit framework (deposit, loss, wager, session) and geo blocking as jurisdiction aware, operator configurable capability.
• Own the responsible gambling toolset and make sure it satisfies the licences our operators hold.

What we offer

Full ownership of a product area that directly moves revenue for dozens of operators, with a dedicated engineering team behind it.

A direct line to the CPO and to top management. Decisions here take days, not quarters.

We believe that a happy team builds the best products. Here is how we support you:

• Remote & Flexible: Work from anywhere. Our core hours are 09:00/10:00 to 17:00/18:00 (Kyiv time), Mon-Fri.
• Financial Stability: Timely payment for compensation for services
• Personal Equipment Policy: equipment are provided for use to ensure comfortable and efficient work.
• Knowledge Sharing: We regularly gather to discuss new trends, share insights, and elevate one another.
• Community: At NuxGame, you will work in a team of like-minded people who are ready to support, inspire, and tackle complex challenges together.
• Creative Freedom: We encourage initiative. With us, you have the freedom of professional expression and the space to implement your ideas.
• Time-off Policy: 24 vacation days per year + 5 sick days (without medical confirmation).

• Atmosphere: A friendly environment focused on results and mutual respect, free from unnecessary bureaucracy and pressure.

   

We believe in unlocking the inner potential of each team member within an open and democratic culture.

Waiting for you on our team!

ABOUT OUR 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 Software Engineer for the connectivity stack of a large-scale data platform. The work spans three areas:

• Client connectivity — drivers and client libraries used by applications and BI tools
• Source connectivity — connectors to databases and data systems, including authentication, metadata discovery, and query/data pushdown, with certification and upgrade support
• Agent & service connectivity — tool interfaces and integrations for AI-agent access to the platform

Deep expertise in one of these areas is enough — you'll grow into the adjacent ones over time. This is a role for an engineer who cares about API and protocol stability, backward compatibility, and interoperability with the tools enterprises actually use. You will lead the design and delivery of substantial components, working within an established architecture alongside US-based engineering reviewers.

This is a systems-level, backend engineering role focused on drivers, protocols, and distributed services — not application development or CRUD services.

RESPONSIBILITIES

• Lead the design and delivery of connectivity components — client drivers, source connectors, and service integrations — turning ambiguous initiatives into well-scoped, reviewable milestones
• Produce technical designs, explain architectural trade-offs, and surface compatibility, security, and delivery risks early
• Maintain backward compatibility and API/protocol stability; build compatibility, interoperability, and performance test suites
• Develop and maintain connectors for major BI tools, collaborating with the technology partners behind them
• Diagnose complex client/server, protocol, and distributed-system failures; drive root-cause analysis of customer-reported and escaped defects
• Improve diagnostics, logging, observability, and supportability of the connectivity stack
• Contribute upstream to open-source projects (e.g., Apache Arrow) where agreed
• Mentor engineers, participate in code and design reviews, and communicate progress and risks clearly across a distributed team

REQUIRED QUALIFICATIONS

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 8+ years of production software engineering experience
• Deep proficiency in Java or C++, and the ability to work effectively in another systems/services language
• Experience designing and debugging APIs, protocols, client libraries, or distributed services

• A track record of comprehensive testing — unit, integration, compatibility, and performance
• Experience with production CI/CD, release processes, and engineering quality controls
• Working knowledge of SQL
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• Clear written and verbal communication in a distributed engineering environment; English Upper-Intermediate or higher (B2+)
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

DESIRED SKILLS

• JDBC, ODBC, ADBC, or database-driver development experience
• Apache Arrow (including Arrow Flight)
• SQL engines, databases, or data platforms
• Source-connector development for databases, warehouses, or SaaS systems
• MCP or agent-tool integrations
• OAuth, OIDC, TLS, and enterprise authentication flows
• Cross-platform native build, packaging, and release experience
• BI-tool interoperability (Power BI, Tableau) and partner collaboration
• Observability and production diagnostics
• Open-source contribution experience

DETAILS

About Our 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 Software Engineer to build and operate production AI agent and search services on top of a large-scale data platform. This is hands-on work at the intersection of distributed backend engineering and applied AI: multi-agent workflows, tool-execution infrastructure, retrieval and relevance, and integrations with multiple LLM providers — all running as real, customer-facing production services with the reliability expectations that implies.

Responsibilities

• Design and implement scalable multi-agent workflows (including conversation state), tool-execution infrastructure, and data-aware tools working with catalogs, schemas, lineage, SQL, jobs, semantic metadata, data preparation, and visualizations
• Build search and retrieval capabilities with OpenSearch or equivalent — indexing, relevance tuning, hybrid keyword + vector search
• Integrate multiple LLM/model providers with secure configuration and graceful degradation
• Develop APIs and event contracts across REST, streaming/SSE, gRPC, protobuf, and SDKs, including UI integrations
• Operate, monitor, and improve production services — service health, logs, metrics, traces, search-cluster health, latency, and error rates; participate in the team's production-support model
• Investigate incidents, drive root-cause analysis, and ship durable fixes
• Design for permissions, tool approvals, multi-tenancy, and customer-data governance
• Maintain dependencies, apply security fixes, and reduce tech debt; produce designs, tests, runbooks, and documentation; lead technical discussions and review code

Required Qualifications

• B.S. or M.S. in Computer Science, Computer Engineering, or a related field — or equivalent practical experience
• 7+ years of relevant experience, or equivalent demonstrated senior-level impact
• Strong Java software engineering skills
• Strong grasp of concurrency, data structures, API design, testing, maintainability, and backward compatibility
• Solid background in distributed systems, microservices, cloud services, or data-intensive backends
• Hands-on experience with search technologies — OpenSearch, Elasticsearch, or Lucene — including vector search, embeddings, or relevance systems
• Experience building LLM applications, agent/tool workflows, RAG systems, or model-provider integrations
• Strong production instincts: diagnosing failures via logs, metrics, and traces; designing for fault tolerance, retries, cancellation, and recovery
• SQL and familiarity with data platform concepts: catalogs, metadata, schemas, governance, lineage
• Comfort leading ambiguous, cross-service work with clear stakeholder communication and strong written documentation
• Comfortable with AI-assisted development workflows — using modern AI tools productively while critically validating their output
• English Upper-Intermediate or higher (B2+) — daily written and verbal communication with a US-based engineering team
• Availability to work EU business hours shifted 2–3 hours later for daily overlap with US West Coast mornings

Desired Skills

• LangChain4j or similar agent frameworks
• Python for AI services, evaluation harnesses, or sandboxed execution
• React and TypeScript
• gRPC, protobuf, Quarkus, Kubernetes, MongoDB, KV stores, event-driven architectures
• Apache Arrow, Apache Iceberg, OpenLineage, semantic layers, or data-governance systems
• AI quality evaluation: LLM-as-judge, model benchmarking, production AI metrics
• OpenSearch operations: index lifecycle management, relevance tuning, incident response
• Open-source contributions

We’re looking for a hands-on SEO Content Marketing Manager to help grow AndonPulse through high-intent content, organic search, and content distribution.

AndonPulse is a B2B SaaS product for engineering leaders. We help engineering teams understand delivery performance, forecast initiatives, identify bottlenecks, analyze engineering costs, and make better decisions based on their development data.

This is not a pure copywriting role. We’re looking for someone who can identify content opportunities, prioritize them based on business value and search intent, create strong content, publish it, and analyze what works.

The initial focus will be on bottom- and middle-of-the-funnel content such as comparison pages, alternative pages, "best tools" articles, use-case pages, and educational content around engineering management.

What you'll do

• Research keywords, competitors, search intent, and content opportunities.
• Build and maintain a prioritized content roadmap.
• Create BOFU content such as:
  • "[Product] alternatives"
  • "AndonPulse vs [competitor]"
  • "Best tools for [use case]"
  • software/category pages
  • use-case and solution pages
• Create educational content around engineering management, delivery, engineering analytics, forecasting, engineering costs, and related topics.
• Interview the founder or other subject-matter experts to turn domain knowledge into useful content.
• Write, edit, optimize, and publish content in English.
• Optimize existing pages and articles based on search performance.
• Improve internal linking, on-page SEO, titles, descriptions, and page structure.
• Use Google Search Console, GA4, Ahrefs/Semrush or similar tools to understand performance.
• Track rankings, qualified organic traffic, conversions, and other relevant metrics.
• Experiment with content distribution through relevant communities, directories, LinkedIn, Reddit, and other channels where appropriate.
• Help with occasional product launches and campaigns, such as Product Hunt.
• Explore SEO, GEO/AEO and visibility in AI search tools such as ChatGPT, Perplexity, and Google AI results.

What we're looking for

• 2+ years of experience in SEO, content marketing, or organic growth.
• Experience working with B2B SaaS or another complex B2B product.
• Strong written English. You should be able to produce publication-ready content for a US/EU audience.
• Hands-on experience with keyword research and search-intent analysis.
• Understanding of SEO fundamentals and how content contributes to acquisition rather than just traffic.
• Experience creating or optimizing commercial / BOFU content.
• Ability to research unfamiliar technical or business topics.
• Ability to work independently: identify opportunities, propose priorities, and execute them.
• Comfortable using AI tools as part of the content workflow while maintaining factual accuracy and strong editorial quality.

Nice to have

• Experience marketing products for developers, engineering teams, CTOs, or technical B2B audiences.
• Experience with SaaS comparison and alternative pages.
• Experience with conversion optimization.
• Experience with link building, digital PR, or partnerships.
• Experience with GEO / AEO / AI-search optimization.
• Experience launching products on Product Hunt or similar platforms.

What success looks like

We don’t measure success by the number of articles published.

We care about:

• growth in relevant search visibility;
• rankings for commercially relevant searches;
• qualified organic traffic;
• visibility in AI search and answer engines;
• conversions from organic/content traffic;
• content that influences signups, demos, or pipeline.

Format

• Part-time: approximately 15–20 hours per week.
• Fully remote.
• Long-term cooperation if there is a good fit.
• Flexible working hours.
