Jobs at Djinni

About the Role

We are looking for a QA Automation Engineer who can go beyond standard test automation and apply AI to improve and scale QA processes.

This is a hands-on role where you will own QA from scratch and build automation that reduces manual effort — including leveraging LLMs in real workflows.

You will be the sole QA engineer, working closely with developers on an AI-powered product.

What You’ll Do

• Build and maintain test automation infrastructure from scratch
• Own the full QA process (automation + manual where needed)
• Improve product stability and reliability together with the engineering team
• Design automation that reduces repetitive QA work
• Apply AI tools and LLMs to testing workflows (not just usage, but integration)
• Contribute to testing AI-driven features

Requirements

• 5+ years in QA Automation
• 3+ years of hands-on experience with Python
• Strong experience building automation frameworks from scratch
• Experience with Playwright
• Experience with GitHub
• Ability to work independently and take full ownership

AI Automation Experience (Required)

We are specifically looking for hands-on experience applying AI in real workflows, not just using coding assistants.

Examples of relevant experience:

• Integrating LLM APIs (OpenAI, Claude, etc.) into automation pipelines
• Generating test cases or test data using AI
• Analyzing logs, test results, or failures with LLMs
• Building scripts or tools where AI helps make decisions or reduce manual QA work

Important:
Using tools like Copilot, Cursor, or ChatGPT as assistants is not sufficient.

Nice to Have

• Experience testing AI / LLM-based products
• Understanding of frontend frameworks
• Experience with TypeScript
• Startup experience

Why This Role

• High ownership: you will build QA processes from scratch
• Direct impact on product quality and engineering workflows
• Opportunity to work with AI-driven systems in practice, not theory
• Small team, fast decisions, real influence

Interview Process

• 30 min intro
• Test task
• Short video explanation of your solution
• 2 hands-on technical interviews

Five years ago, this job needed a team of four: an analytics engineer, a BI developer, a data analyst, and a stats specialist. Today, with the right platform and the right AI tooling, one sharp person can do all of it — faster. We've built the platform. We need that person.

Bright Gaming is an online casino founded in 2023 by iGaming veterans. Growing fast, fully remote, lean by design — no legacy debt, no committees.

The role

You'll own our analytics platform end-to-end and use it to drive better decisions across marketing, product and CRM. Two hats:

• 🔧 Builder — Extend our SQL-first warehouse, cohort/revenue/player-value models, BI layer and AI tooling. New questions arrive every week; you build the answers.

• 🎯 Operator — Sit close to marketing, product and CRM. Find where the levers are, pull them, then check whether they moved. You'll be measured on whether those teams ship better decisions because of you.

   

Reports to founder.

What you'll own

• KPI reporting for leadership and department heads
• Marketing analytics: ROAS, acquisition cost, Fraud traffic
• Product & CRM analytics: funnel, A/B tests, segmentation, lifecycle, churn, bonus ROI
• Player analytics: cohort retention, LTV, VIP and churn signals
• Reconciliation against payment, game-provider and partner reports

• Extending the data layer as new business questions arrive

   

Who you are

A technical analyst who thinks like a commercial operator. As comfortable refactoring a 300-line SQL query as sitting in a marketing standup arguing about creative spend. You don't wait to be asked questions — you go find them. And you've figured out that AI tooling is a force multiplier, not a threat.

Must-have:

• 3+ years as a Data Analyst, Analytics Engineer or Product Analyst in iGaming
• Advanced SQL on PostgreSQL — window functions, CTEs, query optimisation. 
• Python for analysis, automation and third-party APIs (pandas, requests).
• BI tooling (PowerBI, Metabase, Looker or similar)
• Git — branches, PRs, code review. Everything lives in version control here.
• Fluent with AI tooling. You use Claude / ChatGPT / Copilot every day, prompt them well, and know when not to trust the output.
• Strong grasp of iGaming metrics: GGR/NGR, FTD, LTV, ROAS, retention cohorts, churn
• Commercial instinct — you can brief a non-technical exec without jargon

• B2 English or higher

   

Strong plus:

• Statistical fundamentals 
• dbt or similar transformation framework
• REST API integration experience
• Experience embedded with marketing or CRM teams (not just serving tickets)

What we offer

• Fully remote, flexible hours, performance bonuses
• Real ownership — you'll be the data person, not the seventh analyst
• Modern stack, zero legacy, no 15-year-old reports
• Direct line to leadership
• The chance to prove the full-stack, AI-augmented analyst is the future of data teams

1. Review & edit AI-generated articles

   • You make sure every article feels useful, specific, and non-generic for that audience.

• You can keep the author’s voice while making the content sharper and more professional.

• You can communicate clearly and politely with customers in English (both written and spoken).
• You’re reliable: if you set a deadline, you hit it.

Nice-to-haves (not mandatory, but helpful):

• Experience with B2B SaaS or technical content

How we work

• Fully remote, async-friendly

• Senior peers & advisors - work alongside PhDs who've worked with NASA, Google, Microsoft, Bosch and more.
• Fast growth - startup scaling revenue and product lines quarter-over-quarter.
• Remote autonomy & flexible hours - we care about output, not chair time.

If you're excited to push the boundaries of AI Search Engine Visibility and Optimization, and want to help shape the future of marketing technology, we want to hear from you!
