Jobs at Djinni

We are looking for a Smart Contract Auditor to join our security team. You will audit DeFi protocols, identify critical vulnerabilities, and work directly with development teams to secure their code before deployment. This is not a "run Slither and generate a report" role—we need someone who thinks like an attacker, understands EVM internals, and can deliver clear, actionable findings. 

What You'll Do

• Conduct full-scope audits of Solidity smart contracts, including manual line-by-line review, automated scanning (Slither, Mythril), and fuzz testing (Foundry/Echidna)
• Identify and exploit vulnerabilities such as reentrancy, oracle manipulation, access control flaws, economic attacks, and governance risks
• Write Foundry-based Proofs of Concept (PoCs) demonstrating each critical finding with reproducible test cases
• Produce detailed audit reports with clear severity classifications, exploit paths, and specific remediation recommendations
• Collaborate with client dev teams during the remediation phase—explain findings, review fixes, and ensure vulnerabilities are properly addressed
• Stay current with emerging attack vectors, EIPs, and DeFi primitives

What We're Looking For

Must-Have:

• 2+ years of experience in smart contract auditing or blockchain security engineering
• Expert-level Solidity and deep understanding of the EVM (storage layout, opcodes, gas mechanics, proxy patterns)
• Strong Foundry/Forge skills—you write fuzz tests and invariants as part of your audit workflow
• DeFi domain expertise—lending protocols, AMMs, liquid staking, governance modules, tokenomics
• Ability to write clear, concise reports that explain technical risks to both engineers and non-technical stakeholders
• Upper-Intermediate English or higher—you'll communicate directly with international clients

Nice-to-Have:

• Experience with formal verification (Certora, Halmos)
• Track record on public audit contest platforms (Code4rena, Sherlock)
• Knowledge of Rust/Cairo for non-EVM chains
• CTF experience (Ethernaut, Damn Vulnerable DeFi)

What We Offer

• Competitive salary (discussed privately) + performance bonuses for critical findings
• Fully remote—work from anywhere within Ukraine or EU timezone
• Flexible working hours—focus on results, not clock-watching
• Professional development—budget for conferences, courses, certifications
• Work on cutting-edge protocols—you'll see code before it hits mainnet
• No micromanagement—you own your audit process from start to finish

How to Apply

Please submit:

1. Your CV and/or LinkedIn profile + Github account
2. Links to public audit reports, Code4rena/Sherlock profile, or bug bounty findings (anonymized if under NDA)

Evotime Films is a video production company. We make commercials and brand films for US clients, including Fortune 500 brands. We combine traditional shoot production with AI pipelines, which lets us deliver at a speed and price that normally does not exist in this market.
 

Our portfolio is ahead of our marketing presence. We are hiring one person to close that gap and own it.

What you will own:
 

• Instagram, two pages, US market and Ukrainian market
• LinkedIn, company page plus the founder’s personal profile
• Paid campaigns on Meta and LinkedIn, from structure to targeting to creative briefs to reporting
• Content system. We produce commercials constantly. Every project should become 8 to 10 pieces of content, and you decide what those are
• Website conversion. Pages, meta descriptions, contact flow, landing pages for campaigns
• Briefing our designer and our video team on the assets you need
   

What we expect in the first 90 days:
 

• A written plan with numbers you commit to
• Consistent publishing across all channels, not in bursts
• Paid campaigns running with a clear cost per result
• Measurable growth in reach and engagement from our actual audience, US marketing and brand decision makers
• Inbound conversations starting to appear
   

Requirements:
 

• Hands on experience managing Meta ad budgets. You will be asked how much, on what, and what the results were
• LinkedIn experience, organic and paid
• Written English strong enough that a US marketing director reads your copy and does not notice it was not written by a native speaker. This is the single most important requirement
• Ukrainian for internal communication
• Evidence. Accounts you grew, campaigns you ran, numbers before and after
   

Who this is not for: strategists who write plans and hand them off, specialists who only do one channel, anyone who needs to be told what to do each week.
 

We are a small team. You will have a budget, a designer, a video production team, and direct access to the founders. What you will not have is someone standing over you.
 

Compensation: 2,000 to 3,000 USD per month depending on experience. Remote, full-time, with working hours that overlap the US morning at least partially.
 

How we hire: application screening, a 30 minute call, then a paid test task for two to three finalists. We pay for the test because we respect your time.
 

To apply, send your CV and answer three questions:

1. What monthly ad budget have you personally managed, on which platforms, and over what period?
2. Links to two accounts or campaigns you grew, with numbers before and after.
3. Look at our Instagram and LinkedIn. In five to seven sentences, in English, tell us the first thing you would change and why.

Applications without answers to all three questions will not be reviewed.

Evotime Films — це video продакшн-компанія. Ми знімаємо рекламу та бренд-фільми для американських клієнтів, серед яких бренди зі списку Fortune 500. Ми поєднуємо класичний продакшн з AI-пайплайнами, і це дає швидкість та ціну, яких на цьому ринку зазвичай не існує.

Наше портфоліо сильніше за нашу маркетингову присутність. Ми шукаємо одну людину, яка закриє цей розрив і візьме його на себе повністю.
 

За що ви відповідатимете:
 

• Instagram, дві сторінки, ринок США та український ринок
• LinkedIn, сторінка компанії плюс особистий профіль засновника
• Платні кампанії в Meta та LinkedIn, від структури й таргетингу до брифів на креативи та звітності
• Контентна система. Ми постійно випускаємо рекламні ролики. Кожен проєкт має перетворюватись на 8 або 10 одиниць контенту, і що саме це буде, вирішуєте ви
• Конверсія сайту. Сторінки, мета описи, форма контакту, лендінги під кампанії
• Брифи для нашого дизайнера та відео команди на потрібні вам матеріали
   

Що ми очікуємо за перші 90 днів:
 

• Письмовий план з цифрами, за які ви відповідаєте
• Стабільні публікації в усіх каналах, а не ривками
• Запущені платні кампанії зі зрозумілою вартістю результату
• Вимірюване зростання охоплення та залучення саме нашої аудиторії, а це маркетинг та бренд менеджери у США
• Перші вхідні звернення
   

Вимоги:
 

• Практичний досвід управління рекламними бюджетами в Meta. Ми спитаємо скільки, на що і з якими результатами
• Досвід у LinkedIn, органіка та платне просування
• Письмова англійська такого рівня, щоб маркетинг-директор у США читав ваш текст і не помічав, що його писала людина, для якої англійська не рідна. Це найважливіша вимога
• Українська для внутрішньої комунікації
• Докази. Акаунти, які ви виростили, кампанії, які ви вели, цифри до і після
   

Кому ця робота не підійде: стратегам, які пишуть плани і передають їх іншим, спеціалістам одного каналу, і тим, кому щотижня треба казати, що робити.
 

Ми маленька команда. У вас буде бюджет, дизайнер, відеопродакшн і прямий доступ до засновників. Чого у вас не буде, так це людини, яка стоїть над душею.
 

Компенсація: від 2 000 до 3 000 USD на місяць залежно від досвіду. Віддалено, повна зайнятість, з частковим перетином робочих годин з ранком у США.
 

Як ми наймаємо: скринінг заявок, дзвінок на 30 хвилин, далі оплачуване тестове завдання для двох або трьох фіналістів. Ми платимо за тестове, бо поважаємо ваш час.
 

Щоб податись, надішліть CV і дайте відповіді на три питання:
 

1. Яким місячним рекламним бюджетом ви особисто керували, на яких платформах і протягом якого періоду?
2. Посилання на два акаунти чи кампанії, які ви виростили, з цифрами до і після.
3. Подивіться на наші Instagram і LinkedIn. У п’яти або семи реченнях, англійською, напишіть, що б ви змінили в першу чергу і чому.

Заявки без відповідей на всі три питання не розглядатимуться.

We're looking for a Middle+ Data/Databricks Engineer to join our data team and take ownership of pipelines built on Databricks. You'll design and run production-grade ETL/ELT workloads, work with the lakehouse (Delta Lake) architecture, and partner closely with analysts, data scientists, and business stakeholders who rely on the data you deliver. "Middle+" here means roughly 3–5 years of hands-on data engineering experience: you can own a pipeline end to end with minimal supervision, make sound design decisions, and are starting to mentor more junior engineers — without yet carrying full architectural ownership of the platform.

Contract & Logistics

• Contract type: B2B (valid Czech IČO / trade license required).
• Location: Remote, candidate must be based in the Czech Republic; occasional visit to Prague office.
• Start date: ASAP
• English: Fluent 
• Czech: Native/Fluent 

What You'll Do

• Design, build, and maintain scalable ETL/ELT pipelines on Databricks using PySpark and SQL.
• Implement and evolve Delta Lake tables following a medallion (bronze/silver/gold) architecture.
• Develop batch and, where needed, streaming data processing jobs (Structured Streaming).
• Build and maintain CI/CD for Databricks notebooks and jobs (Databricks Asset Bundles, Repos, Git-based workflows).
• Orchestrate pipelines with Databricks Workflows, Azure Data Factory, Airflow, or similar tools.
• Monitor job performance and cluster costs; troubleshoot failures and optimize for reliability and spend.
• Implement data quality checks, testing, and monitoring for critical datasets.
• Collaborate with analysts, data scientists, and business stakeholders to translate requirements into data models.
• Participate in code reviews, document technical decisions, and help shape engineering best practices.
• Provide guidance and informal mentorship to junior team members.

What We're Looking For

• 3+ years of hands-on experience with Apache Spark, ideally on Databricks specifically.
• Strong PySpark and SQL skills, including performance tuning of Spark jobs.
• Practical experience with Delta Lake and lakehouse architecture concepts.
• Solid grasp of data modeling (dimensional modeling, star schema) and ETL/ELT design patterns.
• Experience with at least one major cloud platform — Azure, AWS, or GCP (Azure Databricks is a plus).
• Familiarity with pipeline orchestration tools (Databricks Workflows, ADF, Airflow, or equivalent).
• Working knowledge of Git and CI/CD practices for data engineering.
• Understanding of data governance, access control, and security basics (Unity Catalog is a plus).
• Good written and spoken English; Czech or Slovak is a plus but not required.
• Comfortable working independently and communicating clearly in a remote, distributed team.

Nice to Have

• Databricks certification (Data Engineer Associate or Professional).
• Experience with streaming technologies such as Kafka or Azure Event Hubs.
• Experience with dbt for transformation and testing.
• Solid Python software-engineering practices — testing, packaging, typing.
• Infrastructure-as-code experience (Terraform).
• Exposure to MLOps or ML pipeline support.
• Experience in a regulated or large enterprise data environment.

What We Offer

• Fully remote work with flexible hours, based anywhere in the Czech Republic.
• Long-term B2B cooperation with a stable pipeline of work.
• A modern, actively evolving data stack rather than legacy maintenance work.
• Direct collaboration with senior engineers and architects — real input on design decisions.
• Budget for training, certifications, and conference attendance.
• A flat structure with fast decision-making and minimal bureaucracy.

About Yanarchy

Yanarchy is a Los Angeles–based talent management agency working with media creators and digital talents as scalable businesses.

We combine content, growth systems, audience development, and technology to build sustainable creator businesses and long-term monetization models.

Our content team works with international audiences, with a strong focus on Tier-1 markets and English-speaking audiences.

The Role

We are looking for an AI Content Researcher to help our creative team identify relevant trends, formats, references, and content opportunities for our talents.

In this role you will analyze what works, why it works, and how a successful concept can be adapted to our talents and recreated with AI.

You will work closely with AI Content Creators, turning research into clear, actionable references that can be directly used in production.

This role is a strong fit for someone with a background in SMM, Content Management, Community Management, or Junior Creative Marketing who naturally follows social media trends, understands audience behavior, and wants to develop deeper expertise in AI-powered content production.

What You Will Do

Trend & Content Research

• Monitor Instagram, TikTok, Facebook, YouTube Shorts, and other relevant platforms for emerging trends and high-performing content.
• Identify content formats, visual concepts, hooks, narratives, and creative mechanics relevant to our talents.
• Focus primarily on Tier-1 markets, especially the US.
• Track emerging formats before they become mainstream and identify opportunities for adaptation.
• Follow creators, media pages, AI creators, and trend-focused accounts to stay ahead of new content directions.

Content Analysis

• Analyze why specific content performs well or fails.
• Break down successful videos into key elements: hook, visual concept, pacing, narrative, format, sound, and audience trigger.
• Understand how platform algorithms and audience behavior influence content distribution.
• Evaluate references from a viral potential and adaptation perspective, rather than simply looking at view counts.
• Identify which elements can realistically be recreated or adapted for our talents.

Reference Development

• Build structured daily collections of relevant video references.
• Prepare approximately 30 video references per working day based on current priorities.
• Adapt research to the specific talent, audience, niche, and content direction.
• Add context and hypotheses to references so that the AI Content Creator understands what should be recreated and why.
• Clearly communicate the key idea, mechanics, and expected result of each reference.

AI Content Research

• Maintain a working understanding of current AI content-generation tools and their capabilities.
• Research which AI models and tools are best suited for specific creative tasks.
• Understand the differences between tools such as Seedance, Kling, Nano Banana, and other emerging AI solutions.
• Identify which tools can work from video references, which are primarily image-based, and which are better suited for static or motion content.
• Follow AI creators and industry experts to identify new tools, workflows, and creative possibilities.
• Continuously expand your understanding of how AI can be used to reproduce or transform successful content concepts.

Collaboration with AI Content Creators

• Turn research into clear production-ready briefs.
• Communicate the key creative idea, reference, desired outcome, and important execution details.
• Discuss feasibility with AI Content Creators and adjust references when necessary.
• Collect feedback on what works technically and use it to improve future research.
• Build a repeatable research → hypothesis → production feedback loop.

What We're Looking For

• 1+ year of experience in SMM, Content Management, Community Management, Junior Creative Marketing, or a similar role.
• Strong understanding of Instagram, TikTok, Facebook, and short-form content mechanics.
• Genuine interest in social media trends and digital content.
• Ability to recognize patterns behind successful content rather than simply copying what is popular.
• Understanding of audience psychology and what makes people stop scrolling, watch, share, comment, or return.
• Strong visual and content intuition.
• Ability to work specifically with US / Tier-1 audience references.
• Strong research and information-filtering skills — you can quickly separate useful references from noise.
• Ability to structure large amounts of information clearly and turn it into actionable recommendations.
• English level sufficient for researching and understanding English-language content and communicating within the team.
• Basic understanding of AI content-generation tools and their capabilities.

We are not looking for an AI tools expert. You don't need to have deep hands-on experience with every generation platform. What matters more is your ability to understand what a tool can do, quickly learn new solutions, and connect AI capabilities with content ideas.

Nice to Have

• Previous experience with AI-generated content.
• Experience working with creator, media, or subscription-based products.
• Experience targeting US or other Tier-1 markets.
• Experience with organic content growth.
• Familiarity with AI video and image generation tools.
• Experience creating content briefs or creative references for editors, designers, or creators.
• Personal interest in AI, emerging technologies, and digital media.

What Success Looks Like

After the first few months, you should be able to:

• Consistently identify relevant and actionable content opportunities.
• Provide a reliable flow of high-quality references for the AI Content team.
• Explain why a reference works and how it can be adapted.
• Identify trends relevant to specific talents and audiences rather than following trends blindly.
• Build increasingly accurate hypotheses about what can generate organic reach.
• Help the team discover new AI tools and production possibilities.
• Turn research into content that demonstrates strong viral potential.

What We Offer

• Fully remote work in an international team.
• Opportunity to work at the intersection of social media, content, AI, and creator economy.
• Direct collaboration with creative and AI content teams.
• Exposure to Tier-1 markets and US-focused content strategies.
• Fast-moving environment with a high level of ownership.
• Opportunity to develop into a Creative Strategist / AI Content Strategist role.
• Paid vacation, sick leave, and personal days off.
