Jobs at Djinni

About Us
We are Folqs, a fast-growing direct-to-consumer supplement brand specializing in premium health and wellness products across the United States. We heavily leverage high-converting Direct Response (DR) mechanics, running cold traffic through custom VSLs, long-form landing pages, and advertorial funnels to scale rapidly.

Role Overview
We are looking for an experienced Direct Response Media Buyer to take full ownership of scaling our YouTube and native acquisition channels alongside Google Ads. You will work closely with our team to test angles, optimize funnels, and scale profitable ad spend.
This is not a traditional Search-and-Shopping-only PPC role. YouTube is a primary growth engine for us, and Native (Taboola, Outbrain, Revcontent) is our secondary pillar. If you specialize in cold-traffic DR funnels, VSL testing, advertorial-to-checkout flows, and aggressive scaling, this is built for you.

WHAT YOU'LL DO
 

• Own YouTube at scale: Build, manage, and scale cold-traffic YouTube campaigns—optimizing campaign structure, placement strategy, creative hooks, and view-through vs. click attribution.
• Scale native funnels: Plan, launch, and optimize native campaigns across Taboola, Outbrain, and Revcontent - managing publisher bids, blocklists, headline/thumbnail testing, and advertorial alignment.
• Manage full-funnel Google Ads: Build and optimize Google campaigns across Search, Shopping, Performance Max, Display, and Demand Gen, maintaining strict brand defense and retargeting logic.
• Optimize Merchant Center & tracking: Oversee Google Merchant Center feeds, policy compliance, and server-side/conversion tracking setups (GTM, GA4, and multi-touch attribution tools).
• Collaborate on creative strategy: Brief and collaborate with copywriters and video editors on fresh VSL concepts, native headlines, visual hooks, and advertorial angles.
• Test & analyze continuously: Execute systematic A/B tests across ad copy, video angles, bidding strategies, and landing page flows. Monitor CAC, ROAS, and overall spend efficiency daily.
   

REQUIREMENTS
 

• 3+ years of hands-on media buying experience in eCommerce / Direct Response (DTC background preferred).
• Proven track record managing $50k+/month in profitable ad spend.
• Deep YouTube Ads expertise: Demonstrable experience driving cold traffic on YouTube at scale using VSLs and long-form video.
• Hands-on native experience: Proven capability building and optimizing campaigns on Taboola, Outbrain, or similar native platforms.
• Funnel mastery: Strong working knowledge of advertorials, long-form landing pages, and direct-to-checkout flows.
• Google Ads & GMC proficiency: Solid expertise with Performance Max, Google Shopping, keywords, and Merchant Center feed management.
• Time zone overlap: Minimum 6-hour daily overlap with US Eastern Time (10:00 AM–4:00 PM ET).
• Language skills: Proficient in English (written and verbal) for clear team collaboration.
• AI & data fluency: Daily use of AI tools for research, ideation, and rapid workflow execution, combined with strong data analysis capabilities.
   

BONUS POINTS
 

• Background running Meta alongside Google/YouTube/Native campaigns.
• Experience navigating policy restrictions in the supplement, health, or beauty niches.
• Hands-on experience with attribution platforms (Triple Whale, Northbeam, etc.).
• Proven experience scaling DTC brands from six to seven figures per month.

Backend Developer (Node.js / TypeScript): Android Infrastructure, Reverse Engineering, High-Load

We are looking for a strong Backend Developer for a high-load project connected with Android infrastructure, reverse engineering, network traffic analysis, and processing large amounts of data.

The main backend is built on Node.js, so strong knowledge of JavaScript and TypeScript is required.

Please note: this is not a web development position. You will work with software — native Android applications, their internals, and their network communication — not with websites or browser-based web applications. Candidates without hands-on experience working with software at this level will not be considered.

Responsibilities

• Develop and maintain backend services using Node.js / TypeScript.
• Work with high-load and distributed systems.
• Design systems for storing and processing large amounts of data.
• Work with PostgreSQL, ClickHouse, and Redis.
• Optimize database queries, indexes, and data structure.
• Work with replication, sharding, partitioning, distributed data, high availability, and fault tolerance.
• Work with Kubernetes infrastructure.
• Find and fix performance problems in backend, databases, and infrastructure.
• Analyze network traffic and the communication of native Android applications.
• Work with traffic sniffing and proxy tools.
• Understand how mobile applications communicate with backend services and APIs.
• Analyze requests, responses, headers, payloads, tokens, and sessions.
• Work with existing code and systems with limited documentation.
• Find technical problems and propose solutions independently.
• Work with distributed workers, services, and nodes.

Required Skills

Software / Reverse Engineering / Network Analysis (mandatory)

• Hands-on experience with Android reverse engineering (not just theoretical understanding).
• Practical experience intercepting and analyzing traffic of native applications (mitmproxy, Burp Suite, Charles, Frida, or similar).
• Understanding of Android architecture.
• Good understanding of HTTP / HTTPS.
• Understanding of TLS, including certificate pinning and how it affects traffic analysis.
• Experience with proxy-based traffic analysis.
• Understanding of authentication, sessions, cookies, and tokens at the application level.

Backend

• Strong experience with Node.js.
• Strong knowledge of JavaScript and TypeScript.
• Good understanding of async programming.
• Understanding of the Node.js event loop.
• Experience with REST API and WebSocket.
• Experience with high-load backend systems.

Databases

• Strong experience with PostgreSQL.
• Strong experience with ClickHouse.
• Strong experience with Redis.
• Good understanding of indexes, query optimization, query plans, replication, sharding, partitioning, distributed databases, data consistency, and high availability.

Experience with large databases and high traffic is very important.

Infrastructure

• Kubernetes.
• Docker.
• Linux.
• Experience with cluster systems.
• Understanding of networking, load balancing, and horizontal scaling.
• Ability to find CPU, RAM, disk, and network bottlenecks.
• Experience with logs and monitoring.

Important: read before applying

This role is about software, not web applications.

Our backend does not serve a website or a typical web product. It supports infrastructure built around native Android applications: we analyze how the apps work, how they communicate over the network, and we process the data at scale.

This is a strict requirement:

• You must have real, practical experience working with software (native/mobile applications): analyzing app behavior, intercepting and inspecting traffic, understanding protocols, sessions, and tokens at the application level.
• Experience limited to web development (websites, admin panels, CRUD APIs for web frontends, e-commerce, CMS) is not sufficient, regardless of seniority.
• Applications without this experience are not reviewed.

The candidate should understand the full system:

application → network → backend → databases → infrastructure

The developer should be able to work independently, research technical problems, understand existing systems, and find solutions even when documentation is limited.

Level

Strong Middle / Senior Backend Developer

Will be a plus

• Large-scale data processing.
• Complex or undocumented APIs.
• Systems with many workers and nodes.
• Experience with Frida, native libraries (JNI / .so), or protocol analysis beyond HTTP (protobuf, gRPC, custom binary protocols).

Your responsibilities
Development

• Own the electronics architecture of the device: processor platform, power supply, sensing, actuation, display, connectivity.
• Circuit design and PCB layout, from concept through to release
• Analogue measurement chains for pressure, temperature and flow sensing — low noise, low drift, calibratable.
• Drive electronics for pumps, valves, heating and cooling elements, including the power stages.
• Build, bring-up and characterisation of prototypes.
• Safety and evidence.
• Electrical safety concept under IEC 60601-1: insulation coordination, creepage and clearance distances, protective earth, single-fault safety.
• EMC-compliant design under IEC 60601-1-2, pre-compliance measurements and support through certification testing.
• Design of an independent hardware protection layer: watchdog, interlocks, pressure and temperature limiting.
• Contribute to risk management under ISO 14971; derive and verify hardware risk control measures.

• Design verification: test planning, execution and documentation as part of the technical file

   

Production readiness

• Design for reprocessing: connectors, sealing concepts and resistance to cleaning and disinfecting agents across the specified service life.
• Design for manufacturing and test: test strategy, production programming, test fixtures.
• Component qualification, second sources, long-term availability and obsolescence management.
• Work with EMS providers, prototype builds and production ramp-up
   

Collaboration

• Work closely with embedded software: platform decisions are made together, not one after the other.
• Interface with mechanical engineering, systems engineering, regulatory affairs and manufacturin.

Required

• Several years in electronics development for complex embedded devices, from schematic to finished layout (7+ as a guide).
• IEC 60601-1 or an equivalent product safety standard (e.g. IEC 61010) — insulation concepts, creepage and clearance, single fault analysis are routine for you, not new ground.
• Solid practice in analogue measurement: sensor front-ends, ADC interfacing, noise, offset and drift, calibration concepts.
• EMC-compliant design in practice — including the experience of analysing and fixing a failed EMC test.
• Confident with a professional EDA tool (Altium, KiCad, Cadence or comparable).
• Lab measurement skills: oscilloscope, spectrum analyser, network analyser, thermography
• Fluent German and English
   

Nice to have

• Medical devices and the associated documentation (design history file, design verification).
• Further parts of the 60601 series, in particular -1-2 (EMC), -1-6 (usability) and -1-8 (alarm systems)
• Mains-side power electronics, switch-mode supplies, isolation barriers, motor drive.
• Signal and power integrity on fast interfaces (DDR, LVDS, Ethernet).
• Modern 32-bit microcontroller platforms and the circuitry around them.
• Thermal design and simulation.
• Experience setting technical direction across distributed or partner teams.

What we explicitly do not require

• Prior experience in our application field. We will teach you the domain.
• Every line of the list above. If three quarters fit and you want to learn the rest, apply.

Hello — I'm Artem, co-founder of Halo Lab, a design-led product development company trusted by over 500 startups and established brands like Nokia, Zoom, and Opera.

I'm looking for a Business Development Manager to help us grow Halo Lab's presence across the Middle East, with a primary focus on the Fintech vertical. Your focus will be on relationship-driven, high-touch business development — not volume-based outbound. This is a market where trust, presence, and local understanding move deals forward far more than cold emails do.

You'll identify and engage with strategic Fintech companies across KSA, UAE, and the broader Middle East, build relationships with founders and decision-makers, attend regional events and conferences in person, and work closely with me to move targeted opportunities forward.

This is not a role for mass outreach or quick wins. It's for someone who genuinely knows how to network in the region, isn't afraid to get on a plane for the right meeting, and understands that in Middle East fintech, relationships are the pipeline.

! If you have strong experience in Fintech or the region but lack a few of the requirements below, I still encourage you to apply.

Key Responsibilities

• Research and prioritize high-fit Fintech companies and decision-makers across KSA, UAE, and the wider Middle East.
• Build and execute a relationship-first business development strategy — in-person meetings, industry events, and warm networking over cold outbound.
• Travel regularly to the region for client meetings, conferences, and industry events to build face-to-face trust.
• Initiate and nurture relationships with Fintech founders, product leaders, and investors across the ecosystem.
• Represent Halo Lab as a premium design and software development partner in high-stakes enterprise conversations.
• Collaborate with the internal team on proposal prep, intro decks, and tailored case study materials.
• Own lead tracking and handoffs, ensuring clarity and coordination with colleagues.
• Contribute insight on regional market trends, buyer behavior, and ecosystem movements specific to Middle East fintech.

Requirements

• Based in Turkey (strong priority, given travel distances) or Europe.
• Proven experience in business development or sales within the Fintech niche.
• Track record selling design, software, or digital services (agency or consultancy background a plus).
• Willing and able to travel regularly for in-person meetings across the region.
• Strong conversational English, sharp networking instincts, and confident outbound skills.
• Highly organized, proactive, and able to move from research to action without needing hand-holding.

Bonus Points For

• Experience working with KSA, UAE, or broader Middle East markets and a real understanding of local business culture.
• Existing relationships within the Middle East fintech network — founders, investors, or ecosystem players.
• Familiarity with the design/dev agency model (especially web, mobile, UX, and branding work).
• Additional languages relevant to the region.

What You'll Get

• A front-row seat to Halo Lab's growth in one of the most dynamic fintech markets in the world.
• Direct, hands-on collaboration with the founding team.
• Flexible, remote-first culture with travel built into the role.
• Competitive base salary depending on experience + performance-based bonus (this is a strategic role, not a commission-driven one).

How to Apply
If this role excites you, please check the following links before applying:

Then send your CV and a short note on how you see yourself aligned with this role. We're not in a hurry with this hire — the key thing is finding someone aligned with us on vision and approach.

We are looking for a Simulation Engineer to build and run the simulation tooling behind
slot game mathematics within an iGaming product. You turn mathematical specifications
into fast, reproducible, config-driven simulations, validate the results, prepare math
validation reports, and support developers and QA during integration and testing. The
mathematical model itself is owned by a Game Mathematician you will work with closely.
Prior iGaming experience is welcome but not required.

Responsibilities
- Build and maintain a config-driven simulation framework for slot games: reels /
  weights, paytables and feature parameters defined in configuration rather than in code.
- Make the tooling usable directly by the Game Mathematician, so balancing iterations
  can be run without engineering involvement.
- Run and analyze Monte Carlo simulations to validate RTP, payout distribution,
  volatility, hit rate and max win frequency, including convergence and confidence
  intervals.
- Prepare math validation reports generated from simulation runs, with reproducible
  results (seeded runs, versioned configurations) and result export.
- Generate the tables, configuration files and exports that accompany the mathematical
  documentation.
- Cross-check simulation results against analytical calculations and simplified
  known-answer configurations.
- Write and maintain tests for payout calculation logic, and regression checks on RTP
  across configuration changes.
- Support developers and QA during integration and testing phases: reconcile differences
  between the reference simulation and game engine test runs.

Optional / Additional Responsibilities
- Build visualization and reporting tools for payout distributions.
- Set up CI for simulation runs and automated regression on configuration changes.
- Participate in the full game lifecycle (from concept to release).

Requirements
- Strong Python at an engineering level: numpy, vectorization, profiling, working with
  large data volumes.
- Experience building config-driven, reproducible tools rather than one-off scripts,
  including seeded runs and versioned configurations.
- Applied statistics: confidence intervals, convergence, variance, and working with rare
  events and distribution tails.
- Ability to work precisely from a written technical specification, raising ambiguities
  rather than resolving them independently.
- Testing discipline: unit tests on calculation logic, and validation of simulated
  results against analytical values.
- Strong analytical thinking, attention to detail, and ownership of results.

Nice to Have
- Experience in iGaming or with casino game mathematics.
- Background in a domain involving applied probability: quantitative finance, actuarial
  work, sports betting, computational physics, or operations research.
- Performance optimization experience (Numba, Cython, C++ or Rust).
- Experience with CI pipelines for computational workloads.
- Understanding of compliance and regulatory requirements in iGaming.
