We are looking for a Full-Stack Developer who will own the end-to-end technical implementation of marketing landing pages and lead flows.

The role is execution-critical: converting AI-generated or Next.js-based pages into pure HTML / CSS / JavaScript landing pages, integrating them with Keitaro, configuring GTM and analytics, ensuring accurate CRM data delivery, and controlling conversion logic and lead qualification flows.

This position sits at the intersection of marketing, tracking, and backend integrations. The goal is not “development for beauty,” but development for control, accuracy, and scale.

Core Responsibilities

Landing Pages & Front-End Execution

  • Strict adherence to required data structures
• Debug and monitor lead delivery to prevent:
  • Field corruption
  • Missing parameters
  • Broken flows
     

System Ownership

• Be responsible for the entire lead flow lifecycle:
  • Page → Tracker → CRM → Conversion logic
• Quickly identify and fix:
  • Broken tracking
  • Lost leads
  • Incorrect conversion firing
• Maintain clean, documented, and reproducible setups
   

Required Technical Skills

Front-End

• Strong HTML / CSS / JavaScript (whatever)
• Ability to convert design → working landing page without frameworks
• Understanding of performance optimization for marketing pages
   

Tracking & Marketing Tech

• Keitaro (mandatory)
• Google Tag Manager (GTM)
• Event-based tracking and conversion logic
• Understanding of how ad platforms consume conversion data
   

Backend / Integrations

• Working with REST APIs
• Webhooks (send / receive / validate payloads)
• CRM integrations and field mapping
• Debugging data pipelines
   

Architecture & Logic

• Conditional logic for lead qualification
• Understanding of how tracking, conversions, and CRMs interact
• Ability to think in flows, not pages
   

Nice-to-Have (Strong Advantage)

• Experience in performance marketing / arbitrage environments
• Familiarity with:
  • Meta / Google / TikTok tracking behavior
  • Conversion optimization under platform constraints
• Experience working with high-volume lead funnels
• Ability to suggest improvements in tracking or flow logic
   

Profile We’re Looking For

• Execution-driven, not theoretical
• Understands that tracking accuracy = money

Who:
We are looking for a Senior Secure Mobile Engineer with deep Flutter expertise and a strong background in applied cryptography and mobile security.

What:
You will build and secure the mobile client in a zero-knowledge architecture, where all encryption, key generation, and sensitive data handling happen entirely on the device.

When:
Immediate start.

Where:
Remote (time zone overlap preferred).

Why:
In a zero-knowledge system, the client is the gatekeeper — if the app is compromised, server security is irrelevant. This role is critical to the security, privacy, and trustworthiness of the entire platform.

Office Environment:
Small, senior-level engineering team focused on privacy, security, and high-impact architectural decisions.

Salary:
Competitive, based on experience and security expertise.

Position Overview:

This role owns the security of the mobile client. You will design and implement encryption workflows, secure storage, memory hygiene, and network protections while ensuring high performance and reliability. You’ll work on advanced cryptographic protocols, offline-first secure data handling, and privacy-preserving AI features — all running fully on device.

Core Technology Stack:

• Languages: Dart (expert), Swift / Kotlin (intermediate, for platform channels)
• Framework: Flutter (deep understanding of rendering engine, Isolates for heavy cryptographic workloads)
• State Management: Riverpod or BLoC (handling ephemeral state wiped on app close)

Key Responsibilities:

• Implement and maintain end-to-end encryption and key management on the client
• Design secure local data storage and lifecycle management
• Build Flutter platform channels for cryptographic and security-sensitive native operations
• Ensure memory hygiene by explicitly clearing sensitive data from RAM
• Implement strong network security protections against MITM and traffic analysis
• Collaborate closely with backend and security engineers on protocol correctness
• Review and harden the app against real-world mobile attack vectors

Crucial Security & Privacy Skills:

• Applied Cryptography:
  • Experience implementing Signal Protocol (Double Ratchet, X3DH) or MLS (Messaging Layer Security)
  • Deep understanding of session setup, replay attack prevention, and key lifecycle management
• Secure Storage:
  • Expert knowledge of iOS Keychain and Android Keystore
  • Experience implementing SQLCipher for fully encrypted local SQLite databases
• On-Device Search:
  • Experience building in-memory, on-device search engines without leaking data
• Memory Hygiene:
  • Writing code that actively clears keys and plaintext from memory after use
• Network Security:
  • Certificate Pinning implementation
  • Experience with Tor / Orbot or similar anonymous routing is a plus
• Local AI Integration:
  • Running on-device LLMs using TensorFlow Lite, MediaPipe, or similar
  • Ensuring AI features (summarization, translation) work offline without cloud data leakage

Ideal Candidate Profile:

• Senior-level Flutter engineer with a strong security mindset
• Comfortable owning mission-critical client security decisions
• Deep understanding of mobile OS internals and attack surfaces
• Pragmatic, detail-oriented, and uncompromising about privacy and correctness

Do you understand clients’ needs and know exactly how to offer them the solutions they really need? Is sales your passion, and do you know how to engage and attract clients?

  Collect market feedback to improve product positioning, offers, and marketing messaging.
