Who we are:

Adaptiq is a technology hub specializing in building, scaling, and supporting R&D teams for high-end, fast-growing product companies in a wide range of industries.

About the Product:

We support a data-intensive web platform that integrates creative assets and performance metrics across multiple advertising networks. The system ingests videos and images from various sources, applies automated tagging to extract rich feature metadata, and consolidates campaign data for analysis. On top of this analytics core, the platform delivers AI-driven insights and recommendations - highlighting best-performing elements, alerting on underperforming creatives, and enabling users to generate new assets based on historical performance data. The application handles large volumes of time-series and relational data, complex KPI calculations, and delivers near-real-time dashboards and alerts. Delivering reliable, performant queries at scale and extending the system with new end-to-end features are critical challenges that demand strong engineering expertise.

About the Role:

As a Full Stack Engineer, you will take ownership of key features across the entire technology stack-from data modeling and API design to user interface implementation and production monitoring. You will influence architectural decisions, contribute to building a maintainable and scalable codebase, and work in close partnership with product managers, data engineers, and AI specialists. This role requires balancing new feature development with system preservation, diagnosing and resolving complex issues in a data-heavy environment, and upholding high standards for code quality, testing, and documentation. Your contributions will directly shape the product roadmap and the experience of enterprise-level customers.

Key Responsibilities:

• Design, implement, and own full-stack features from planning through deployment and monitoring.
• Participate in architectural discussions to ensure systems are scalable, reliable, and maintainable.
• Write clean, testable, and well-documented code, following established best practices.
• Develop and maintain SQL queries and data models for complex, high-volume datasets.
• Diagnose and resolve performance issues and system outages, driving improvements in platform reliability.
• Collaborate with Product, Data, and AI teams to translate requirements into technical solutions.
• Conduct code reviews and share knowledge to improve development workflows and team capabilities.
• Implement automated testing (unit, integration, end-to-end) and monitoring for critical services.
• Stay current with modern technologies and propose tools or processes to enhance developer experience.

Required Competence and Skills:

• 5 years of experience building, running, testing, and monitoring web applications.
• Proficiency in Node.js, JavaScript, React, TypeScript, and SQL.
• Hands-on experience with cloud platforms ( GCP or AWS) and deployment pipelines.
• Deep understanding of relational database design, indexing, and query optimization.
• Strong testing methodology and experience with documentation and monitoring frameworks.
• Ability to identify, diagnose, and fix complex issues while improving code readability and system reliability.
• Excellent communication skills, self-starter mindset, and proactive organization.

Nice to Have:

• Experience with Kubernetes, Docker, Flux, or similar container orchestration tools.
• Familiarity with DevOps and infrastructure-as-code practices.
• Appreciation for clean code principles and continuous learning.
• Previous work experience in early-stage startups or rapidly evolving environments.

Why Us:

- We provide 20 days of vacation leave per calendar year (plus official national holidays of a country you are based in).

- We provide full accounting and legal support in all countries we operate.

- We utilize a fully remote work model with a powerful workstation and co-working space in case you need it.

- We offer a highly competitive package with yearly performance and compensation reviews.

About the Role

We are looking for a Senior Application Security Engineer (Cryptography) to join a Client’s team building a Zero-Knowledge, privacy-first product.

This role is for an internal adversary and cryptography architect — someone who validates that our Zero-Knowledge and security claims are mathematically sound, not just marketing statements.

Your mission is to actively attack our own system, identify cryptographic flaws, detect metadata leaks, and prevent key compromise before real attackers do.

Location: Remote
Cooperation Type: Full-time, long-term
Experience Level: Senior
Start: ASAP

Responsibilities

• Audit and validate cryptographic protocols (Signal Protocol, MLS, Zero-Knowledge Proofs / ZK-SNARKs)
• Review and assess security-critical implementations in mobile and backend systems
• Conduct threat modeling for Zero Trust and Zero-Knowledge architectures
• Identify vulnerabilities in mobile applications and cryptographic flows
• Perform security code reviews in Swift, Kotlin, and Java
• Execute penetration testing and security assessments using Burp Suite, Frida, Wireshark, Ghidra
• Perform mobile application security analysis (SAST / DAST)
• Design and review Private Set Intersection (PSI) schemes for secure contact discovery
• Audit secure local storage and offline-first encryption strategies (SQLCipher, Encrypted SQLite)
• Validate hardware-backed security usage (Secure Enclave / Android Keystore)
• Detect and mitigate metadata leaks, privacy risks, and key compromise threats
• Work closely with engineering teams to fix vulnerabilities and improve system security
• Document findings, security recommendations, and cryptographic risks

Requirements

• 6+ years of experience in application security, cryptography, or security engineering
• Deep understanding of cryptographic protocols (Signal Protocol, MLS, Zero-Knowledge Proofs / ZK-SNARKs)
• Strong knowledge of applied cryptography and encryption principles
• Experience reviewing and auditing security-critical code in Swift, Kotlin, or Java
• Experience with mobile application security and client-side threat models
• Hands-on experience with penetration testing tools (Burp Suite, Frida, Wireshark, Ghidra)
• Experience conducting SAST / DAST and mobile security assessments
• Experience designing or reviewing Private Set Intersection (PSI) solutions
• Experience with threat modeling for Zero Trust architectures
• Strong understanding of secure local storage and offline-first encryption (SQLCipher, encrypted SQLite)
• Familiarity with hardware-backed security (Secure Enclave, Android Keystore)
• Ability to think like an attacker and proactively break systems before others do
• English: Upper-Intermediate or higher

Nice to Have

• Experience working on Zero-Knowledge systems in production
• Experience with formal cryptographic verification or research
• Experience with reverse engineering mobile applications
• Background in security research, bug bounty, or CTFs
• Experience with privacy-preserving systems or anonymous networks
• Contributions to open-source security or cryptography projects

What We Offer

• Competitive compensation according to your experience (gross system)
• Fully remote work and long-term cooperation
• Opportunity to work on a deeply technical, cryptography-heavy security role
• Direct impact on core Zero-Knowledge and privacy architecture
• Fast hiring process and quick decision
• Supportive engineering culture focused on security, correctness, and ownership

What happens after you apply

• Quick CV review
• Short recruiter call
• Technical interview with LITSLINK team
• Technical deep-dive with the Client
• Fast decision & offer
