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:

Our client is developing a cutting-edge cybersecurity analytics platform designed to give enterprises a comprehensive understanding of their digital environments and security posture. The system continuously aggregates and correlates large-scale data from multiple sources, applies graph-based modeling and AI-driven analytics, and delivers real-time insights that help organizations prioritize and remediate high-impact risks. 

About the Role:

This is a hands-on Senior Backend Engineer role in the central platform team, focused on developing and scaling the core services behind a cybersecurity platform. The role involves designing and maintaining APIs, building reliable backend systems, and contributing to AI-driven features used in production. In collaboration with cross-functional teams, you’ll help shape system architecture, improve performance and observability, and ensure the platform remains stable and scalable. The work has a direct impact on product capabilities, integrations, and the overall user experience.

Key Responsibilities:

• Develop and maintain backend services powering the platform (primarily Python/FastAPI-based microservices)
• Design, build, and evolve APIs used across internal services and external integrations
• Ensure API reliability, scalability, and clear communication between distributed services
• Contribute to building scalable and reliable distributed systems (messaging, data flow, service communication)
• Participate in development of AI-powered features (LLM integrations, prompt-based workflows)
• Improve system quality: testing, observability, performance, and reliability
• Collaborate with other teams when working across multiple services and repositories
• Use modern development tools, including AI-assisted coding, to improve productivity and code quality
• Take ownership of tasks and proactively drive them to completion

Required Competence and Skills:

• 5+ years of backend development experience with Python
• Strong hands-on experience with FastAPI
• Solid understanding of distributed systems and microservices architecture
• Experience working with APIs (design, integration, service-to-service communication)
• Experience with async messaging systems (e.g., RabbitMQ, SQS, SNS or similar)
• Hands-on experience with AWS, including building and running cloud-based services using managed components
• Experience working with Docker / containerized environments
• Experience working with AI tools and coding agents (e.g., Claude or similar) in daily development workflows
• Strong ownership mindset and ability to work independently
• Excellent English and communication skills

Nice to Have:

• Experience building LLM-based features (Bedrock, OpenAI, Anthropic, etc.)
• Experience with Kubernetes and CI/CD pipelines
• Familiarity with data platforms (Databricks, Spark)
• Background in cybersecurity domain

About the project:

Search is changing fast. AI-generated answers are replacing ranked links, and brands that aren't visible inside those answers are simply invisible. This role exists to make sure our clients are inside those answers — not invisible to them. You'll own GEO end-to-end: auditing content for AI retrievability, building entity coverage, shaping how information is structured so language models can extract and cite it reliably. You'll also maintain solid traditional SEO foundations in parallel, because both disciplines are still in play.

A new team member will be in charge of:

• Lead GEO strategy from audit to execution — entity mapping, semantic architecture, and content structuring for AI retrievability
• Shape how content is written and organized so LLMs can extract, surface, and cite it: clear heading hierarchies, modular answer formats, entity-rich copy
• Monitor how models like ChatGPT, Perplexity, and Gemini retrieve and represent brand content — then turn findings into concrete changes
• Run traditional SEO execution in parallel: technical audits, on-page optimization, keyword strategy — keeping the foundation strong as discovery shifts

• Use AI tools (Claude, ChatGPT) actively to test prompts, validate visibility, and pressure-test content across AI search surfaces

   

Does this relate to you?

• Hands-on GEO experience (1 year active GEO practice) — you understand how LLMs source content in practice, not just in theory; prior SEO with active GEO experimentation is fully valid
• Strong SEO fundamentals (3+ years proven SEO): technical audits, on-page optimization, keyword research — you can run this independently
• You know how to structure content for machine readability: semantic hierarchy, extractable answer formats, clean entity coverage
• Solid understanding of what makes content citation-worthy inside generative systems — and what gets ignored
• Comfortable working with AI tools as part of your daily workflow, not just as an experiment

• Link building experience plus especially building off-site authority that feeds both traditional and AI-driven discovery

Your mission

Take full ownership of quality as a system, not a phase.
You will transform QA from a supporting function into a company-wide quality engineering discipline, driving process maturity, security awareness, and automation-first culture.

What you will actually do:

— Own and evolve QA strategy at the company level:
 define how quality is built, measured, and scaled across all projects

— Lead QA transformation initiatives:
 • move from manual-heavy QA to automation-first approach;
 • eliminate process chaos and introduce predictable, repeatable delivery models;
 • standardize QA practices across teamxs without killing flexibility.

— Embed security into QA processes (not as a checkbox):
 • define security testing standards;
 • integrate basic security checks into SDLC;
 • raise security awareness across engineering teams.

— Own non-functional quality:
 • performance & load testing strategy;
 • data integrity & database testing;
 • reliability for Live systems.

— Build a modern automation ecosystem:
 • define automation strategy across projects;
 • ensure frameworks are scalable, maintainable, and actually used;
 • drive high ROI automation (not “automation for the sake of automation”).

— Scale quality metrics that matter:
 • defect leakage;
 • automation efficiency;
 • team performance and delivery health.

— Build and lead a high-performance QA organization:
 • hire strong engineers, not “manual testers”;
 • grow people into T-shaped quality engineers;
 • mentor leads and shape future QA leaders.

— Partner with Engineering and DevOps to make quality a shared responsibility, not a QA bottleneck

What makes this role interesting:

— You are not “leading QA team” — you are shaping how the company builds software;
— You will work on processes that actually need fixing, not maintaining legacy bureaucracy;
— High level of ownership and decision-making power;
— Direct impact on engineering culture and delivery quality;
— Strong focus on growth and learning (courses, conferences, certifications);
 — Flexible work format (remote / office);
 — Paid vacations (23 business days) and sick leaves;
 — Full transparency on company performance.

We expect you to bring:

— Strong experience as Lead / Staff QA with real ownership of quality processes;
— Proven track record of building or transforming QA practices (not just supporting them);
— Deep expertise in:
 • test automation strategy and frameworks;
 • QA process design and scaling;
 • non-functional testing (performance, reliability, data).
— Solid understanding of security fundamentals in QA;
 (you don’t need to be a pentester, but you know where QA adds value in security)
— Experience working in multi-project / outsource environments is a big plus;
— Ability to operate on both levels:
 • strategic (define direction);
 • hands-on (get into tools, frameworks, problems when needed).
— Strong system thinking: you see QA as part of engineering ecosystem, not isolated function;
— Good technical background:
 • APIs, web, mobile;
 • logs, debugging, observability tools;
 • CI/CD understanding.
— English: Upper-Intermediate or higher.

Awesome if you have:

— Experience implementing OWASP-based practices or security testing workflows;
— Programming experience (Java / JS / Python) for building robust automation;
— Experience with quality metrics systems and data-driven decision making.
