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 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

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.

Responsibilities:

• Design and document event tracking structure, tracking plan, and naming conventions aligned to real business questions

• Participate in discovery: shape hypotheses, design experiments, identify user segments' Aha Moments
• Run end-to-end A/B testing: hypothesis, sample sizing, statistical significance, post-launch impact analysis
• Inform roadmap prioritization with data; push back when the data says otherwise
• Identify the Aha Moment for different segments: sales reps, recruiters, agencies
• North Star metric + supporting KPIs dashboard
• Funnel analytics: registration -> activation -> trial -> paid -> retention -> expansion
• User Base Overview and Account Base Overview with drill-down by status and company
• Activation flow with step-by-step drop-off and time-on-step visualization
• Cohort retention, feature adoption, MRR movement (new/expansion/churn/contraction/reactivation)
• Build dashboards across the full customer lifecycle, from acquisition and activation to retention, expansion, and churn
• Build the analytics workflow: how requests come in, how insights flow back, how they feed into roadmap
• Create and maintain a metrics dictionary, data definitions, and ownership documentation
• Drive a self-serve culture, enable PMs to pull their own data without analyst bottlenecks

Work conditions:

• 100% remote position, providing flexibility and work-life balance.

• 24 days of paid vacation per year to recharge and relax.
• 10 days of paid sick leave.
