Location: Poland; United Arab Emirates; Brazil; Argentina; Spain; Serbia Imunify360 is a leading developer of Linux infrastructure and security solutions. Our flagship product, Imunify360, is a comprehensive security suite that protects thousands of shared hosting environments, VPS, and dedicated servers worldwide. Our clients include industry giants such as Dell, GoDaddy, IBM, and Zoom, with over 4,500 customers globally. The company has more than 250 employees. We are looking for an engineer-architect to build a new product from scratch . This is not a position within an existing team—you will single-handedly create a runtime protection layer for Node.js applications. The hosting market is rapidly adopting Node.js, and modern applications are increasingly generated by users with AI tools and little technical security expertise. Your mission is to make protection automatic, transparent to client code, and effective in real time. This is a role with the highest level of ownership (Senior / Staff / Architect level), where you will make key architectural decisions and take full responsibility for the outcome. Responsibilities Define the technical approach for building runtime protection inside the Node.js process. Design the detection logic to identify and block attacks during application execution. Build and launch the first version of the product in real production environments. Ensure the protection works without requiring changes to client code and without breaking legitimate applications. Continuously improve the product based on telemetry, production feedback, and real-world incidents. Achieve target values across four key metrics: Runtime overhead False positives False negatives Customer escalation volume Requirements The top priority is Security, not just Node.js. Security experience outweighs general backend tenure. Must-have: Experience in Security Engineering or Security Research (deep understanding of attack vectors and defense methods). Have independently built and shipped a product/solution from scratch (end-to-end ownership: from idea to production). Ability to take an ambiguous problem, define a solution, and deliver a working result without constant supervision. Experience designing architecture and making key technical decisions (Staff/Architect level is a strong plus). English language: Intermediate or higher (written and spoken — all interviews are conducted in English). Nice-to-have: Security experience specifically in the context of Node.js (vulnerability analysis, securing, researching Node.js applications). Experience with Linux in production and development environments. Knowledge of Runtime Protection, WAF, instrumentation, malware analysis, and Incident Response. Experience in managed hosting / VPS domains. Experience with AI coding agents (Copilot, Cursor, etc.). Important: If you are a Security Engineer / Researcher who doesn't code on a daily basis, you must be comfortable using AI-assisted development tools and be capable of building an MVP with their help. Who you are (mindset): Builder: You genuinely enjoy creating something new and seeing it run in production. High ownership: You don't wait for tasks to be assigned — you define the approach and own the results. Practioner: You write code (yourself or with AI), not just review and coordinate. You understand Detection Engineering — how detection rules behave at scale across thousands of servers and the true cost of false positives. We do NOT consider candidates who: Have only theoretical or research experience without shipping real products. Have general Node.js development experience but lack a security component. Reside in countries with complex B2B tax reporting requirements (USA, UK, Canada, Germany, France, and others — to be clarified during screening). Have frequent job changes (every 1–2 years) without valid reasons. Benefits Format: 100% remote work anywhere in the world. Legal setup: B2B only (contract with your sole proprietorship or company). Budget: Up to $12,000 gross/month (before taxes, under a B2B agreement). Company: A stable, established international product company with 15+ years in the market. Role: A key position in building a new product line from the ground up.

Location: Poland; Georgia; Armenia; Spain; Greece; Serbia We are hiring a Senior Database Reliability Engineer to join the Infrastructure DBA cell. This is a hands-on production ownership role, not a narrow ticket-processing DBA position. You will keep critical database services reliable, automate repeated work, support engineering teams, and reduce single-person dependency in our PostgreSQL, ClickHouse, MongoDB, and Redis operations. PostgreSQL is the main requirement. ClickHouse experience is a strong plus, but it is not a day-one blocker. We need a senior engineer with enough database, Linux, automation, and incident-response depth to learn our ClickHouse environment quickly and operate it safely. Your Responsibilities: Own production PostgreSQL reliability: HA design, Patroni, PgBouncer, replication, failover, upgrades, vacuum/bloat control, query tuning, locks, indexes, capacity, backups, PITR, and restore validation. Improve disaster recovery and operational evidence: tested restores, documented recovery paths, measurable RTO/RPO targets, runbooks, and safe maintenance plans. Support the wider database estate: ClickHouse, MongoDB, and Redis. You will troubleshoot incidents, review access and data-safety changes, improve monitoring, and learn the production ClickHouse patterns already in use. Automate DBA workflows with Ansible, Terraform/OpenTofu, GitLab CI/CD, scripts, and reproducible runbooks for provisioning, grants, backups, restores, health checks, and ownership metadata. Help build DBaaS-style self-service capabilities so engineering teams can request databases, access, credentials, and operational checks with less manual DBA intervention. Improve observability and incident response through Grafana, metrics, logs, SLOs, alert rules, Opsgenie routing, and clear communication during production issues. What Success Looks Like: PostgreSQL clusters have tested backup and restore paths, useful dashboards, clear ownership, and documented failover procedures. Repeated DBA tickets become automation or self-service workflows. ClickHouse operational knowledge is no longer a single-person dependency. Database incidents have owners, runbooks, evidence, and measurable recovery paths. Product and engineering teams get database help faster without sacrificing safety, auditability, or reliability. Why Us? You will work on real production infrastructure used across products. You will have a direct impact on reliability, incident response, developer experience, and operational resilience. You will also work in an AI-assisted engineering culture where automation, documentation, Claude, Codex, and careful human verification are part of the daily operating model. Requirements What We Expect From You: Deep hands-on PostgreSQL experience in business-critical production environments, typically 5+ years or equivalent depth. Strong understanding of PostgreSQL internals and operations: MVCC, WAL, transactions, locks, indexes, query planning, replication, autovacuum, bloat, major upgrades, backups, PITR, and restore testing. Proven experience with highly available databases and the ability to reason about quorum, split-brain risk, failover, rollback, and recovery. Strong Linux and infrastructure fundamentals: systemd, networking, storage, filesystems, CPU/memory/disk bottlenecks, TLS, DNS, firewalls, and root-cause troubleshooting. Automation skills with Ansible and scripting. Terraform/OpenTofu, GitLab CI/CD, and merge-request based delivery are strong advantages. Ability to support more than one database engine. You do not need to be a ClickHouse expert on day one, but you must be ready to learn it quickly and take responsibility for it. Practical use of AI engineering assistants such as Claude and Codex. We expect you to use them to improve speed and quality, while personally verifying generated SQL, commands, scripts, and operational conclusions. English - upper-intermediate or higher - to ensure clear communication of progress within the teams. Nice to Have: ClickHouse operations: replication, Keeper/ZooKeeper, MergeTree engines, distributed DDL, grants, row policies, backups, query troubleshooting, and cluster recovery. MongoDB replica sets and Percona Backup for MongoDB. Redis/Sentinel and broker/cache failure modes. Database observability, SLOs, golden signals, alert tuning, and executable incident runbooks. Building internal platforms, self-service portals, or DBaaS workflows for engineering teams. Benefits A focus on professional development. Interesting and challenging projects. Fully remote work with flexible working hours, which allows you to schedule your day and work from any location worldwide. Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leaves. Compensation for private medical insurance. Co-working and gym/sports reimbursement. Budget for education. The opportunity to receive a reward for the most innovative idea that the company can patent.

Location: United Kingdom; Moldova We need someone who understands data deeply and uses Python to wrangle it — not a platform engineer, not a pure pipeline builder, but a data specialist who's comfortable with research, investigation, and the unglamorous work of making messy energy market data actually usable. You'll spend significant time on tasks like: mapping BM units to power plants and fuel types, reconciling legacy data formats with current ones, ensuring consistency between different Elexon message types, and cleaning time-series data (outliers, gaps, overlaps). Some of this requires genuine investigation — cross-referencing sources, making judgment calls, documenting edge cases. There's no API that solves these problems for you. Python is your primary tool (Pandas, Numpy, standard libraries) to minimise manual effort, but you should be comfortable that some detective work is unavoidable. If you find satisfaction in truly understanding a dataset's structure and quirks — rather than just piping data through and hoping for the best — this role is for you. Data Mapping and Research • Map BM units from Elexon to their corresponding power plants, substations, and fuel types — combining API data, public registers, and manual research • Map substations to ETYS zones and grid supply points • Build and maintain reference/master datasets that link identifiers across disparate sources (Elexon, National Grid ESO, TEC register, etc.) • Document mappings, assumptions, and known limitations clearly for downstream users Data Reconciliation and Consistency • Reconcile legacy data formats with current formats (e.g., historical operational data stored in different schemas or granularities) • Ensure consistency between different Elexon message types — understand the market data structure well enough to know why BOALF, BOD, and DISBSAD might not perfectly align and how to handle it • Investigate discrepancies between data sources and determine authoritative values Data Cleaning and Quality • Clean time-series data: detect outliers (price spikes, meter errors), fill gaps appropriately, resolve overlapping or duplicate timestamps • Develop reusable Python-based cleaning routines that can be applied across datasets • Understand why data quality issues occur (settlement reruns, late submissions, format changes) not just patch them Pipeline Development (Supporting the Above) • Write and maintain Python data grabbers for energy market APIs • Build dbt models to transform raw data into clean, analysis-ready datasets • Orchestrate workflows via GitHub Actions • Design PostgreSQL schemas that reflect your understanding of the domain Requirements • Strong Python skills for data work — you're fluent with pandas, comfortable writing clean, testable code, and can build reusable data processing logic. This is not an Excel role. • Solid SQL skills — complex queries, window functions, CTEs in PostgreSQL • Experience with messy, real-world data — you've done reconciliation, cleaning, or mapping work before and understand it's not always automatable • Methodical and detail-oriented — you notice inconsistencies and want to understand root causes • Good documentation habits — you know that undocumented mappings and assumptions are technical debt • Self-directed — you can own ambiguous problems, do your own research, and communicate findings clearly Nice to Have • Experience with energy, utilities, or market data (any geography) • Familiarity with UK energy markets, Elexon data, or grid operations • dbt experience for transformation pipelines • Exposure to time-series data challenges (irregular timestamps, gaps, restatements) Highly Desirable — Agentic AI Coding Experience We value candidates who can build software using agentic AI coding systems. This is fundamentally different from using code completion tools or chat-based assistants. Not What We're Looking For • Platform/infrastructure engineers who prefer to stay above the data layer • People who expect clean, well-documented data as input • Those uncomfortable with research, ambiguity, or "manual" investigation work Practicalities • Remote-first with async collaboration (Slack, GitHub, documented decisions) • Core overlap with UK business hours expected (at least 4 hours daily) • Competitive compensation based on location and experience Benefits Plenty of opportunities for learning and professional growth B2b contract with a paid vacation
