#вакансия #fulltime #remote #python #vue

Vacancy: Middle AI Engineer (Fullstack)
Company: Mad Devs
Salary: 2000 - 3000$ gross
Work format: Full-time

We are looking for an engineer who can work effectively in a complex environment: understand existing systems, improve them carefully, deliver new features, and reduce technical debt without breaking production.

What will need to do:
• Delivering product features end-to-end
• Working with existing Enji services: understanding, extending, and refactoring them
• Participating in design sessions with PMs, BAs, and designers: challenging assumptions, proposing alternatives, and estimating implementation complexity
• Prototyping complex flows in Cursor / v0 before they become formal specifications
• Addressing technical debt thoughtfully and with clear reasoning
• Reviewing pull requests from other developers, including juniors and mid-level engineers

Requirements:
• 3+ years of commercial software development experience; 1+ year in AI engineering
• Production experience with Python (FastAPI or Flask — what matters is real-world usage with migrations, testing, and production deployments)
• Production experience with Vue 3 (Composition API, TypeScript, reactivity, component architecture). React experience alone does not satisfy this requirement — Vue is the primary frontend framework at Enji, and onboarding speed matters
• PostgreSQL: migrations, indexing, and basic understanding of query plans
• Docker / docker-compose — ability to build and run a local stack independently
• Git proficiency: rebase workflow, atomic commits, meaningful commit messages
• Hands-on experience using AI tools in day-to-day development (Cursor / Claude Code / Copilot / Codex / others)
• Language Proficiency: English at B2-C1 level, Russian at C2 level

Will be a plus:
• Quasar — the entire frontend stack is built on it
• Experience with message buses (NATS / Kafka / RabbitMQ / Redis Streams) — inter-service communication is based on NATS
• Experience with Clean Architecture or similar patterns (DDD, Hexagonal Architecture)
• Experience with CASL or other authorization systems
• Experience with background job processing (Celery, APScheduler, RQ, or any scheduler)

Vacancy: Junior DevOps/Systems Engineer
Company: Mad Devs
Salary: 1500-2000$ gross
Work format: remote/full-time
About Us: Mad Devs is a full-stack team specializing in developing and administering large-scale IT products across diverse industries. Many of our products operate in Europe, the USA, and countries across Southeast Asia. We are passionate about tackling complex challenges and delivering innovative solutions that make a meaningful impact globally.
**What will need to do:
**Identity, SSO & Access Management
• SSO & IdP — configure and maintain SSO integrations (SAML, OIDC, SCIM) across our SaaS stack, and keep our identity provider clean and well-governed.
• Account management — provision, modify, and deprovision accounts across productivity and engineering tools; manage groups, roles, and permission boundaries.
• Access requests — triage and fulfill access requests with appropriate approvals; document why access was granted and review it on a regular cadence.
Onboarding & Offboarding
• Onboarding — equip new hires with the accounts, tools, hardware, and access they need before day one, and walk them through it.
• Offboarding — execute clean, auditable offboarding: revoke access, recover assets, preserve data per policy, and close the loop with people ops.
IT Administration & Productivity Systems
• Day-to-day admin — administer Google Workspace, Slack, identity providers, MDM, password managers, and the rest of our SaaS productivity stack.
• Internal support — be the first line of help for employees with IT issues; resolve, escalate, and document.
Security Controls & Monitoring
• Controls — enforce baseline security configurations across SaaS apps, endpoints, and identity (MFA, conditional access, least privilege).
• Monitoring — watch our security tooling for anomalies and alerts; investigate, triage, and escalate as needed.
• Compliance support — help keep us audit-ready by maintaining clean records of access, changes, and reviews.
Automation & Scripting
• Light coding — automate the parts of the job that should be automated. Expect to write Python, Bash, or TypeScript glue code, hit SaaS APIs, and build small internal tools.
• Continuous improvement — improve the systems and runbooks you inherit; if a process is painful or manual, fix it.
Requirements:
• 0–3 years in IT engineering, IT operations, systems administration, or a similar role (internships and substantial side projects count)
• Working knowledge of SSO and identity concepts: SAML, OIDC, SCIM, MFA, and the difference between authentication and authorization
• Comfort in a terminal and with at least one scripting language (Python, Bash, or similar). You should be comfortable writing code, testing it, and committing it using git
• A security-first mindset: you understand least privilege, you don't share credentials, and you take audit trails seriously
• Strong written communication. You can explain a fix to a non-technical teammate and document a process so the next person doesn't have to ask
• A bias toward ownership. When something breaks, you don't wait to be told; you investigate and follow through
• Availability to work hours that overlap with the US Central Time (CST) zone (at least 4–5 hours of daily overlap with the team)
• English and Russian at B2 level, for communication with stakeholders and team
• Location: any, except Russia and Belarus
