Старший fullstack-разработчик

Location: Baku, Azerbaijan
Type: Full-time
Company: DRL LLC
About EiGroup
At eiGroup, we believe ideas can change industries - but only if they are nurtured with structure, science, and courage.
We’re an R&D and Innovation Venture Studio that transforms human ingenuity into technological value that scales.
Our ecosystem brings together researchers, engineers, and creators who turn complex challenges into scalable products - from subsurface imaging to AI-driven analytics, from remote sensing to digital transformation.
Our ventures are built in-house, born from research, and grown into independent companies.
Together, we’re shaping how innovation takes root in this region - and how it reaches the world.
What You'll Do

• Own the backend: design, build and maintain scalable services and RESTful APIs in C# and ASP.NET Core
• Build and maintain features in a modern React + TypeScript application: complex editable data grids, charts, and document-style editors
• Integrate with, and participate in developing, Python-based AI services
• Own application-level architecture — API contracts, module boundaries, data model — participate in solution-level design, and recording the decisions behind it as ADRs
• Design the data model and build against a relational database — schema design, ORM, migrations, query optimization and performance tuning
• Implement authentication, authorization and role-based access control using Microsoft Entra ID, JWT and OAuth2, including row-level data restrictions
• Build real-time and collaborative features using SignalR hubs
• Participate in CI/CD, containerization and deployment together with DevOps
• Break complex work into deliverable increments, estimate it credibly, and flag risk early
• Partner with the Project Manager and domain experts to shape and clarify requirements: surface the edge cases, challenge scope, and propose the cheaper version when there is one
• Write unit and integration tests, raise line and branch coverage on the code you own, and keep the CI quality gates — static analysis, linting, type checks — green
• Mentor engineers as the team grows — thorough code review, pairing, and setting the standards the codebase is held to
  

What You Bring

• 5+ years of professional full-stack experience with a strong backend focus
• Strong professional experience with C# and ASP.NET Core
• Deep understanding of backend architecture — dependency injection, middleware, asynchronous programming, and the trade-offs between them
• Proven experience designing and implementing RESTful APIs that other teams consume
• Strong experience with relational databases: database design, ORM (e.g. EF Core), query optimisation and performance tuning
• Experience with Microsoft Azure — compute, messaging, secrets management and managed identities
• Experience with SignalR, message brokers, or comparable messaging and real-time technologies
• Experience implementing authentication and authorization with JWT, OAuth2 and Microsoft Entra ID
• Solid working knowledge of React and TypeScript, and experience integrating frontends with backend APIs
• Experience with Git, CI/CD workflows, and shipping to production regularly
• Track record of owning a system end to end — design, build, deploy, operate — not only delivering assigned tickets
• Ability to make and defend architectural decisions with incomplete information, and to write them down
• Comfortable working in an existing codebase — reading unfamiliar code, deciding what to keep, and refactoring the rest safely
• Sound instincts on application security — you recognise an authorization gap or an unsafe default in review
• Good written and verbal communication in English, including with non-technical domain experts
• Ability to work independently in a fast-paced environment — break down and estimate complex work, prioritise effectively, and raise risks early
  

Nice to Have

• Python and FastAPI
• Experience integrating LLM or RAG services into production applications
• Experience building analytical, reporting, or business intelligence applications
• Experience with offline-first or occasionally-connected applications, and conflict resolution
• Experience working with large datasets, data visualisation, or time-series data
• Experience with distributed systems and event-driven architecture
• Experience with Docker and Kubernetes
• Experience mentoring engineers or leading a small team
• Domain exposure to energy, oil & gas, or industrial/engineering software
  

Our Benefits Include

• Medical insurance (family coverage)
• Flexible working hours
• Wellness program
• Childcare support
• Company-provided lunch
