Senior Backend Software Engineer

We are looking for a Senior Backend Engineer to join our team and contribute to the development of a customer‑facing SaaS platform focused on advanced AI‑driven workflows, orchestration, and scalability. This is primarily a backend/product engineering role where AI is leveraged as part of the system rather than being the core research focus. In this role, you will design and enhance backend services, build scalable APIs, and work on orchestration pipelines that power agent‑based AI workflows.

You will collaborate closely with experienced engineers, contribute to architectural decisions, and help deliver high‑quality solutions in a fast‑paced environment.

The project is a customer‑facing SaaS platform focused on building and scaling agentic AI workflows. The role emphasizes backend engineering and system design, with AI components integrated into the platform as part of orchestration and automation pipelines. This is not a pure AI/ML role—it’s a product/backend engineering role that integrates AI workflows.

• 5+ years of experience in backend development
• Strong proficiency in Go or Rust (one of them is highly preferred)
• Solid experience with Python (existing parts of the system are built with it)
• Proven experience building scalable backend services and APIs
• Hands‑on experience with distributed systems and service‑oriented architecture
• Strong understanding of system design, performance, and scalability principles
• Experience working with document databases and context/data storage systems
• Ability to quickly understand, modify, and extend existing codebases
• Practical experience integrating AI/LLM‑based workflows into applications (as black‑box services)
• Familiarity with agent orchestration concepts and RAG‑based pipelines
• Experience with workflow orchestration, job scheduling, or task execution systems
• Experience with cloud environments (AWS, Azure, or multi‑cloud setups)
• Strong problem‑solving skills and ability to work under tight deadlines
• Excellent communication skills and ability to collaborate in distributed teams
• Proactive mindset with a strong sense of ownership
• Flexibility in working with different technologies and tools
• Experience working in Agile/Scrum environments
• Experience using AI coding assistants (e.g., Cursor, Git Hub Copilot, or similar) in day‑to‑day development tasks

• Hands‑on experience with tools like CrewAI or similar agent orchestration frameworks
• Experience designing or working with custom RAG pipelines and context management systems
• Background in building SaaS platforms or customer‑facing products
• Experience with high‑load or real‑time systems
• Exposure to multi‑cloud infrastructure and cross‑cloud deployments
• Experience mentoring engineers or contributing to technical leadership
• Experience building AI‑powered solutions or integrating AI pipelines/APIs into software projects

• Design, develop, and maintain backend services for a scalable SaaS platform
• Build robust, customer‑facing APIs and backend components
• Develop and improve agent‑based AI orchestration pipelines
• Integrate backend services with internal systems for job scheduling, workflow execution, and task orchestration
• Work with data/context storage systems used by AI agents
• Ensure system reliability, performance, and scalability
• Collaborate closely with senior engineers and cross‑functional teams
• Participate in technical discussions and contribute to architectural decisions
• Deliver features iteratively in a fast‑paced, deadline‑driven environment
• Continuously improve code quality, system design, and development processes

• Possibility to work remotely

• Reimbursement of medical expenses
• Online morning exercise

• Compensation for trainings, seminars, conferences
• Free access to the Pluralsight and ACloud
  
  Guru knowledge base
• Access to the Altex Soft library with top‑notch materials
• A mentor for a probation period
• Engagement in our Mentorship Hub program as a mentor or a mentee to foster professional growth and development

• Horizontally — master new technologies at internal courses
• Vertically — choose your own career path through Competency trees

• All your activities are marked by points that can be exchanged for gifts to fit any taste.
