Backend Tech Lead / Software Architect (Backend & APIs)

Why this role?

We’re looking for a hands-on, technically strong Architect who enjoys designing real systems, working closely with engineering teams, and shaping solutions end-to-end - from discovery to delivery.

This is not a corporate governance role. It’s a practical, problem-solving position for someone who wants real architectural ownership, technical influence, and direct impact on projects.

What you’ll be doing

• Designing and evolving backend and API architectures (Cloud & On-Premise)

• Creating scalable, maintainable systems with clear trade-offs

• Designing public and internal APIs (REST, GraphQL, async/event-based)

  • versioning, contracts, backward compatibility

• Participating in technical & business discovery with clients (together with Sales)

• Supporting delivery teams in solving complex backend challenges

• Setting and improving engineering standards, tooling and best practices

• Writing architecture & technical documentation (design docs, proposals)

• Collaborating directly with clients and stakeholders

• Actively experimenting with and applying AI-powered tools (LLMs, copilots, internal agents) to improve developer productivity and system capabilities

Our typical tech stack (varies by project)

Backend & APIs

• Java / Kotlin

• Node.js / TypeScript

• REST, GraphQL, event-driven architectures

Cloud & Infrastructure

• AWS / Azure / GCP

• Docker, Kubernetes

• Serverless & container-based solutions

Data

• SQL & NoSQL databases

• Event streaming

DevOps & Quality

• CI/CD pipelines

• Infrastructure as Code

• Monitoring & observability

We don’t expect you to know everything - but we do expect strong architectural thinking and hands-on experience with modern backend systems.

Must have

• 7+ years of professional experience in software engineering

• Proven ability to lead architectural discussions and make pragmatic technical decisions

• Hands-on experience designing and implementing backend systems and APIs

• Strong experience working directly with clients

• Ability to clearly explain complex technical concepts to non-technical stakeholders

• Ownership mindset - from prototyping to strategic architectural direction

• Comfort working with modern AI concepts (LLMs, embeddings, RAG, streaming responses)

• Excellent English (min. C1)

Nice to have

• Experience with SQL and/or NoSQL databases

• Authentication & authorization (JWT, OAuth2, OIDC)

• Experience with multiple cloud providers (AWS, Azure, GCP)

• DevOps mindset and CI/CD experience

What we offer

• Remote-first approach (or hybrid / office - your choice)

• Flexible working hours

• B2B

• Full-time cooperation

• Projects with real technical ownership

• Impact on architectural decisions across projects

• A mature engineering culture focused on quality and pragmatism

If you’re a technically-driven architect who enjoys building real systems and working closely with teams, we’d love to talk.
