## Description

**Mid-level BE Developer****What would you work on:**

- Deliver complete features end-to-end, from technical breakdown to production, in a microservices platform that handles tens of thousands of requests per minute.
- Design your solutions within our existing architecture. You decide how a feature fits together, and you bring in a Senior when the design crosses module boundaries.
- Work on real problems of scale: concurrency, high-volume traffic, and availability.
- Co-own the health of the services you work in: tests, observability, and the production issues that come with them.
- Use AI coding tools as part of your daily workflow, and own the correctness, security, and performance of what they produce.
- Review PRs from peers and Juniors, and mentor Juniors informally through pairing and code review feedback.
- Break down work, estimate it, and deliver on your commitments.
- Be part of a collaborative, autonomous product team in a fast-paced startup environment with no heavy process.

**Skills you will need:**

- 2+ years of professional experience with Golang (or 3+ years of backend experience with at least 1 year in Go).
- A working grasp of how architecture actually works. You do not need to be an architect, but you should be able to look at a design and tell whether it is good or bad, explain why, and make sound decisions inside your own modules. For the bigger calls, you know when to pull a Senior in rather than guess.
- Practical experience with concurrent and event-driven systems: goroutines and channels, race conditions, retries, idempotency.
- Working knowledge of distributed systems and cloud computing principles.
- Experience building microservices using SQL and NoSQL databases, such as PostgreSQL, Redis, and DynamoDB.
- Familiarity with API design patterns like gRPC or GraphQL.
- Experience running and operating your own code in production on AWS, Azure, or GCP.
- Comfortable with Docker; knowledge of Terraform is a plus.
- You write and maintain unit and integration tests as part of delivering a feature, not as an afterthought.
- Familiarity with Agile development practices.
- Interest in esports or traditional sports (a plus!).

**Working with AI, required:**

We build with AI assistance daily, and we expect you to as well. This is not a “nice to have” line on our list.

- **Hands-on experience** with AI coding assistants (Claude / Claude Code, OpenAI Codex, Cursor, GitHub Copilot, or equivalent), and a clear point of view on where they help and where they get in the way. Using them daily on a production codebase is a strong plus.
- **You can steer the tools.** You break work into reviewable steps, give the model the context it actually needs (specs, existing code, constraints), and iterate instead of accepting the first answer.
- **You know when not to use them.** Some problems are faster and safer written by hand, and you can tell which is which.
- **You review AI output like you would review a colleague’s PR**, verifying edge cases, concurrency behaviour, security implications, and performance. You catch hallucinated APIs, outdated patterns, and code that looks plausible but is subtly wrong.
- **You own what you merge**, regardless of what generated it. “The model wrote it” is not an explanation for a production incident.
- **You know the boundaries:** what can and cannot be shared with an external model, secrets hygiene, and licensing of generated code.
- **You share what works.** Effective prompts, patterns, and pitfalls that make the rest of the team faster.

Nice to have: experience with agentic workflows, MCP servers, or building internal tooling on top of AI models.

**What we are not asking from you:**

- Owning cross-team architecture or being the final technical authority. That is what our Seniors are here for.
- Designing the platform from scratch. You will work within an architecture that exists, and improve it where it makes sense.
