Belgrade, Central Serbia Wallarm Full time €40,000 - €80,000 per year

Since 2016, Wallarm has been on a mission to secure the internet's critical infrastructure: APIs. Today, we are the trusted choice for over 200 of the world's most innovative companies, from high-growth startups to Fortune 500 and Nasdaq leaders. Our unified platform provides full-lifecycle API security — helping teams discover their attack surface, protect against modern threats, and respond to incidents in real-time. As a graduate of Y Combinator and fueled by a recent $55M Series C, we are scaling our global, remote-first team of 150+ innovators to solve the next generation of security challenges.

About this opportunity:

We are looking for a highly adaptable and curious Go Intergration Engineer to join our Node team. In this role, you will be responsible for building and maintaining "connectors" —the critical bridges that allow third-party applications to send analysis requests to our core platform (node). The real challenge lies in research, analysis, and language versatility. You must be comfortable diving into unfamiliar documentation, evaluating the best path for an integration, and then writing clean, testable code in diversity.

What you'll do:

  • Research & Discovery: Dive deep into the technical documentation of new third-party services to understand their integration capabilities. You'll identify how we can intercept workflows, modify requests, send data to our node, receive a response, and block transactions.

  • Solution Analysis: When multiple integration options exist, you will analyze them based on key criteria (e.g., performance latency, security, ease of setup for the customer) and recommend the best path forward.

  • Development: Write the core connector code. You must be agile enough to switch contexts and languages as needed.

  • Testing: Develop tests for new connectors and take ownership of debugging and resolving issues when existing tests fail.

  • Documentation: Author clear, detailed, and user-friendly setup instructions for our customers to ensure they can configure the connector smoothly.


We're looking for a candidate with:

  • Proven experience in a software engineering role for 3+ years.

  • Practical experience with Golang.

  • Experience reading and integrating with third-party APIs and services.

  • Demonstrable experience learning and building projects in multiple, varied programming languages (e.g., experience with a mix of languages like JS, Rust, Java, Python, Go, etc.).

  • Strong knowledge of web fundamentals and API protocols, particularly REST, gRPC, SOAP and HTTP (headers, request/response cycles).

  • Knowledge of network infrastructure and protocols.

  • Experience with software testing (unit, integration).

What we offer:

  • Completely remote work and flexible working hours

  • Competitive salary and bonuses

  • Paid days off

  • Medical insurance

  • Working equipment

  • Professional development and career growth
