About the Company

Stealth-mode company specializing in data-driven technology solutions for the market research industry.

Their core product is a survey data platform powered by a custom-built engine written entirely in C++. The platform is actively evolving and requires continuous feature development and integrations to meet growing client needs.

Team Setup

• Core Architect — responsible for the engine and architectural decisions.
• Frontend Developer — React/JS and supporting backend tasks.
• Distributed team based in Europe.

Role Overview

We are looking for an experienced Senior C++ Developer (5–6+ years) to join the team and strengthen the development of the platform’s core engine.

The role involves extending a domain-specific language (DSL), building XML-based integrations, and ensuring smooth deployment of new features into production.

This is a full-time contract role with technical management handled directly by the client.

Responsibilities

• Enhance and extend the core system engine written in C++.
• Implement new question types in the internal DSL and data formats.
• Generate and validate XML for integrations with external survey platforms.
• Support and refine existing integrations to ensure compatibility with external systems.
• Participate in migrating new features from test environments into production.
• Collaborate closely with the system architect and distributed team members.

Must-Have Requirements

• 5–6+ years of professional experience with C++.
• Background in engines, compilers, or domain-specific languages (DSLs).
• Strong understanding of XML (generation, parsing, integration).
• Experience with databases.
• Familiarity with CI/CD pipelines and Git-based workflows.
• Ability to work effectively in a distributed team environment.

Nice to Have

• Experience in survey data or market research technology.
• Basic knowledge of React/JavaScript frontend development (not required, but useful).

Logistics

• Engagement: Full-time, long-term contract.
• Start date: October.
• Location: Preference for candidates based in Europe (due to occasional in-person meetings in Rotterdam).
• Travel: Infrequent, but candidates must be open to occasional trips.
• Duration: Initial 6 months with potential for extension.
