Senior Backend Engineer

DuckDuckGo is currently seeking a highly skilled Senior Backend Engineer to join their global, remote-first team. As an organisation that has carved out a unique space in the tech landscape by prioritising user privacy and digital trust, they are looking for someone who can contribute to their diverse suite of products, including their widely used browser, search engine, and subscription services. With a history of stability dating back to 2008 and a team of over 400 professionals, this role offers an opportunity to work at the intersection of high-scale engineering and consumer-facing privacy solutions.

About the role

This is a senior-level position designed for an engineer who thrives in environments where ownership and accountability are paramount. DuckDuckGo operates on a culture of empowered project management, meaning that you will not just be writing code, but actively shaping the direction of company-wide objectives. You will be expected to work independently while collaborating effectively with a distributed team. The role focuses on delivering high-quality, performant, and testable code while maintaining a pragmatic approach to technical debt and system architecture.

Beyond the technical execution, you will play a crucial part in the development of the engineering team. Mentorship is a core expectation, as the company values the growth and development of its staff. You will be helping to foster a culture of inclusivity and transparency, ensuring that as the company grows, the engineering standards and team dynamics remain robust.

Your daily responsibilities will involve a mix of deep-focus engineering and high-level project leadership. You will be tackling complex problems that span across the organisation’s various platforms, ensuring that their systems—ranging from their search infrastructure to their latest AI agent tools—are reliable and efficient.

Specific responsibilities include:

• Leading large-scale projects that align with the company's primary strategic goals.
• Developing and maintaining performant backend systems primarily using Go, Node.js, and Perl.
• Engaging in peer collaboration to resolve technical challenges and product-related hurdles.
• Driving the mentorship of junior and mid-level engineers to facilitate their career development.
• Exercising strong technical judgement to make informed trade-offs between speed, scalability, and security.

What they're looking for

DuckDuckGo is seeking candidates who possess a deep reservoir of experience. You should be someone who understands not just how to build systems, but how to build them in a way that respects the end user’s privacy while delivering a top-tier product experience.

Key requirements include:

• Over seven years of professional experience in backend software development.
• Proficiency in navigating complex data structures and backend architectures.
• Experience or strong familiarity with modern AI agent tooling.
• Proven ability to lead projects from conception to deployment with minimal oversight.
• Exceptional communication skills, essential for a fully remote team environment.
• A track record of mentoring team members and contributing to team health.

For a South African software engineer, a role with an international, remote-first organisation like DuckDuckGo represents a significant career milestone. Roles of this calibre—specifically those requiring 7+ years of experience and senior-level architectural responsibilities—often command market-leading salaries in USD, which are highly competitive in the South African market. Working remotely for an organisation of this size usually allows for flexible working hours, which is a major advantage for those balancing the local time zone with a global team. Such positions are excellent for engineers looking to move away from local corporate structures and into high-impact, product-led environments where they can influence global digital privacy standards.

• 7+ years of professional experience focused on backend systems.
• Product acumen to reason about technical tradeoffs.
• Familiarity with AI agent tooling and complex data structures.
• Solid project management abilities and excellent communication skills.
• Previous experience leading and mentoring other engineers.
