Job description

Snyk is the leader in secure AI software development, helping millions of developers develop fast and stay secure as AI transforms how software is built. Our AI-native Developer Security Platform integrates seamlessly into development and security workflows, making it easy to find, fix, and prevent vulnerabilities — from code and dependencies to containers and cloud.

Our mission is to empower every developer to innovate securely in the AI era — boosting productivity while reducing business risk. We’re not your average security company - we build Snyk on One Team, Care Deeply, Customer Centric, and Forward Thinking.

It’s how we stay driven, supportive, and always one step ahead as AI reshapes our world.

Why this role?

As a Senior Software Engineer, you’ll play a key role in shaping how modern organizations build and secure software at scale. You’ll join a collaborative, forward-thinking team and help drive our mission to embed security into every part of the AI-native development lifecycle.

As a part of our teams you’ll have the opportunity to make an impact on a wide range of projects, from mastering existing services to building new, cutting-edge features. Your contributions will directly impact the success of our products and the security of millions of developers worldwide.

As a Senior Software Engineer at Snyk you will play a significant role in shaping the technology of Snyk. You will drive consensus with other engineers to build foundational infrastructure at scale, and work with others to ensure it is used broadly and consistently.

Within Team Access, part of the broader Platform Division, you will play a crucial role in helping shape the future of our Authentication, Authorization and Auditing (AAA) stack. You\'ll achieve this by maintaining and continuously improving the critical systems that deal with the vast majority of our internal and external requests, and drive the improvement of our CDN stack.

You’ll Spend Your Time:

• Developing and maintaining Infrastructure as Code (IaC) solutions for GCP Loadbalancers, Akamai and other public internet-facing applications, utilizing Terraform and Helm.
• Configure, deploy, and manage high-throughput, high-availability, low-latency applications that are critical to Snyk’s uptime.
• Crafting and architecting complex solutions for our increasingly distributed system.
• Coding mainly Go, and occasionally in TypeScript, deploying solutions in a CI/CD workflow.
• Analyzing, designing and implementing high-quality solutions to problems with well-tested, maintainable code.
• Building systems with the long-term in mind, focusing on good design, robust testing, and sustainability from the perspective of cost and scale.
• Supporting our customers by resolving bugs and customer support escalations.
• Designing solutions to problems which typically require multiple engineers to implement.
• Demonstrating end-to-end ownership for the delivery of key efforts, and leading peers in the delivery of particularly broad efforts as a technical lead.
• Providing mentorship to more junior engineers, and playing a role in growing the next generation of engineers at Snyk.

What You’ll Need:

• At least 5 years of commercial experience as a Software Engineer.
• Experience in large-scale software systems design, and familiarity with fundamental computer science concepts (algorithms, complexity, data structures).
• Proficiency in at least one of our core programming languages (ideally Go), and a willingness and enthusiasm for learning new languages and technologies.
• Experience working with industry standard encryption algorithms, and an understanding of how to manage a zero-trust system.
• Familiarity with distributed system architectural challenges.
• A track record of successfully developing systems capable of handling substantial throughput.
• Building highly reliable, scalable microservice back-ends for web APIs or applications, or other types of large-scale, high reliability systems.
• Building infrastructure or platform automation, or observability or release tools.
• Demonstrable skill in effective software testing.
• Strong commitment to code quality, and the value of giving and receiving feedback through code reviews.
• Ability to deal with ambiguity, and respond with agility when requirements and priorities change.
• Effective communicator both verbally and in writing. Able to work collaboratively, be curious and have a growth mindset.
• Ability to lift the performance of a team through coaching and mentoring of more junior engineers.

We’d be Lucky if You:

• Have experience with and understand how Envoy, Istio, and their filter-chains work.
• Have production-grade experience with Kubernetes or have worked with any of the popular cloud platform offerings from Google, Amazon, and Microsoft Azure.
• Enjoy working on early stage products; to identify, prioritize and solve problems iteratively and build something that our internal/external stakeholders really love.
• Feed off complex technical problems and find solutions where others see roadblocks.
• Embrace challenges and learn from them.

We care deeply about the warm, inclusive environment we’ve created and we value diversity – we welcome applications from those typically underrepresented in tech. If you like the sound of this role but are not totally sure whether you’re the right person, do apply anyway!
