Senior Backend Engineer

At Scanner, we’re committed to building the best tools in the world (in Rust!) for teams to search and query through enormous piles of data. Whether you're debugging a distributed system, or monitoring a sprawling backend deployment for security risks, so many problems that modern engineering teams face are ultimately about sifting through giant haystacks in search of small but valuable needles. Scanner provides a magical user experience with ⚡ fast queries, allowing teams to manage massive data sets with far more ease than they can with existing tools.

We believe Data Lakes are the future of security data. Scanner is the world's fastest full-text search and detection platform for Security Data Lakes.

Security teams can now search years and petabytes of logs in seconds (up to 700x faster than alternatives), eliminate SIEM coverage blind spots at 70-80% lower cost, and deploy in a day—all while maintaining full custody of their data in their own S3 buckets.

We believe security tools should scale with your data, not your budget. Teams shouldn't have to choose between comprehensive coverage and financial sustainability.

We're an early-stage team where every person has outsized impact on what we build and how we serve customers.

People join Scanner because they want to:

• Solve genuinely hard technical problems - Making petabyte-scale search feel instant requires deep systems thinking and novel approaches.
• Work pragmatically and move fast - We ship quality products quickly by focusing on what actually matters to customers.
• Have direct impact - Talk to users, shape product direction, and see your work make a difference immediately

We're builders focused on creating genuinely transformative tools for security teams dealing with massive data challenges.

We're looking for a Senior Backend Engineer to join our team to create high quality products with great UX in record time. A strong candidate will have:

• Specific familiarity in one or more systems languages like Rust, C/C++, GO, and/or Swift.
• General familiarity with databases, database internals, distributed systems, data pipelines/warehouses.
• Comfort working in a fast-paced and low process environment.
• A minimum of 7 years of professional experience in software development, with an emphasis on backend technologies.

Talented engineers can pick up new languages and frameworks quickly. Here’s what our tech stack looks like today, but if you come with a better way of doing things we’re flexible and committed to building the best tools for our customers no matter what!

• We use Rust throughout the backend, giving us extremely fast performance with strong security guarantees.
• Our frontend is written using Svelte and TypeScript.
• Our query system leverages highly burstable compute provided by serverless components like Amazon Lambdas.
• We use S3 to store logs at scale and MySQL to store metadata.
• Our log ingestion pipeline runs in Amazon Elastic Container Service (ECS)
• We use infrastructure-as-code tools like Pulumi to manage our deployments and cloud infrastructure.

• Impact & ownership: Join a small, high-trust team where your work directly impacts our users.
• Ambitious product: We solve hard problems with massive scale log search, threat hunting, and observability for cloud-native infrastructure.
• Fast-paced team & culture: We’re lean, collaborative and high-velocity.
• Growth & autonomy: We trust you to take major ownership, give you the space to grow, and we’ll support your professional development.
