Security & Backend Engineer
Indexed description
As a Security & Backend Engineer, you will own core pieces of our Scala + Python backend while raising the bar on how we protect data, systems, and customers. You will design and build backend services, shape secure-by-default patterns, and lead practical security work across authentication, authorization, data protection, and infrastructure. This is a role for someone who enjoys hard backend problems and has a meaningful security background, but does not want a purely specialized security seat.
What You’ll Do
- Design and ship reliable, scalable services with senior engineers
- Work on data pipelines from ingestion to enrichment to delivery
- Build and operate backend services and APIs that power the core product
- Embed secure-by-default patterns in services, data flows, and infrastructure
- Identify risks early in product design and propose pragmatic solutions
- Guide the engineering team toward secure defaults in code, infrastructure, and workflows
- Harden cloud environments, networks, and services to reduce the attack surface
- Work with ML and data teams on secure handling of models and data
- Partner with customers to ensure their integrations with our platform are safe and seamless
- 5+ years building and operating production backend systems
- Owned security-sensitive systems (auth, permissions, secrets, data access controls)
- Strong skills in Python or Scala, ideally both over time
- Applied secure practices across data, code, and infrastructure
- Comfortable with modern cloud deployments and IaC
- Hands-on with security reviews, threat modeling, and hardening
- Enjoy balancing new feature delivery with long-term hardening and scale
- Thrive without heavy process or QA buffers and own what you ship
- Motivated by real user impact and keeping critical systems safe
- Join a no-politics, high-trust, low-ego, high-talent team
- Own backend and security work on mission-critical systems
- Work directly with founders and the Head of Engineering
- High autonomy, clear ownership, and visible impact from day one
- Operate at the intersection of AI, data, security, and enterprise workflows
- Top-tier compensation with meaningful equity upside
- Help shape our security posture, patterns, and engineering culture
Our process is fast, structured, and transparent – built to respect your time and surface real mutual fit
