Role to design and implement security architecture patterns for AI tooling: convert security standards into machine-enforceable formats, build evaluation and verification workflows for generated code, maintain reference implementations (templates, Helm charts, container images), and elevate prototypes to production with reliability, observability, and access controls. Requires 8+ years in security/platform/DevSecOps or software engineering for large distributed systems and proficiency with cloud-native tooling (Kubernetes, Helm), Python or Go, CI/CD, policy-as-code, and threat modeling.

Build and operate docs-as-code systems (Git, CI/CD, static site generators), automate content lifecycle with Python and LLMs, make documentation AI-ready (RAG, agent context kits), encode standards into templates and validators, and partner with engineering and product teams. Requires 8+ years in technical writing/developer documentation and hands-on experience with docs-as-code, Python, and applying LLMs to content workflows.

Hybrid engineering/security role within xStocks responsible for end-to-end security deliverables: coordinating and reviewing smart-contract audits, running offensive assessments (web, API, backend, on-chain), threat-modeling systems, reviewing code for auth/crypto/custody changes, hardening secrets/IAM/dependencies, securing signing and custody integrations (HSM/MPC), supporting incidents and remediation, and developing automation and tooling. Requires strong application and infrastructure security fundamentals, hands-on offensive experience, applied cryptography and blockchain security knowledge, and ability to write/review production TypeScript/Node.js code.

Join the CF Benchmarks Index Team as a Java backend developer to implement new financial benchmarks, develop end-to-end features, contribute to data analysis, core infrastructure and business logic, and support a 24/7 real-time distributed system. Requires strong Java and backend development experience and a minimum of 3 years of relevant experience. Familiarity with CI/CD, Git, SQL, protobuf/RPC, message queues, and Redis is desirable.

Fingerprint seeks a hands-on Staff Application Security Engineer to found the AppSec engineering function: design and operate a secure SDLC, own SAST/DAST/SCA/secrets/container/IaC scanning in CI/CD, run vulnerability management and pen-test/bounty remediation, perform manual app-layer testing and incident response, build AI-assisted security tooling, and enable engineering via training and reviews. Requires 8+ years in software/security engineering with deep AppSec expertise.

Karat is hiring a Community Engineer (SWE3) to be the sole engineer for the Brilliant Black Minds program, spending ~70% on hands-on engineering and ~30% on community program management. Responsibilities include building scalable services, integrating LLM APIs, creating automations (newsletters, Discord integrations), and managing day-to-day community operations. Requires 5+ years' experience building web applications or distributed systems and familiarity with cloud platforms and LLM/AI integrations. Position is remote but limited to specified U.S. states; immigration sponsorship is not available.

Join the Vulnerability Management Engineering team to design, build, and operate systems that collect security findings from code, containers, hosts and cloud, match findings to owning teams, enforce software supply chain controls, and track remediation and compliance (e.g., FedRAMP). Role involves backend/distributed systems development, cloud and container work, on-call participation, technical leadership, and cross-functional collaboration.

Join CircleCI's On-Prem team to own the technical direction for tooling, test infrastructure, and release automation for CircleCI Server. The role requires deep Kubernetes and Helm experience, strong backend and systems skills (Go), 8+ years of experience building production infrastructure and distributed systems, and expertise in observability (OpenTelemetry), release processes, and operator-focused diagnostics.
