Software Engineer, Backend
The backend developer will own major feature development and work directly with founders on product development from end to end. Responsibilities include working with a small interdisciplinary team across hardware, software, and design to build new products from scratch; building new features and designing new architecture to address challenging problems; building backend infrastructure to perform scalable training in the cloud; rethinking and refactoring existing codebases for scale; and continuously improving and maintaining code in production. The role involves full ownership throughout the entire product lifecycle, including idea generation, design, prototyping, execution, and shipping, contributing to multiple parts of the codebase in various programming languages.
Software Engineer, Codex Runtime
The responsibilities include shaping the evolution of Codex by identifying how teams use and break AI-powered software engineering, driving changes across product, infrastructure, and model behavior to improve reliability. Building core team and enterprise primitives to enable Codex usability at scale, such as container orchestration, virtual machine provisioning/configuration, execution sandboxes, shared block storage, RBAC, admin and audit surfaces, usage and pricing controls, managed configuration and constraints, and analytics for visibility into Codex usage. Designing and owning secure, observable, full-stack systems that power Codex across web, IDEs, CLI, and CI/CD, integrating with enterprise identity and governance systems (SSO/SAML/OIDC, SCIM, policy enforcement), and developing data-access patterns that are performant, compliant, and trustworthy. Leading real-world deployments and launches by working with customers and go-to-market teams to roll out Codex across teams, using live usage and operational signals to iterate and improve the product and platform based on real-world feedback.
Principal Software Architect
As a Principal Software Architect at HackerOne, you will define and evolve the architectural vision for the HackerOne Platform and core systems to ensure scalability, reliability, and performance. You will partner with Product, Platform, and Security teams to translate long-term business and product goals into actionable architectural strategies. You will collaborate with Principal and Distinguished Engineers to align on technical direction, establish shared standards, and evolve system design principles. Your role involves leading major cross-team initiatives to modernize architecture, improve observability, and reduce complexity. You will mentor and guide engineering teams to foster technical excellence, knowledge sharing, and continuous improvement. You will evaluate and integrate emerging technologies including AI, GenAI, and LLM-driven architectures to enhance platform intelligence. Additionally, you will drive architectural governance and documentation to ensure maintainability and transparency and communicate architectural direction clearly to technical and non-technical stakeholders. Within the first 30-90 days, you will move from understanding systems and architecture to leading architectural initiatives that impact teams company-wide.
Freelance Software Developer (Kotlin) - AI Trainer
As an AI Tutor in Coding specializing in Kotlin development, the responsibilities include designing high-quality technical content, examples, and explanations demonstrating best practices in Kotlin development; collaborating with engineers to ensure accuracy and consistency across code samples, tutorials, and developer guides; exploring modern Kotlin frameworks and tools to create practical, real-world examples for learning and testing; and continuously refining content based on feedback, emerging patterns, and advances in the Kotlin ecosystem. The role also involves contributing to projects aligned with skills by creating training prompts and refining model responses to help shape the future of AI while ensuring technology benefits everyone.
