As a Software Engineer IV, you will work closely with the team's senior engineers, Product Managers, and Designers. You’ll also collaborate closely with our Pune in-office Customer Operations team and teams in the Netherlands and North America to solve real-world problems for our global customers.
In this role, you will lead complex initiatives and own end-to-end delivery of projects with moderate to large scope. You anticipate delivery risks, align stakeholders early, and maintain quality under tight timelines. Together with the Senior Engineering Manager, you will develop excellent capabilities to serve your customers by combining technical depth with operational discipline, balancing scope, risk, and speed, and surfacing trade-offs to enable informed decisions.
HackerOne is investing in a CTEM roadmap that includes agentic work. You will help drive the design and delivery of AI-assisted and agentic capabilities that are measurable, safe to operate, and tied to customer outcomes. You will also raise the bar for platform health and influence HackerOne’s engineering practices to accelerate execution.
You’ll combine your technological expertise, domain knowledge, and an unquestionable dedication to business objectives as you intersect with the engineering organisation. You identify and make systematic improvements to technical weaknesses you’ll find in your squad’s codebases, and in shared codebases across the company.
Your first month will be spent getting to know our company and your fellow HackerOnies through our well-organised and fun onboarding process called H.A.T.C.H.
You will set up your development environment, get a feel for our engineering processes, and embark on a journey to fully understand the domain you will be working with.
By day 30, you will have met most of your fellow Engineering HackerOnies, paired with other Software Engineers, developed a strong understanding of our codebases and Security Management products, and be prepared to start hands-on coding.
By day 60, you will be involved in building a meaningful part of one of the projects and will have become more connected with our community and various stakeholders.
By day 90, you’ll have impressed your colleagues with your technical contributions and earned trust and credibility within your squad and the whole Engineering team by presenting your progress during our review/demo sessions.
Lead complex initiatives as a project lead together with stakeholders, designers and product leaders
Build, ship and maintain highly available, performant and durable features, focused on (but not limited to) hacker-facing areas of our platform

Be a part of cross-squad initiatives and influence shared engineering practices to accelerate execution across teams
Onboard, guide, mentor, and delegate effectively to engineers; build leverage by creating clarity, reusable patterns, and strong technical direction
Lead CTEM and agentic work, including:
Owning architecture for agentic workflows (tool use/function calling, orchestration, retrieval/RAG, human-in-the-loop patterns)
Building and introducing AI tools that improve delivery efficiency and reduce repetitive work; challenging legacy solutions that slow velocity
Proactively leading adaptation during change: re-scoping tasks during direction pivots, aligning with Product, and surfacing trade-offs clearly to move decisions forward
Implementing data loops that enable continuous optimisation (quality metrics, capacity/latency/cost trade-offs, velocity signals, and post-launch monitoring)
At first, a tech-savvy person who likes to work with people and teams
Willing to learn from Senior and Staff Software Engineers
Owner of your progress as an individual
You bring 8+ years of software development experience within a modern SaaS environment
