About the role
Anthropic is seeking a Software Engineer to join the team building Claude Security. You will ship user-facing and backend features, spanning from prototypes to production, working across the full stack. You'll collaborate with researchers, product managers, and go-to-market teams to shape the roadmap, own significant pieces of work, and balance ambitious security capabilities with practical product delivery.
Before you apply
Applying takes about a minute. These four things decide how fast it moves after that.
Your profile is current
It's what we read first. Occupations, seniority and locations matter more than a long history.
Two examples you can talk through
Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.
A number in mind
What you're on now and what would make you move. We negotiate better when we know both.
Your notice period
Employers plan around it, and it's the question that stalls offers most often.
Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
