Senior Software Engineer, Security

Engineering · New York City · Full time

About Alchemi

It takes more than a decade and over $2 billion to bring a new drug to market. Alchemi builds AI that helps drug development teams move faster, and we already work with some of the largest pharma companies and CROs in the world.

The role

We're a small, senior engineering team, and security sits at the centre of what we deliver. Our customers are some of the most regulated organisations in the world, and their security and quality teams look closely at everything we ship. You'll own how we keep the platform and our customers' data secure, and make that easy to prove.

What you'll do

• Own application and cloud security across the platform, from design review to production.
• Build and run identity and access: SSO, OAuth, tenant isolation and least-privilege access.
• Lead customer security reviews alongside our commercial team.
• Drive our compliance programmes and keep the evidence behind them current.
• Set up monitoring, incident response and secure-by-default tooling the rest of the team can rely on.

What we're looking for

• Several years as a software engineer, with real depth in security.
• Hands-on experience securing cloud infrastructure, ideally AWS, with infrastructure as code and CI/CD.
• Experience with SOC 2, ISO 27001 or similar frameworks, and comfort explaining controls to auditors and customers.
• Good judgement about risk. You know what to fix now and what can wait.
• Low ego. You listen first and work toward consensus.

Nice to have

• Experience in a regulated industry such as life sciences, healthcare or finance.
• Depth in identity protocols such as SAML and OIDC.

How we work

Small team, low process, high trust. Two-week release cadence, design specs reviewed carefully, and an active resistance to ticket sprawl. Based in New York City, with daily overlap across a team that spans Pacific Time to Western Europe.

Why join

Our goal is to cut years off clinical development timelines. Alchemi already supports more than 3,500 studies a year for the top development teams in pharma. We're a small team of experts. We keep talent density high and work closely across every part of the product, from first idea to deployment.

• Impact: Your work goes straight into the regulated workflows that decide how fast drugs reach patients.
• Excellence: Work alongside a highly skilled team in a fast-paced, high-impact environment.
• Ownership: Help shape product direction, how we work and what we build next.

What we offer

• Salary and equity: Competitive salary and meaningful equity, with options weighted toward ownership if that's what you want.
• Health: Best-in-class health and dental insurance.
• Time off: 4 weeks of paid vacation plus public holidays, paid sick leave and parental leave.
• Location: Based in New York City.
• Equipment: A MacBook, external monitor and accessories.
• Growth: Room to learn and develop in a cutting-edge field.
