Senior Full Stack Engineer
Location: Melbourne, VIC, Sydney, NSW
Department: Engineering
Location Type: HYBRID
Employment Type: FULL_TIME
The Role
We’re looking for a Senior Software Engineer to join the Auth team — the group that owns how 70+ million people get into Linktree and stay safely signed in. Authentication is the first thing every Linker touches and the one surface that has to work every single time, across social login, email, sessions, tokens and the business-account access that sits on top of them.
You’ll work the whole path: the login and signup flows creators see, the services and APIs behind them, the session and token lifecycle, and the observability that tells us something is wrong before a Linker does. You’ll be hands-on across TypeScript, Node, React and AWS, and you’ll partner closely with Product, Security and the platform teams to decide where to harden, where to simplify, and where a small change in friction moves conversion for tens of millions of people.
This is a role for someone who likes owning a critical, unglamorous surface and making it excellent. Every improvement you ship removes a reason someone can’t get to their own digital presence — and helps Linktree achieve our mission: to empower anyone to curate and grow their digital universe.
What You’ll Own
- Build and ship the authentication and identity experiences Linkers touch first: signup, login, social auth, account recovery and multi-factor.
- Own the services behind them end-to-end — session and token lifecycle, revocation, rate limiting, and the APIs other squads depend on.
- Partner with Security to harden the auth surface, and with Product to keep friction honest so login conversion improves rather than degrades.
- Extend identity and access for business accounts and Workspaces, including the path toward SSO.
- Keep the surface observable: instrumentation, alerting and dashboards that catch auth failures before Linkers report them.
- Bring AI into how you build, and use it to move faster on migrations, tests and investigation.
- Raise the bar around you through review, pairing and documentation, and mentor engineers as the Auth team grows.
Who We’re Looking For
- 4+ years of professional software engineering experience, ideally including time on an auth, identity, platform or payments-adjacent team.
- Solid full-stack skills across our core stack: TypeScript, Node.js, React, GraphQL, PostgreSQL or MySQL and AWS, with the ability to move across layers to ship a feature end-to-end.
- Working knowledge of authentication and identity fundamentals: OAuth 2.0, OIDC, JWTs, session management, MFA and the common attack classes.
- Experience shipping changes to a high-traffic, critical path safely — feature flags, staged rollouts, migrations and backwards compatibility.
- Fluency with AI-assisted development (Claude, Cursor, Codex and similar), including how to prompt, validate and refine what these tools produce.
- A pragmatic instinct for balancing security against user experience, and the confidence to make that trade-off explicit with Product and Security.
- Clear communicator who works well with product, design and security partners across Melbourne, Sydney and other time zones.
- Able to work from our Melbourne or Sydney office on a hybrid basis.
Linktree is committed to providing a fair and competitive compensation package including cash, equity, and benefits. Final offers depend on multiple factors including location, experience, expertise, and role scope, and may vary from the range listed.
