Position Title: Senior/Staff Backend Engineer, Security

Position Overview:

As Redo grows across multiple products, we're investing in shared security infrastructure that the whole engineering org builds on. You'll be a software engineer who designs and builds the services, libraries and middleware that make the secure path the easy path. Engineers across every Redo product should be able to build quickly and securely by default.

You'll own problems from start to finish: understand what engineers need, design the solution, build it, run it in production, and bring the rest of engineering along. The role comes with a lot of autonomy and real influence on how Redo builds software.

What You'll Work On:

Areas this team builds in include:

Identity, authentication and session management

Authorization, API keys and secrets management

Encryption, tokenization and key management

Security audit logging, rate limiting and abuse prevention

What You'll Do:

Design, build, test, deploy and operate production backend services and libraries in TypeScript

Build shared security platforms and patterns that engineering teams across Redo adopt

Own your services in production, including monitoring, alerting and reliability

Build guardrails such as shared components, CI checks and secure defaults that help engineers ship securely without slowing down

Partner with engineering teams across the company and help raise the security bar

Mentor engineers and give technical leadership on secure design

Required Qualifications:

BS degree in Computer Science or a related technical field, or equivalent experience

6+ years of professional software engineering experience, mostly backend

Strong TypeScript and Node.js skills

Experience designing and shipping internal libraries, middleware, SDKs or platform APIs that other engineers depend on

Ownership of production services end to end, including monitoring, alerting and reliability

A solid grasp of security fundamentals (authentication, authorization, cryptography basics, common web vulnerabilities) and a real interest in building secure systems

Ability to take an ambiguous problem, design the solution yourself and see it through without step-by-step direction

Collaborative and low-ego, with the ability to influence engineers who don't report to you

Preferred Qualifications:

Has built identity, authentication, session, or encryption/key management systems

Experience with AWS IAM and KMS

Experience with e-commerce platforms

Platform or developer-experience work: building a "golden path" other teams follow

Experience at a fast-growing startup, building systems from the ground up

Benefits & Perks

On-site gym with showers, pickleball and basketball

Flexible PTO and company holidays

Company HSA contributions

Weekly lunches and a stocked break room

$100 monthly babysitting reimbursement

Monthly "Redo perks" allowance for e-commerce purchases

Close to biking and running trails
