Opportunity details

About this role.

For over 30 years, Angi has powered the future of the home services industry, creating an environment where homeowners and pros benefit from more jobs done well.

For homeowners, our platform is a reliable way to find skilled pros. For pros, we’re a reliable business partner who helps them find the winnable work they want, when they want. For employees, we’re an amazing place to call home. We can’t wait to welcome you.

Angi at a glance:

  • Founded in 1995 as Angie’s List and rebranded in 2021

  • Global company with 9 brands in 8 countries and employees worldwide

  • Homeowners have turned to us for 300 million home projects and counting

About the team:

At Angi, security is woven into everything we build, from PCI-scoped payment flows to the AI agents now handling homeowner/pro conversations and scheduling end-to-end. Detection signal spans cloud, endpoint, identity, SaaS, and a growing set of autonomous agents. You’ll own detection and response as an engineering problem: build the detections, build the automation that works them, and carry the pager for what still gets through.

While this is a remote position, we are a global company and are looking for applicants located in eastern or central time zones to align with our team’s working hours.

What you’ll do:

  • Build and own detections across AWS (GuardDuty, CloudTrail, SecurityHub), EDR, identity, SaaS, and our AI gateway. Coverage, precision, and latency are properties we manage across a rule’s lifecycle.

  • Own the security log pipeline, and own it as a product with consumers: audit and security logs land centrally and are exposed to the teams that need them for triage, analysis, and incident response.

  • Own detection on the application protection layer – account takeover, credential stuffing, and abuse patterns against a two-sided marketplace.

  • Build the triage layer – enrichment, correlation, containment, evidence capture – working toward a median alert that resolves without a human touching it. Use LLM and agentic tooling where it earns its place, and own the verification layer that makes that output trustworthy.

  • Buy the tool where a tool is right, build where it isn’t, and extend where it’s close. You’ll ship code in a repo, not only configure consoles.

  • Extend detection coverage to Angi’s agentic AI products: what anomalous behavior looks like for an autonomous agent holding calendar and account access – prompt injection attempts, tool-call abuse, data exfiltration through the agent surface.

  • Actively participate in all facets of the incident response lifecycle by participating in a 24/7 on-call rotation.

  • Own the technical controls InfoSec retains for detection within compliance frameworks such as PCI DSS (tamper-detection monitoring, log integrity, alerting coverage).

  • Partner with platform and product teams so new services ship with telemetry, threat models, and response playbooks. You will be in the room when these are designed, not brought in after the fact.

Who you are:

  • You have 5+ years of experience working on a security team supporting product/engineering functions, cloud infrastructure, and corporate infrastructure development

  • You have software engineering experience (Python preferred) and an engineering mindset for building reliable / maintainable security infrastructure to support a large organization with CI/CD software engineering practices

  • You are at home in the analytics and observability stack detections get measured on – Grafana, Looker, NewRelic or similar. You will build your own coverage and precision dashboards rather than filing a ticket for them.

  • Hands-on with AWS and infrastructure-as-code (Terraform, CloudFormation, or equivalent); working knowledge of EDR, SIEM, and SOAR platforms and their APIs.

  • Hands-on with containers and Kubernetes, including what detection and forensics look like on that surface.

  • Sound build-versus-buy judgment with no allergy to either answer. You reach for what exists when it fits, and you’re comfortable wrapping, extending, or replacing it when it doesn’t.

  • You’ve owned incidents end to end – page, diagnosis, fix, postmortem.

  • Some level of exposure to LLM/agentic system security (prompt injection, agent identity, data exfiltration via AI systems).

  • A daily, fluent user of AI-assisted coding/security tools. You are able to speak concretely about how you direct and verify AI output.

  • Strong written communication: you’ll write detection documentation, postmortems, and design feedback that other engineers rely on.

  • Comfort executing the technical side of a compliance framework (PCI, SOX, or similar) is preferred.

Compensation & Benefits

  • The base salary band for this position ranges from $150,000 – $225,000, commensurate with experience and performance. Compensation may vary based on factors such as geographic location.

  • This position will be eligible for a competitive year end performance bonus & equity package.

  • Full medical, dental, vision package to fit your needs.

  • Flexible vacation policy; work hard and take time when you need it.

  • Pet discount plans & retirement plan with company match (401K).

  • The rare opportunity to work with sharp, motivated teammates solving some of the most unique challenges and changing the world.

We value diversity

We know that the best ideas come from teams where diverse points of view uncover new solutions to hard problems. We welcome and value individuals who bring diverse life experiences, educational backgrounds, cultures, and work experiences.

Our hiring process may utilize artificial intelligence (AI) tools to assist in candidate screening and assessment. Our AI tools are designed to complement, not replace, human decision-making.

Sample interview questions
How would you design a detection lifecycle that improves both coverage and alert precision?

I would define the threat scenario, data sources, expected adversary behavior, and measurable success criteria before deploying a rule. I would then validate it with historical data and controlled simulations, track alert volume, true-positive rate, investigation time, and missed detections, and regularly tune or retire rules based on those outcomes. Documentation, ownership, and response playbooks would be part of the lifecycle rather than afterthoughts.

Describe your approach to automating security-alert triage without creating unsafe containment actions.

I start with deterministic enrichment and correlation, such as asset context, identity history, recent authentication events, threat intelligence, and known-change data. Automation should assign a confidence level and preserve evidence, while containment actions require clearly defined thresholds, guardrails, reversibility, and escalation paths. I would test workflows against realistic incidents and monitor false-positive containment outcomes before expanding automated authority.

How would you detect account takeover and credential-stuffing activity in a marketplace application?

I would combine authentication telemetry, IP and device reputation, login velocity, password-reset patterns, user-agent behavior, geographic anomalies, and post-login actions. Detection logic should distinguish expected shared-network behavior from coordinated attack patterns by correlating events across accounts and time windows. I would pair alerting with graduated controls such as step-up authentication, rate limiting, session invalidation, and evidence capture.

What security concerns are most important for agentic AI systems with calendar and account access?

Key concerns include prompt injection, excessive tool permissions, confused-deputy behavior, credential exposure, unauthorized data access, and exfiltration through tool outputs. I would enforce least-privilege scoped identities, validate and log tool calls, separate trusted instructions from untrusted content, apply policy checks before sensitive actions, and build detections for unusual agent behavior. Continuous evaluation and human review for high-impact actions are essential.

Tell us about your role in a significant incident from initial alert through postmortem.

In a strong response process, I would first validate the alert, assess impact, preserve relevant evidence, and coordinate containment while keeping stakeholders informed. I would lead or support root-cause analysis, remediation, recovery validation, and clear incident documentation. After resolution, I would turn lessons learned into concrete improvements such as new detections, automation, logging changes, architectural safeguards, and an updated playbook.
