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.

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. The team is small and the surface is not: cloud infrastructure, applications, and a growing set of agentic AI products. You'll own security architecture and execution across all three.
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:
Own security initiatives end to end across cloud infrastructure hardening and application security, including work that spans several sprints and arrives ambiguous.
Own the technical controls that InfoSec retains within compliance frameworks such as PCI DSS (e.g., ASV scanning, network security control reviews, tamper-detection monitoring).
Deploy and tune the infrastructure protecting Angi's applications from exploitation, account takeover, and denial of service.
Drive security architecture and threat modeling for Angi's AI agent products (voice/chat agents with calendar and account access).
Review RFCs, PRDs, and MRs from a security lens, and partner directly with product/engineering teams shipping AI-native features. You will be in the room when these are designed, not brought in after the fact.
Build the tooling and frameworks that make the secure path the easy path for Angi's engineers - paved roads, not policy documents.
Mentor engineers within and across teams, and improve the status quo where you find it - recurring incident patterns, tooling gaps, process debt.
Actively participate in all facets of the incident response lifecycle by participating in a 24/7 on-call rotation.
Continuously evaluate and integrate AI-driven tooling into InfoSec's own workflows. You're expected to use AI coding/security assistants daily, not just secure them for others.
Who you are:
5+ years in security engineering, spanning at least two of: application security, cloud/infrastructure security, or enterprise security.
Hands-on with AWS and infrastructure-as-code (Terraform, CloudFormation, or equivalent); comfortable reading and contributing to product service code (Kotlin, NextJS, Python, Ruby, Scala, or Swift are preferred).
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.
Fluent in the OWASP Top 10 and how each is actually remediated, and in the authentication and authorization standards Angi runs on (OAuth, OIDC, SAML).
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 threat models and give written feedback on other people's design docs and merge requests regularly.
Comfort executing the technical side of a compliance framework (PCI, SOX, or similar) - vulnerability scanning, control reviews, tamper detection is preferred.
Hands-on experience in the tool categories this work runs through - static analysis (Snyk, Veracode, Fortify), infrastructure vulnerability scanning (Qualys, Tenable, Rapid7), and penetration testing tooling (BurpSuite, OWASP ZAP) is preferred.
Container and Kubernetes experience 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.

Know your rights as a candidate and an employee:
The job is in Denver, CO. Below is what the official statistics say about living and working there.
How Denver compares. Among the 80 largest places in Colorado, Denver is #1 by population, #76 for homeownership (#1 = highest), #21 for remote work (#1 = most), #27 for college degrees (#1 = most). Its county, Denver County, is #2 of 64 counties for average pay ($101,834).
Denver has 718,877 residents (ACS 2020–2024), about 12.3% of the population of Colorado. It covers 153 square miles of land, which works out to roughly 4,696 people per square mile. The median age is 35.3, 6% younger than the state median (35.3 against 37.7).
The median gross rent is $1,831 a month (rent plus utilities), 4% above the state median ($1,831 against $1,761). Over a year that is 23.2% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $616,000, which is 6.5 times the median household income ($94,718); a ratio above 5 usually means buying is out of reach without savings or a second income. 48.8% of households own their home, 26% below the state average (48.8% against 66.2%). A low ownership share points to a rental-heavy market with more apartments and shorter stays.
The Denver-Aurora-Centennial, CO metropolitan area has 1,609,350 jobs in the BLS wage survey, and the median pay across all occupations is $62,320 a year, 22% above the national median ($62,320 against $50,980). The biggest occupation groups are business and financial operations (169,260 jobs, median $96,450); office and administrative support (168,520 jobs, median $53,050); sales and related (165,560 jobs, median $49,730). The area is most specialised in architecture and engineering (1.6 times) and computer and mathematical (1.6 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($160,810) and legal ($132,690). In 2026M09 the unemployment rate of Denver County was 4.4%. 74.2% of residents aged 16 and over are in the labour force. The city lies in Denver County; its jobs, pay by industry and GDP are on the county page.
Among workers, 56.1% drive alone, 3.8% use public transit, 3.6% walk, 27.3% work from home. 11.0% of workers commute 45 minutes or more, 22% below the state average (11.0% against 14.1%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.
56.5% of adults aged 25 and over hold a bachelor's degree or higher, 24% above the state share (56.5% against 45.7%). 14.5% of residents were born outside the United States, 47% above the state share (14.5% against 9.8%). The poverty rate is 11.2%, 19% above the state rate (11.2% against 9.4%).
The warmest month is Jul, averaging 75°F (24.1°C), and the coolest is Dec at 30°F (-1.1°C). About 448 mm (18 inches) of precipitation falls in a year; May is the wettest month (65 mm) and Jan the driest (20 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
Closest cities in this guide: Four Square Mile (6 miles, similar rent); Welby (7 miles, rent 10% lower); Sherrelwood (8 miles, rent 7% lower); Berkley (8 miles, similar rent). Rent differences are against Denver; use the Compare tab to put any two cities side by side.
