Senior Software Engineer, Agentic AI

Austin, TX

Full Time

Experienced

Who You Are:

You’re a seasoned software engineer ready for your next challenge. In this role, you’ll join Invicti’s newly formed AI team as a Senior Software Engineer, Agentic AI, and play a pivotal role in building our next-generation Agentic AppSec solution. As AI reshapes how software is built and how attackers exploit it, you’ll help give defenders an edge by applying attacker-inspired techniques to solve modern security challenges.

You design, build, and deliver software solutions rapidly, working across the stack from agent architectures and memory systems to integrations with security tools and developer workflows. You collaborate closely with product and security teams to deliver capabilities that solve real customer problems. You thrive in a high-ownership role on a small team, where your technical decisions directly shape the product, with an initial focus on agentic pentesting.

What You’ll Be Doing:

Multi-Agent System Development: Design and implement autonomous agent systems in Python using frameworks like AWS Strands Agents, with emphasis on orchestration, reasoning, and decision-making
MCP Integrations: Create Model Context Protocol integrations connecting Octo to security tools, developer environments, and AI coding assistants like Cursor and GitHub Copilot
LLM Prompt Engineering: Develop and refine prompt chains for real security use cases, including triage, prioritization, and remediation
RAG & Memory Systems: Build retrieval-augmented generation pipelines and memory architectures that give agents a persistent, contextual understanding of customer environments
End-to-End Ownership: Own features from design through production — build, test, deploy, and measure outcomes
Cross-Team Collaboration: Work closely with product, platform engineering, security research, and infrastructure teams to ensure we're building what customers need
Experimentation & Productization: Evaluate new AI/ML capabilities and determine how to bring them to production

What You’ll Need:

5+ years of production software development experience with a track record of shipping high-quality solutions
Hands-on experience building LLM-powered applications, RAG systems, or agentic AI
Strong Python proficiency with solid software engineering fundamentals
Understanding of distributed systems, API design, and cloud-native architectures
Experience with prompt engineering, embeddings, and vector databases
End-to-end software development skills, including frontend development, building pipelines, tests, monitoring, and scalability
Ability to balance engineering rigor with pragmatic delivery, embracing agentic coding tools like Claude Code to accelerate delivery
Clear communication skills — you surface problems early and propose solutions

What’s Preferred:

Experience with agent frameworks (AWS Strands, LangGraph, AutoGen, CrewAI) in production environments
Familiarity with MCP (Model Context Protocol) and AI tool integration patterns
Background in application security, penetration testing, or security tooling
Experience with Go or C# for performance-critical components
Ability to build single-page applications using Vue.js
AWS experience with Bedrock and Kubernetes deployments
Familiarity with using GitLab for source control and CICD
Knowledge of evaluation methodologies for LLM systems (benchmarks, red-teaming, human feedback)
Experience building third-party product integrations using REST APIs
Contributions to open-source AI/ML projects

What You’ve Got:

Strong problem-solving mindset with intellectual curiosity about AI/ML
High degree of ownership, accountability, and initiative
Comfortable working in fast-paced environments where prototypes are rapidly iterated or discarded
Excited about autonomous AI systems and seeing your work used by real customers
Adaptable and effective working across distributed teams
Detail-oriented, with a focus on delivering systems that scale and last

Voluntary Self-Identification of Disability

Voluntary Self-Identification of Disability Form CC-305
OMB Control Number 1250-0005

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
