About the Role
At Klaviyo, the ARIA (Applications, Resources, Intelligence, and Automations) team is building AI systems that transform how our employees work. As an AI Builder Resident, you’ll join a cohort of builders focused on developing AI-powered internal tools that automate workflows, improve knowledge access, and unlock productivity across the company.
This is a 1-year, hands-on builder program (starting June 22, 2026) designed for candidates who have demonstrated the ability to build real things with AI. You’ll embed directly with business teams, working on high-impact problems and shipping production-ready agentic AI solutions. This role focuses on building and deploying agentic and LLM-powered applications in production, with an emphasis on learning, execution, and growing your ability to work across the AI system stack.
This role sits at the intersection of engineering, product thinking, and real-world problem solving. It emphasizes execution, curiosity, and ownership, with the expectation that you’ll actively build, iterate, and deploy—not just observe. This role is designed to accelerate your growth by giving you direct ownership of real problems and production systems from day one.
How You’ll Make an Impact
- Embed with business teams to identify opportunities: Partner with internal teams to uncover workflow inefficiencies and translate ambiguous business problems into AI-powered solutions. Own problems end-to-end from discovery through deployment, not just execution.
- Build AI-powered workflow automations: Design and implement solutions that automate repetitive or complex tasks using LLMs and agentic workflows.
- Develop agent-based systems and integrations: Build AI agents that can take actions, chain tasks, and integrate with internal systems (e.g., HR, CRM, ticketing tools). Surface insights and patterns from deployments to inform broader AI platform and tooling improvements
- Ship internal AI tools into production: Use AI-assisted coding tools to rapidly prototype, gather feedback, iterate, and deploy scalable, production-ready systems used by teams across Klaviyo. Ensure solutions are adopted and deliver real impact.
- Advance team AI maturity: Help teams move from basic AI usage to more advanced capabilities (e.g., structured workflows, agent orchestration, deeper integrations)
- Collaborate to scale solutions: Work directly with stakeholders day-to-day and alongside teams such as Amplify and GTS to deploy and operationalize AI solutions at scale.
- Contribute to a culture of building: Act as a visible example of Klaviyo’s “built different” mindset—taking initiative, experimenting rapidly and delivering tangible results.
We are open to a variety of backgrounds. The most important signal is your ability to build and ship with AI.
Core Qualifications
- Able to work on-site in Boston for the full 1-year program (40 hrs/week) starting on June 22
- Demonstrated experience building something real with AI (e.g., side project, automation, product, tool, or workflow)
- Comfort using AI-assisted coding tools to develop and iterate quickly
- Working knowledge of Python and/or modern scripting/backend tools
- Familiarity with best in class LLMs, APIs, and basic system integration concepts
- Ability to learn quickly and operate in a fast-paced, ambiguous environment, taking initiative to define and solve problems without waiting for direction
Candidate Profile
- Curious, resourceful, and action-oriented with a strong bias toward building
- Comfortable figuring things out independently and pushing projects forward
- Strong alignment with Klaviyo’s builder culture: curious generalists motivated by impact and continuous learning
- Does not require visa sponsorship now or in the future
Nice to Have
- Experience building agentic AI workflows
- Exposure to RAG systems, embeddings, or vector databases
- Experience integrating APIs or working with internal tools/systems
- Familiarity with cloud platforms (AWS, GCP, Azure)
- Background can vary across software engineering, IT, or career-switch paths (Computer Science degree not required)
- Exposure to frontend or full-stack development
This program is designed to unlock a new type of AI builder at Klaviyo—people who can quickly identify problems, build solutions, and drive impact with AI. You’ll help shape how internal teams adopt and scale AI, while gaining hands-on experience with agentic systems, LLM applications, and real-world deployment.

What the Team is Saying
Klaviyo Compensation & Benefits Highlights
How does Klaviyo ensure its pay and bonus plans are competitive?
Klaviyo supports competitive pay through a total rewards approach that combines salary, equity, bonus opportunities, benefits, learning support and a performance culture tied to measurable impact.
- Competitive total rewards: Klaviyo’s benefits overview highlights competitive salaries, 401(k) match, employee referral bonuses, equity, an employee stock purchase plan, flexible paid time off, commuter/transit support, fitness reimbursements, mental and emotional wellbeing programming and learning support. External reviews reinforce the value of the package, with employees citing competitive pay, bonuses, RSUs, ESPP, health insurance, parental leave, unlimited PTO and learning stipends as meaningful parts of the employee experience.
- Pay connected to impact and outcomes: Klaviyo’s handbook frames performance around ownership, clarity and measurable results. The value “Know the score” states that results matter more than effort alone, while “Drivers wanted” emphasizes proactive ownership and “Be meticulous in your craft” reinforces a high bar for work quality. That creates a compensation and recognition philosophy where strong outcomes, not just activity, are central to advancement and rewards.
- Equity and long-term value: Equity is a visible part of Klaviyo’s rewards story. Klaviyo offers equity packages to all full-time employees, vesting over four years, and provides an employee stock purchase plan. That ownership opportunity sits within a growing business: in Q1 2026, Klaviyo reported $358 million in revenue, up 28% year over year, and raised full-year 2026 revenue guidance to $1.514 billion to $1.522 billion. Those business results give employees a clear connection between company performance, long-term growth and the value of ownership-based compensation.
- Rewards supported by growth and development benefits: Klaviyo’s compensation package is paired with benefits that help employees grow their careers and build long-term value. K-Pro Learn, learning stipends, mentorship, Career Architecture and manager development programs support continued skill-building. A customer success manager noted that Klaviyo offers a learning stipend for job-related coaching or training, while employee survey insights show 78% of respondents feel they are gaining the skills and experience to grow their careers.
- External signals:
- Compensation Sentiment: External reviews frequently praise Klaviyo’s competitive salary, bonuses, equity, RSUs, ESPP, 401(k) match, learning stipend and generous benefits. (Glassdoor; Comparably)
- Rewards Ratings: Comparably rates Klaviyo’s compensation an A and perks and benefits an A. (Comparably)
- Employee Value Signals: Reviews highlight PTO, health insurance, parental leave, office amenities, learning support and work-life balance as part of the overall rewards package. (Glassdoor; Comparably)
Bottom line: Klaviyo keeps compensation competitive by combining salary, bonus opportunities, equity, ESPP, retirement support, benefits and learning resources with a culture that rewards ownership, measurable outcomes and long-term impact.
