Job Title: Software Engineer II - Marketing Agent
Location: Boston, MA (Hybrid 3x week)
At Klaviyo, we believe the future of software lies not in productivity tools for human users but in systems that do the hard work for them. We’ve built the infrastructure and applications that power the interface between businesses and consumers — supporting over 183,000+ customers, billions of consumer profiles, and hundreds of billions of customer interactions. Now, we’re building the next generation of AI agents that can automatically create, execute, and optimize marketing and customer experience strategies for any business.
As a Software Engineer II on Klaviyo's Marketing Agent team, you'll be at the forefront of one of the most impactful bets we're making — building an AI-powered system that autonomously creates and executes high-stakes marketing strategies on behalf of thousands of customers. This isn't backend plumbing: the work you ship directly drives revenue for the businesses that rely on Klaviyo every day. Partnering closely with product managers and technical product owners, you'll shape the scope of what's possible, turn ambitious ideas into production reality, and craft tools so intuitive they feel like superpowers to the marketers using them.
This role is primarily backend, with a strong focus on crafting robust and maintainable AI powered systems that deliver high quality strategies and marketing content that’s ready to use to our customers. There are ample opportunities for growth given the scope of this role and the team’s central role in Klaviyo’s product.

Groma's mission is to allow everyone to own their bit of the world. We accomplish this via GromaCoin, an on-chain asset that represents diversified ownership in the Groma Real Estate Trust, a growing portfolio of real estate that currently includes 130+ buildings. Groma focuses on purchasing in the massive but historically overlooked small unit count multifamily sector, which includes millions of 2-40 unit buildings across the U.S. Our property technology platform uses AI and IoT to bring new efficiencies to these buildings and ultimately enables us to acquire, upgrade, and operate them efficiently at scale. Our investor technology platform makes owning these assets accessible to a broad array of investors, with bespoke vehicles available to institutional and family office investors and our flagship vehicle available to everyone, with a special focus on enabling ownership for the residents in our buildings. Visit www.groma.com to learn more about us.
This senior-level role will join a small team of software engineers that build the digital infrastructure and products that power the company. These primarily include:
The most important traits for someone joining the team will be:
The core technologies that the team uses are:
This is a role for someone that can quickly ramp up to execute independently and effectively across the range of technologies described above. You do not need to be an expert in everything mentioned, but should be very comfortable building web applications in Django or a comparable framework and at least interested in learning the rest.
At Groma, we’re looking to build something big and are on a fast growth trajectory. A healthy work-life balance is important to our team, but we also expect a high degree of commitment from every team member. We strive to respect individuals and their needs, while also acknowledging the reality that we have a small team that is trying to accomplish some very ambitious goals in a short period of time.
We are also focused on maintaining our dynamic in-office culture at Groma’s headquarters in beautiful downtown Boston, Massachusetts. We believe that in-person collaboration and spontaneous interpersonal interaction is critical to the company’s success at this stage. Also, our office is great - we own the whole building and have made it very much our own space. We’ve got a gym, locker rooms, a game room, a rooftop garden, and all the normal stuff to make an office an effective and fun place to be. We understand that everyone will occasionally need flexibility, but want to be explicit that this is a fully in-person role.
We have an ever-evolving list of values and conventions that guide how we operate as a company, but here are some of our core ones:
While we think that this role is an amazing opportunity for the right candidate, we also want to be upfront about some of the reasons that it might not be a fit for you:

Job Title: Sr. Lead AI Engineer
Location: Boston, MA
This role is based in our Boston, MA hub (Hybrid-3x week).
At Klaviyo, we believe the future of software isn’t just better productivity tools for humans—it’s systems that can run, optimize, and adapt themselves based on outcome and reward signals. We’ve already built the infrastructure and applications that sit between businesses and consumers—serving 183,000+ customers, billions of consumer profiles, and hundreds of billions of messages and conversion events. Now we’re investing heavily in Marketing AI and Service AI: the shared services and agentic capabilities that power AI‑native experiences across Klaviyo.
As a Sr. Lead AI Engineer in the AI & Analytics organization, you’ll be the technical leader for a set of high‑impact AI services and agentic systems. You’ll own architecture and execution for complex, distributed backend systems; guide other engineers through design and implementation; and partner closely with product, machine learning, and data science to turn AI ideas into reliable, scalable production capabilities. This is a hands-on tech lead role, not a people‑manager role.

Please note that this role is full-time in-office and based in Boston, MA.
Groma is blending real estate and technology to unlock a new real estate asset class while making it easier for everyone, from institutional investors to the residents in our buildings, to participate in ownership. Our property technology platform uses AI to bring new efficiencies to the small unit count multifamily sector, enabling us to efficiently acquire, upgrade, and operate these 2-20 unit multifamily buildings and bring institutional performance to this massive but historically overlooked sector. Our investor technology platform makes owning these assets accessible to a broad array of investors, with bespoke vehicles available to institutional and family office investors and our flagship vehicle, the blockchain-powered GromaREIT, available to everyone, with a special focus on enabling ownership for the residents in our buildings. Visit www.groma.com to learn more about us.
This senior-level role will join a small team of software engineers that build the digital infrastructure and products that power the company. We're looking for someone that has hands-on experience building, deploying, and maintaining smart contracts in a production environment on EVM networks (Ethereum and Base), as well as experience working with a variety of token standards. Specific nice-to-haves include experience with RWAs/real estate, representing securities with compliance constraints on-chain (e.g. ERC-3643), and DeFi protocols like Uniswap.
While we're looking for an engineer with this background, please note that we also expect all engineers to be willing and able to contribute across our entire technology stack. The primary products that you'll be working on include:
The most important traits for someone joining the team will be:
The core technologies that the team uses are:
This is a role for someone that can quickly ramp up to execute independently and effectively across the range of technologies described above. You do not need to be an expert in everything mentioned, but should be very comfortable building web applications in Django or a comparable framework and at least interested in learning the rest.
At Groma, we’re looking to build something big and are on a fast growth trajectory. A healthy work-life balance is important to our team, but we also expect a high degree of commitment from every team member. We strive to respect individuals and their needs, while also acknowledging the reality that we have a small team that is trying to accomplish some very ambitious goals in a short period of time.
We are also focused on maintaining our dynamic in-office culture at Groma’s headquarters in beautiful downtown Boston, Massachusetts. We believe that in-person collaboration and spontaneous interpersonal interaction is critical to the company’s success at this stage. Also, our office is great. We own the whole building and have made it very much our own space. We’ve got a gym, locker rooms, a game room, a rooftop garden, and all the normal stuff to make an office an effective and fun place to be. We understand that everyone will occasionally need flexibility, but want to be explicit that this is a fully in-person role.
We have an ever-evolving list of values and conventions that guide how we operate as a company, but here are some of our core ones:
While we think that this role is an amazing opportunity for the right candidate, we also want to be upfront about some of the reasons that it might not be a fit for you:
