About Everyday Agents

Consumer Travel is Ripe for Disruption

Today's travelers are seeking personalized, immersive, and authentic experiences that reflect their unique tastes and interests. They want to be inspired, to feel the thrill of discovery, and to seamlessly benefit from technology throughout their journeys. Yet, the current travel landscape is a maze of disjointed self-serve transactions, often leaving travelers feeling frustrated and unfulfilled. The explosion of travel booking sites is sucking the fun out of getting away, with travelers needing to visit dozens of websites to plan a trip and often needing to resort to time consuming offline strategies. As a result, the joy of travel is often overshadowed by the stress of planning, with travelers spending significantly more time researching a vacation today than just a few years ago.

Our AI-Native Travel Concierge

Introducing Everyday Agents, a stealth startup backed by four top venture funds that is reimagining the way we travel. Everyday Agents is building an AI-powered Travel Concierge (currently in private beta) that simplifies the process of discovering, planning, and booking trips, all in one app. It intuitively understands your preferences, assists in uncovering stays, activities, and dining options, and supports travelers throughout their journey, from exploring potential destinations to accommodating last-minute changes during a trip. It’s like having a personal travel agent, but better, as it’s affordable, available 24/7, responds within seconds, and is armed with local insights, captivating photos, maps, itineraries, pricing, and availability. By harnessing the latest advancements in Large Language Models (LLMs) and pioneering breakthroughs in Agent Architectures, Everyday Agents is poised to revolutionize the travel industry.

Market Opportunity

Contributing over 10% to the global GDP, the travel and tourism sector is on the brink of a significant transformation resulting from fundamental shifts in consumer preferences. Newer generations are prioritizing experiences, particularly travel, over material possessions, and the influence of social media is further fueling this trend by inspiring travelers to seek out unique and personalized experiences. As a result, the online travel market, already a $2.3 trillion industry, is projected to grow by more than 10% per year through 2030. With its focus on crafting exquisite, personalized trips, Everyday Agents is well positioned to capitalize on these trends and transform the way we travel.

Why Everyday Agents?

Everyday Agents' ability to execute this vision is underpinned by an experienced founding team and investors with highly-relevant expertise. Our CEO is Jonathan Downey, a three-time AI-startup founder, MIT engineer, and 3rd generation pilot with a lifelong passion for travel. Additional co-founders and founding team members bring decades of expertise in consumer apps and data-driven personalization and include a senior data leader from Stitchfix and the Head of ML from Candidate Labs. The company is backed by former executives from Pinterest, Twitter, and Stitchfix alongside top AI-focused venture funds including SignalFire, Moxxie Ventures, and Fuel Capital.

The Role: Founding Backend Software Engineer

We are currently searching for our first backend engineer who can own the business logic and database layers of our runtime, as well as flex up to the React side when needed. You will be joining a team that is pushing the boundaries of leveraging LLMs, requiring you to create novel ways for our LLM team to interface with APIs you create.

As a founding engineer and early employee you will help take us to a public launch where an amazing user experience brings joy and sparks user growth. You will be on a small team of high caliber software engineers, ML engineers, and data scientists solving big problems collaboratively while planning, building features and shipping code. This role is the bridge connecting people and infrastructure together through a Python based codebase serving as the common denominator. As an early hire your technical decisions will be paramount as you will need to balance moving quickly with the reality your architecture will need to be extended by future team members.

About You

  • You are excited to be part of the LLM transformative wave to help forge tooling, observability, and eventually discovering best practices around LLM development

  • You highly value constantly tinkering with code making it more readable, maintainable and performant, but you are also able to make tradeoffs to create momentum and capture opportunity

  • You craft thoughtful SDKs and APIs that serve as building blocks other developers intuitively understand

  • You know how and when to scale your code, understanding the tradeoffs of concurrent, parallel, and distributed runtimes

  • You love to ship code to production daily in a safe and responsible way by leveraging a combination of unit and integration tests

  • You love to solve hard problems by coding an elegant simple solution

  • You enjoy working with product to propose alternative solutions by clearly articulating tradeoffs

  • You come to the table with strong opinions, yet are loosely held.


  • Extensive experience building and running application servers supporting high throughput

  • Can architect an API supporting multiple clients including web, mobile and LLMs, each potentially working on different version contracts

  • Ability to create software abstractions to handle cross cutting concerns such as logging, observability, and robustness

  • Can stand up cloud infrastructure, particularly comfortable building and deploying containers

  • Solid experience with ORMs, SQL and measuring / optimizing performance issues in queries

Bonus Criteria

  • Proven track record shipping software in highly dynamic early stage startup environment

  • Familiarity with Python and its ecosystem, particularly comfortable with concurrent / future based programming via FastAPI

  • You have built stream and batch based ETL pipelines

  • Experience with multi variant testing and rolling out new code behind feature flags

  • You have operations and configuration management experience to create fully managed immutable infrastructure

  • Have strong skills in proposing new schema changes through ER diagrams

  • Stood up CI/CD pipelines enabling dev teams to move fast with confidence

  • You have some hands on experience tinkering with LLM tool chains such as GPT, Langchain, HuggingFace, etc
