Waterlily uses advanced AI to tackle one of the biggest, unsolved challenges in retirement planning: long-term care (LTC). We have already closed enterprise deals with multiple Fortune 100 insurance carriers and distributors, and raised an oversubscribed $7m Seed round from backers such as Insight Partners, Nationwide, Edward Jones, Brewer Lane Ventures, and Genworth. Our mission is to help families proactively plan for LTC needs and costs, and reduce America's multi-trillion-dollar LTC crisis.

We have extremely high standards and expect our team to move quickly while maintaining top quality. Our interview process is rigorous, and most applicants will not pass. Those who do join a small, highly skilled team working directly with our founders (who started college at ages 11 and 14, attended UC Berkeley and MIT, and have built and sold successful startups backed by Founders Fund and Khosla Ventures before). We value rapid learning, candid feedback, and intense execution. We all invest more than 50 hours a week, sometimes up to 80, when needed to achieve top-tier outcomes. We want people who thrive in that environment, with the maturity to also pace themselves for sustainability.

We believe SMBs are the backbone of American society and small business ownership is the best path to wealth creation and economic mobility for many Americans. We're trying to dramatically lower the activation energy in just one of the major hurdles for aspiring small business owners: accounting and bookkeeping.

Our approach is working! We embed directly within an SMB's primary business platform, manage all the data syncing & reconciliation for them, and have real humans (with real AI tooling) handling their books. We do this at ~half the cost of existing bookkeeping services and it's still profitable for us because we're saving so much time with our data access + AI.

Adoption is taking off faster even faster than we hoped and we need to grow the team! We're a team of 5 who like working with a high ownership and high throughput collaboration. We have serious technical challenges across scaling systems, data modeling, and building AI-driven automations of tedious tasks.

Our hiring philosophy is simple.

1. The early engineering team isn't just building products, it's setting the culture, practices, and standards for the whole org. Find teammates who have the appetite and agency to go beyond excellent code.

2. No one knows more than 10% of what they need to be successful at an early stage startup. Find teammates with the highest trajectory of learning and growth and give them as much opportunity and responsibility as they want.

3. We talk to real small businesses with real problems every single day. Find teammates who want to win by making our customers successful day in and day out.

Are you a web developer who’s always wanted to make indie video games? This is for you. Elsewhere is a San Francisco-based game studio building multiplayer roguelike games. We’re working on two projects, one of which is a roguelike deck builder in the vein of great titles like Inscryption and Slay the Spire with a little Pokemon TCP and Marvel SNAP thrown in. We’re building games with TypeScript, React, and HTML/CSS as well as Websockets (via Colyseus). We’re using generative AI in a fascinatingly new and creative way that naturally extends game mechanics into something tens of millions of people will absolutely love.

Ideally, you:

* Have worked as a software engineer before, ideally on a small team.

* Have built and shipped games before, either professionally or on your own time.

* Love games yourself, and have always wanted to work in the games industry.

* Know the web stack (TypeScript, React, etc) like the back of your hand

We’re stealth but backed by some of the top investors in Silicon Valley, including Floodgate and a16z SPEEDRUN. My previous startup was Human Interest (YC S15), a fintech co that today is valued at $1.3B. My intention is to outdo it many times over with Elsewhere. We’re building the the Blizzard, Valve, or Nintendo for the AI age. I hope you’ll consider joining us.

Elicit is an AI research assistant that uses language models to help researchers figure out what’s true and make better decisions. We scaled to >$5MM annual revenue and 450k MAU fast. We're hiring for multiple roles and are primarily interested in people with early-stage company experience, who are comfortable in high-agency, fast-paced teams.

Reasons you might want to join Elicit:

1. We have been thinking about how to apply AI for high-stakes knowledge work since even before GPT-1. Elicit was spun-out from Ought (https://ought.org/) which was an applied research lab.

2. If you're concerned about the potential downsides and risks of super-powerful AI: so are we! Happy to explain more of this story on a call, or you can also check e.g. https://ought.org/updates/2022-04-06-process for a primer.

3. We like spending time with each other, and have get-togethers every 6 weeks, but we're flexible on location.

Reasons you might not want to join Elicit:

1. We've found a level of product market fit (as evidenced by metrics) but we've not proven everything out yet. If you want predictability, Elicit is not for you.

2. We aim to hire people who thrive in low-bureaucracy environments, and let them loose. If you need structure, lots of support, close mentorship, or tightly-defined work assignments, Elicit is not for you.
