BuildBetter | Senior Engineer (Backend, Full-stack) | Full-Time | Remote (US) | 170-200k base + equity | Visa Sponsorship not provided

BuildBetter is the product operations platform for customer-led teams. We've built an AI-first product that lets our customers, like Rappi, n8n, and Posthog, automate the operations work that lets them provide their customers with world-class product experiences.

We're looking for two senior engineers to join the team; our headcount has remained small while growing revenue, and we're now bottlenecked by development speed in a way that will make you invaluable. You'll have real ownership over your code from product ideation to customer support, and we'll be making substantive product updates weekly. We're looking for team players who are as fun to work with as they are productive, and are willing to compensate these two rolls commensurately - our aim is to be in the 95th percentile of equity compensation, and we expect that in exchange we'll have value-aligned employees who will help us grow the business.

Joining us will mean solving hard problems at the frontier of AI adoption, including:

- maintaining performance at scale

- building and maintaining rich frontend user experiences that maintain the standards of usability and delight that our customers know us for.

- building agent and workflow systems that automate real work for customers

- playing around with the latest models to figure out new experiences that we can offer our customers as cutting-edge models get released monthly

- building automation that's grounded in supporting product teams rather than automating them - our bet is that this is the likelier outcome out of the current generation of AI systems

Stack: Postgres / TS (Nest + React) / Hasura / EKS / S3 / LLM APIs / Python

Benefits:

- unlimited PTO

- $100/mo education stipend

- flexible hours: we measure productivity in terms of outcomes, not time, so as long as you're able to stay aligned, productive, and in regular communication, we don't really care what hours you work

- health insurance

ALSO LOOKING FOR: Senior Product Designer | $105k - $180k USD | Design + code in HTML & CSS (Tailwind)

This may not be the “right” place to ask this, but I am a software engineer in the entertainment industry and it’s pretty bad right now. What is a pivot I can make? My skills are mostly C++ and Python.

Sounds familiar. This is the company that wants to pay ~$2k a month and is looking for engineers in the third-world. They will also deny you if you are in the US and looking to put something recent on your resume and don't care about salary.

Surge AI (https://surgehq.ai/careers) | Software Engineers (full-stack / product) and Strategic Project Lead, and many more https://surgehq.ai/careers | Full-time | ONSITE SF or NYC | Remote

Our mission at Surge is to build the human infrastructure behind the next wave of AI and LLMs. We operate the largest human data platform in the industry and power the AI teams at all of the top AI labs.

- Creating the GSM8K dataset: https://www.surgehq.ai/blog/how-we-built-it-openais-gsm8k-da...

- Collecting RLHF data for Anthropic's Claude: https://www.surgehq.ai/case-studies/anthropic-claude-surgeai...

You’d be joining a rapidly growing team of former engineering and ML leaders from Google, Meta, Twitter, and Airbnb. We work in small groups, ship quickly, and value autonomy and ownership. No previous AI experience is required, if you have the engineering skills you can learn what you need on the job.

We're looking for senior engineers to work out of our offices in SF or NYC, or remotely. Please reach out to us at Email is hidden with a resume and 2-3 sentences describing your interest. Excited to hear from you!

Speckle | Backend (Engineering), Founding Account Executive (Growth) | Full-Time | REMOTE | US East, London, EU | https://jobs.ashbyhq.com/speckle

At Speckle [0], we’re on a mission to shake up the AEC (Architecture, Engineering, and Construction) industry. To do that, we're building the OSS data layer for AEC to operationalize how the built environment industry works with data and automation. Think of us as a cross between Github and Palantir, with an opportunity to significantly impact a $10 trillion industry. Our platform already powers workflows on billion dollar projects at leading firms like Suffolk, Multiconsult, Pomerleau, and Stantec.

I'm the CEO/founder and I can honestly vouch that we're tight knit team that values autonomy and shipping cool product on top of our data layer (me included - and this might be a red flag for some, but it's my therapy) over hierarchy, politics, levels and complexity (my spirit animal is the grug brained developer). We love working together with our customers - construction is truly a unique place where each project is its own micro universe.

We have multiple roles open across engineering and growth (sales & marketing) [1]
