Land your dream remote job

Scroll is looking to hire a Senior Technical Support Engineer to join their team. This is a full-time position that is 100% remote with no geographical restrictions. Work remotely from anywhere.

We're looking for a senior rails developer to come work with us at WodBoard  WodBoard is gym management software that helps gym owners run their businesses and helps their customers, the gym members, live healthier lives.  The brand name won't make any sense unless you've walked into a functional fitness gym before so I'll move swiftly on...

We're a bootstrapped company so there's no VCs to answer to.  That doesn't mean we're not ambitious though - there's a massive market we're going after and we want to create lasting change.  As a combination of these two things we've a heavy focus on getting stuff done.

Our development ethos could be best described as "full DHH". Whilst there's some bits we don't 100% agree with we stick to the core Rails ethos and stack, focussing on what we can achieve with the technology, rather than the technology itself.  If you've enjoyed some of the blog posts on how Basecamp structure code, or enjoy the work of boringrails.com, you'd like working with us.

We're a small (but mighty) tech team of 3 so you'll be jumping straight in and writing code for customers from day 1. There's also infrastructure/UI work/mobile app development work that happens and you can become involved in if you so wish.  The role has the opportunity to build into a CTO role for the right person.

A little more about the role and us:

• It's really refreshing using technology to do something that helps people in a real world tangible way.  Changing lives and increasing health through technology is very motivating!
• We love simplicity.  We're fanatical about it.  This goes from our codebase, to our infrastructure, to how we operate as a company.  It can be harder work upfront but it sure makes life easier down the road.
• You'll need strong ownership skills.  As a small team we don't have project managers.  You're responsible for your tasks so you'll need to be good at taking ownership and reporting back to the team.
• An ability to renegotiate requirements as you get into the technical details is most welcome!  In Computer Science there's hard problems and hard problems that don't need solving.  We are constantly asking ourselves if there's an easier way to do something.
• We spend a lot of time talking to our customers and understanding their problems.  This won't ever change.  Be prepared to go back and evaluate previously held assumptions on new features after testing with beta customers

The position is fulltime and by no means do you need to be into health/fitness to work here (only about 50% of our staff are).  It's fully remote position but you'd need to be on an EU timezone so there's sufficient overlap with the rest of the team.  We also do a full team meetup in person twice per year.

The Mission

We're building the first truly intelligent insurance brokerage, transforming a $100B+ Excess & Surplus(E&S) insurance market that runs on pre-internet systems. We are looking for exceptional engineers who can architect and deploy AI systems that make complex decisions at unprecedented speed. This isn't about adding chatbots to insurance - it's about building AI systems that can handle intricate, multi-step workflows autonomously, turning weeks of manual work into automated, instant processes.

You're Our Person If

* You ship features daily and think in weekly roadmaps, not months

Hard Requirements

* Must be in San Francisco during YC W25 batch (Jan-March 2025)

Indicative Timeline Targets

Our pace is ambitious because we know what's possible. Here's what your impact could look like:

First Few Days: Master our data flows while simultaneously shipping your first feature - an AI form generation system with RAG capabilities. You'll be integrating Elasticsearch for intelligent document retrieval, proving we can move at unprecedented speed.

First Week: Transform how we handle customer interactions by deploying real-time voice AI that works alongside our human operators. This isn't just about transcription - it's about building AI that can understand complex insurance conversations and make intelligent decisions in real-time.

Second Week: Build intelligence into our market communications. Create systems that prioritize and route submissions to carriers, monitor for objections, and manage complex data flows - turning what typically takes weeks into an automated, instant process.

Third & Fourth Weeks: Take our AI systems to the next level - from handling complex voice conversations to deploying autonomous agents for payment processing and portal interactions. You'll build systems that can navigate the maze of insurance websites, extract critical information, and feed it back into our workflows.

Your Domain & Impact

You'll be building our core AI infrastructure:

* Decision Systems: Design AI that can handle complex insurance decisions

Evolving Tech Stack

Building for velocity today, engineering for scale tomorrow:

Data & Pipelines:

* Unstructured, Airbyte

AI/ML Infrastructure:

* Embedding Models: OpenAI, HuggingFace

Orchestration & Operations:

* Retool workflows, Temporal workflows

LLM Stack:

* APIs: Claude, OpenAI, Groq

Platform & Frontend:

* Cloud: GCP

How We Execute

1. Make Requirements Less Dumb: Question everything. If someone says \"that's how insurance works,\" that's exactly where we start

Our SDLC

* Boundaries of Separation: Build core IP, leverage existing tools for speed

Our Philosophy

\"Move fast. Break things. Fix them faster.\"

\"Strong opinions, loosely held\"

Join as an Owner, Not an Employee

Base compensation for this role ranges from $100-180K depending on your experience:

* Early Career (1-2 years): $100-125K

But let's be clear - if you're just comparing base salaries, you're missing the point.

We're building something that could transform a $100B+ industry, and we want our early team members to have meaningful ownership in that journey. That's why we offer significant equity packages that make you a true owner, not just an employee. We're looking for people who understand that the real upside comes from building and owning something revolutionary, not from maximizing their base salary.

Think like an owner because you will be one. If you're primarily optimizing for cash compensation, we're probably not the right fit. If you're excited about building something massive and owning a meaningful piece of it, let's talk.
