Narrative has been building a data collaboration platform designed for simplicity and ease of use since being founded in 2016.
Our primary strength is functioning as a data marketplace where we differentiate ourselves by automatically standardizing data, making platform data accessible through the Narrative Query Language (NQL), giving data providers the ability to define row-level access and pricing policies, and making it easy to deliver data to a variety of destinations using our "Connector Framework".
We operate two flavours of our platform: An AWS-based implementation that runs on our infrastructure, and a Snowflake-based version running inside the user's Snowflake account.
We are a small, remote-first team looking for great developers who want to jump in and take major systems and user-facing features from design to launch. While the company's headquarters are in NYC, the development team currently includes engineers working from the US (California and New York), Canada (Alberta, British Columbia, and Québec), Poland, and Serbia.
In brief, the technologies we use are:
- Backend: Scala, Spark, Apache Iceberg, Apache Calcite, Cats, Cats-Effect, Http4s, FS2, Doobie, Deequ, Axolotl, BentoML, and HuggingFace Transformers.
- Frontend: Typescript, VueJS, Nuxt, Vite, and Cloudflare Pages.
- Operations: AWS (ECR, ECS, EMR, RDS, S3, etc.), Datadog, Docker, Terraform, with some burgeoning use of EKS/Kubernetes.
Job postings and more on information about our team and culture are available at: https://jobs.narrative.io/

Bubblehouse is a fast-growing custom and private loyalty platform. Headquartered in NYC, the entire team is fully remote and spread across US and Europe. We power loyalty programs for large brands, including household names.
We’re again expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.
Tech-wise, we’re running on Golang, and using custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database.

3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.

Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.

We have sophisticated logistics optimization software, a polished consumer product, and firm business fundamentals. We're now over a decade old - this is a stable, yet consistently growing and innovating, company.
Given our distributed nature, we have growing network and workstation infrastructure, and it's time to hire our first full-time leader to manage this system. The ideal candidate can:
- Operate with autonomy and integrity across network, server, infrastructure, and desktop environments
- Communicate cross-functionally, to internal stakeholders at all levels
- Navigate our (primarily Linux) technical environment
- Spearhead projects to improve our technology's security, reliability, and functionality
- Facilitate our corporate efficiency via desktop administration
Because this role has some physical hardware responsibilities, we'd prefer it be filled by someone in the above localities, even though the vast majority of the role can be performed remotely.
We're open to both newly-graduated or more senior technically-minded individuals and managers, provided they meet our bar.

Nebula is building a modular blockchain stack to make on-chain finance faster, fairer, and more efficient than off-chain. The stack has 3 parts:
1. Execution environment – combines Rust + Sovereign SDK for highly performant, expressive private apps (e.g. solving latency asymmetry in exchanges). 2. Privacy protocol – blends cryptography + privacy hardware for verifiable, fast programmable privacy. 3. Nebula Exchange – a hyper-performant exchange using batch auctions + private orders to eliminate latency asymmetry and guarantee best prices. We’re hiring ambitious engineers to join the core team:
- Frontend (React/TS/Next.js) – focus on architecture, design systems, interactivity, realtime apps, Figma → production.
- Backend (Rust/Go) – core infra + SDK integration.
Requirements: detail-obsessed, independent problem solver, thrives in chaos, good communicator, can work ET hours. Nice to have: exp. in financial exchanges, realtime data-heavy apps, web3. Note: workload can be intense (sometimes 80+ hrs/wk).

Channel3 is hiring a Founding Engineer to help us build a database of every product on the internet.
Our API lets any AI app or agent add shopping capabilities and earn commission on sales. As commerce moves from in-store, to online, to AI-native, this universal product catalog becomes critical infrastructure. We see Channel3 becoming as foundational to AI commerce as Stripe is to payments or Plaid is to fintech.
We just closed a $6M seed round led by Matrix (Apple, FedEx, AfterPay) with participation from Ludlow (Honey, StockX), Y Combinator, and Paul Graham. We're live with 500+ developers on our API and millions of products processed daily.
We're looking for engineers who want direct ownership of technical decisions, love solving hard problems at scale, and want to help build our team and culture from the ground up.
This role is in person, 5 days a week, in NYC. Unfortunately, we cannot sponsor visas.
