Senior Software Engineer, Backend

At Numero, we build software for political campaigns and nonprofits. Since our founding in 2019, we’ve scaled our platform to serve thousands of clients ranging from city council seats to US Senate races, and have helped them collectively manage over $10B in contributions. Our platform is an all-in-one system comprised of a donor CRM, a broadcast email/text tool, and payment processing pages that our clients rely on for their work every day. As our product is the platform that our users operate out of every day, this also means that when we build and launch new products, we do so to all of our users, at scale 🚀. We’ve experienced tremendous growth over the past 18 months and are hiring an experienced engineer to help us scale our backend infrastructure and to support the development of several new products on our roadmap. In joining our small but mighty team of 6, you will help shape our team’s culture and have a substantial impact on the success of our company 📈 — come join us! Who we’re looking for We are looking for an experienced engineer with the following skills / qualifications: A minimum of 6+ years of professional software engineering experience. Leveling and salary will be commensurate with experience. Strong understanding of SQL/relational databases and experience with data modeling. Prior experience building web applications and scaling large-scale distributed systems. Excellent written and verbal communication skills and high EQ. Excitement to build brand new products (0→1) as well as to maintain, improve, and scale our existing product lines. Some prior experience with our stack is nice to have, but a desire to work with the languages and tech we use (Ruby, GraphQL, TypeScript) is required. You are located in the continental USA (ET, CT, MT, PT) and are willing to travel 1-2x a year for company retreats and/or team offsites (usually held in California). What we’re working on Every feature of Numero is built with best-in-class engineering + design that we develop in close coordination with our clients. As a small team, we rotate working between each of our different product lines, so you’ll have exposure to wide array of projects in this role. Here are some projects that we’re currently working on: VoIP Capabilities: Building features to enable clients to make phone calls and send text messages directly within our platform using a leased or personal number. Automatically transcribe calls and add relevant notes to contacts in the CRM. Task System + Workflow Engine: Designing a modern task manager from the ground up — with rules-based workflow engines to help clients’ automate their work within our CRM. AI Automations: Developing AI automations to help our clients work faster and easier across a range of their work — including content generation, task / workflow automation, and general data hygiene (e.g. merging duplicates, appending missing data, etc). Tandem Fundraising: Creating a system that lets clients split contributions from payment processing pages between multiple recipients, with careful and precise handling for fees, compliance reporting, refunds, and other edge cases. Integrations + Webhooks: Enabling a two-way sync of our data with various tools that our clients use — both through direct integrations and realtime webhooks. This is more important as we are becoming the system of record for our clients' fundraising data. Custom Fields: Architecting a system allowing clients to create custom fields to store and query different types of data in their CRM. Add support for configuring data types and enforcing format validations. Enable performant querying of this data via NumeroQL. Scaling NumeroQL: Optimizing our custom-built query language (NQL) that receives millions of daily requests from our various frontends. Improve query performance and enhance it’s ability to filter billions of records across multiple databases in realtime. What we value Here are some of the concepts that we value as a team and hope resonate for you: Consistent + Clear. You have seen how prioritizing consistency and clarity in a large code base increases productivity, shared understanding, and velocity on small teams. Eager, excited learners. You are able to jump into different parts of the stack to develop (or debug), and are happy to pair with others to trade learnings + brainstorm solutions. Shipping-first orientation. You have a bias toward action and are interested in building the right solution that solves a customer’s needs without sacrificing quality or resiliency. Clear, thoughtful communication. You value collaboration and are happy to share your thoughts and ideas directly with team mates in both writing and on calls. Follow Through, Hygiene. You both enjoy completing your work, but also cleaning up tech debt along the way and leaving the codebase in a better state over time. Tech Stack Our platform is built with a Ruby/Rails backend that serves data to several TypeScript/React frontends using a GraphQL API. We use Postgres as our primary database, but also store and serve some data from MongoDB and OpenSearch for specific use cases. The following is a list of some of the technologies you can expect to work with: Backend: Ruby, Rails, Ruby GraphQL, Sidekiq, RSpec Frontend: TypeScript, React, NextJS, Apollo GraphQL, Tailwind, Jest Database: Postgres, MongoDB, OpenSearch, Redis Monitoring: Sentry, PgAnalyze Hosting / CI: Heroku, AWS, Vercel, Github Actions, Ubicloud Depending on your experience, you may work more on one side of the stack than the other, but as a small team that values learning and growth, there will be projects that may require you to work on parts of the stack that you’re less familiar with (we hope this excites you)!

We also offer the following benefits to help you to do the best work of your career: Flexible PTO (including 12 company holidays and 2 weeks of required PTO each year) Medical, dental and vision coverage with HSA option; 50% coverage for dependents Paid Parental Leave for primary and secondary caregivers Your choice of premium tech setup – laptop, monitor, accessories, and headphones $1,000 for your work-from-home setup Stipend for co-working 1 day / week (e.g. WeWork) Annual company retreat and/or team offsites
