Senior Software Engineer, Frontend

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 modern frontend architecture, frameworks, and best practices.
• Mastery of JavaScript (TypeScript preferred!), CSS3, and HTML5 and DOM / web APIs.
• 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.
• Prior experience with our stack is nice to have, but a desire to work with the languages and tech we use (TypeScript, React, GraphQL) 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:

• Conversion Optimization: Improving and optimizing donation conversion rates on our ultra-fast, accessible contribution and petition pages through advanced frontend caching, server-side rendering, and data-driven optimization strategies.
• VoIP Client: Building a web and mobile UI that supports making realtime phone calls (e.g. WebRTC) and text messages with contacts to support our clients’ daily donor outreach.
• Messages Inbox: Developing a system to enable our clients to respond to inbound text and email messages so that they can operate a shared inbox as a team directly on our platform.
• Robust Report Visualizations: Building high quality, modern data viz components including charts, tables, and funnel views either fully custom from scratch or using advanced libraries (Chart.js, Nivo, Visx, etc).
• Task System + Workflow UX: Building a task manager UI — with rules-based workflow visualizations to help clients’ automate their work within our CRM.
• Scaling Numero Component Library: Abstracting and generalizing common component patterns across several different frontend client contexts for streamlined styling, behavior, and visual testing.

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)!

Compensation + Benefits

For this role, we offer a salary in the range of $150,000 - $190,000 and equity. 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

We aim to keep our interview process lightweight + efficient — we can move from an intro phone call to an offer within a week. It generally involves the following steps:

• Intro Call: A ~45 minute call with our CTO to review your background + experience and learn more about the role. If there is a mutual fit, we’ll schedule a technical interview.
• Technical Interview(s): A half day of interviews with engineers on the team. Includes a database modeling exercise, a live coding exercise, and a paired code review.
• Final Interview with Cofounders: A quick ~30 minute chat with our other two cofounders to give you and and our founders a chance to ask questions.

If all goes well, the next step is extending an offer 🎉!
