Signal Send

Careers

Build with us

Signal Send is early, customer-funded, and built by people who like owning outcomes — not waiting for a ticket to move through three teams.

We help marketing teams turn messy CSV exports into segmented, personalized campaigns they can actually send — with clear data controls, AI-assisted planning, and export into the tools they already use. The product is real, the customers are real, and the problems are concrete: bad columns, nervous legal reviews, ESP handoffs, and lists that should have been cleaned months ago.

This is not a big-company job with a narrow lane. You will ship, talk to users, fix what breaks, and help decide what we build next. We move quickly because we have to — and because the people here prefer momentum over process theater.

What it's like here

Small team, real ownership

Everyone is close to the product and the customer. You won't disappear into a org chart — you'll see your work in production and hear about it when it helps (or when it doesn't).

Ship fast, learn in public

We deploy often, keep scope tight, and treat feedback as fuel. Perfectionism that blocks shipping is a luxury we don't have; thoughtful iteration is how we win.

Customers are part of the loop

When something breaks at 4pm, someone on the team answers. When a marketer can't map their columns, we get on a call and figure it out. Product and go-to-market aren't separate planets here.

Bootstrap energy

No slide decks about slide decks. We build what customers pay for, say no when we need to, and stay lean on purpose. If you've thrived at an early startup — or wish you had — you'll recognize the rhythm.

How we work

  • Remote-first, async-friendly, with live working sessions when a customer or launch needs it.
  • Direct access to founders and builders — short feedback loops, no layers of approval for every fix.
  • High trust and high accountability: you'll have room to run, and we expect you to use it.
  • Honest about tradeoffs. We'd rather tell a customer the truth than oversell what the product does today.

Open roles

Engineering · Full-time · Remote

Junior Software Engineer — Campaign Platform

Apply

Help build the core product: CSV ingestion, contact library, AI-assisted segmentation, copy guardrails, and export into the senders marketers already use. You'll write code that ships to real users this week — not next quarter.

You'll join as a builder on a lean product team. That means features, bug fixes, customer-reported edge cases, and the occasional "this CSV has seventeen different spellings of Company Name" fire drill. We don't have a platform squad and a growth squad — we have people who care about the product and the people using it.

What you'll do

  • Ship features across our Next.js app, API routes, and Postgres-backed workflows — from UI polish to data model changes.
  • Improve CSV ingestion, column mapping, deduplication, the contact library, and campaign export paths.
  • Work on AI-assisted segmentation and copy generation with guardrails marketers can trust — human review stays in the loop.
  • Investigate production issues, write clear fixes, and leave the codebase a little better than you found it.
  • Join customer calls occasionally when engineering context helps — or when something you built needs a human explanation.
  • Participate in product decisions: what's worth building, what's a workaround, and what should wait.

What we're looking for

  • 0–2 years of professional software experience, or strong personal projects and side builds you can walk us through.
  • Comfort with TypeScript/JavaScript and genuine interest in full-stack web development.
  • Evidence you've shipped something — even small — without a committee signing off on every line.
  • Curiosity about data quality, marketing workflows, and tools non-engineers actually enjoy using.
  • Clear written communication. You'll explain tradeoffs in Slack, not just in standup.
  • Calm under small-team pressure: priorities shift, customers write in, and we adapt without drama.

A typical week

Morning might be a PR review and a bug from a customer's upload. Afternoon could be pairing on a new filter UI or tightening an export column. You'll rarely wonder what you're supposed to be doing — the roadmap is short and the feedback is direct.

Nice to have

  • · Experience with React, Next.js, SQL, or REST APIs.
  • · Side projects involving CSVs, email, CRMs, automation, or LLM-assisted tools.
  • · You've been the person who fixed prod on a Saturday and didn't make it someone else's problem.
  • · Interest in MarTech, lifecycle marketing, or the messy reality of contact data.

Implementation & Growth Manager

Apply

Own the journey from first CSV upload to first trusted export — and help the right teams become long-term customers. Part onboarding, part solutions consulting, part sales: you're the person who makes Signal Send click for marketers who don't have time for another tool that overpromises.

You're the bridge between what we built and what a marketing team needs today. That means live demos, working sessions, troubleshooting messy data, and turning objections into product feedback. When a prospect says "our list is a disaster," you don't flinch — you roll up your sleeves and show them a path forward.

What you'll do

  • Run onboarding for new accounts: data mapping, audience strategy, protect/setup choices, and export into their ESP.
  • Lead discovery calls and product demos — show the workflow, not a generic slide deck.
  • Handle inbound interest: qualify fit, explain limits honestly, and help good-fit teams get to value fast.
  • Be the voice of the customer internally — clear, specific feedback that engineering can act on.
  • Document playbooks when you answer the same question twice: objection handling, CSV prep, common ESP exports.
  • Partner on lightweight growth experiments: outreach hooks, case-style writeups, referral moments from happy users.
  • Jump on issues when a customer is stuck — even if it's "just" a spreadsheet formatting problem.

What we're looking for

  • 2+ years in customer success, solutions consulting, implementation, account management, or a sales-engineer-adjacent role.
  • You've worked on a small team where you wrote the doc, ran the call, and updated the CRM entry yourself.
  • Comfort talking to marketers about lists, segments, copy, compliance nerves, and send workflows — not just feature lists.
  • Strong live communication: you can share screen, think aloud, and stay calm when a demo goes sideways.
  • Organized and proactive — you follow up without being chased and you close loops.
  • Bias toward action over process. You'd rather get a customer unblocked than schedule a sync about syncing.

A typical week

One day you're onboarding a lifecycle marketer through their first segment plan; the next you're on a call with a founder evaluating us for their team. You'll carry a short list of active accounts, know where each one is stuck, and ping engineering when something is a product gap vs. a training gap.

Nice to have

  • · Background in email marketing, lifecycle marketing, demand gen, or MarTech.
  • · Hands-on experience with ESPs (Klaviyo, Mailchimp, HubSpot, Customer.io, etc.) or CSV-heavy ops.
  • · You've sold or implemented B2B software where the buyer was skeptical and the data was ugly.
  • · Comfort writing short, clear emails and internal notes — no corporate fog.
