Job description

Join Reach as a Software Engineer

This is a chance to build the product that will define how companies grow in the AI era.
You’ll build the core systems that power Reach’s AI agents, the autonomous systems that execute complex growth strategies for some of the best tech companies in the world. This is not a “call APIs and wrap them in a UI” role. You’ll be designing the architecture, data pipelines, and agent orchestration that make our product actually work.
This is a ground-floor opportunity to join a scrappy, ambitious, and lean founding team with exceptionally high standards. You will define our technical trajectory and shape the very fabric of our company!

About Reach

At Reach we’re building the operating system to help companies monitor and control their visibility in AI search. We built a proprietary platform that combines our software, custom AI agents, and forward-deployed experts from the top 1% in organic growth (SEO & AEO), to help companies show up when buyers are researching and comparing solutions on Google and inside AI search engines like ChatGPT and Perplexity, and turn that visibility into pipeline and revenue.

We passed $1M ARR in record time, basically bootstrapped, and we’re now scaling to $10M ARR. We’ve been doing this for companies like ColdIQ ($7M ARR, #1 Clay worldwide sales agency), Indie Campers ($140M+ ARR), Carro, Fidelidade, Fraudio, Noxus and others.

A few recent results:

• Grew Indie Campers’ revenue attributed to AI search by +1,318.62% YoY (14x) and organic search revenue by +7.85% YoY across 2025, delivered during a full website migration. Read the case study.

• Helped ColdIQ influence $506K in signed contract value from organic and AI search in ~4 months, making SEO and AI search their #1 traffic source with organic traffic up 7.3x. Read the case study.

• Took Carro from a 0% to 34.58% AI citation rate (4.5x the nearest competitor) and the #3 most-cited domain in their category, now consistently closing 7-figure deals sourced from AI search. Read the case study.

You can see more of the results we drive for our customers here.

We’re turning services into software to disrupt the $100B+ SEO/AI Search market, which will get drastically bigger as search behavior shifts to AI and ad budgets follow.

“The global SEO and AEO services market will grow to $171 billion by 2030 from $81.4 billion last year” — Wall Street Journal

The team

We’re a team of founders, AI engineers, and SEO & AEO specialists passionate about creating a category defining company that moves fast and has fun doing it.

Here’s a look at what life on the team is like. This is our latest company retreat:

Our founders have a proven track record of building and scaling fast growing tech companies. Jose Velez (CEO) was the solo founder & CEO of Rely.io, an internal developer portal used by top engineering orgs like ESPN Bet and Feedzai, and launched AI products that reached #1 Product of the Day and #1 AI Product of the month on Product Hunt. He raised $3.6M from top-tier firms like J12 Ventures, Shilling Capital Partners, Techstars NYC, and TheVentureCity, as well as from notable angels.

Bernardo Ferreira (founding AI search strategist) led the strategy behind more than 250M organic visits and €100M in revenue attributed to SEO at Worten (think Iberian Amazon) in 2024.

Location

We care deeply about building things together, in person.

The core team is in Lisbon working out of our office with a focus on speed and collaboration, and we’re opening our second hub in NYC. The best ideas happen at the whiteboard, not in a scheduled Zoom call.

We’re a small team moving fast, and we need engineers who think like product builders, people who start with the customer problem, then figure out the engineering solution.
You’ll be one of the first engineers on the team. You’ll own features end-to-end, from the first line of code to production. Ownership is the default here. You’ll talk to users, ship fast, break things sensibly, and help shape how we build.

What You’ll Work With

• Frontend : React, TypeScript

• Backend : Python

• AI/Orchestration : LLM integrations and AI-powered features

• Infrastructure : Cloud

• Database : Relational and in-memory datastores

What We’re Looking For

• Product-first engineering mindset You think about problems as customer problems first. You ask “should we build this?” before “how do we build this?” You care about the outcome, not just the output.

• Strong engineering foundations You understand how software actually works, data structures, system design, APIs, databases. You have solid instincts and the ability to reason about tradeoffs.

• Fluent with AI-assisted development You use AI coding tools every day. You know how to get the most out of them, where they fail you, and when to trust your own judgment over theirs.

• Full-stack generalist You’re comfortable moving across the stack. You bring enough depth to go deep when needed, enough breadth to keep moving when context shifts.

What Good Looks Like

• You’ve shipped real products that real people use

• You have at least 3 years of professional engineering experience

• You have opinions about how software should be built

• You get excited about problems, not just solutions

• You’re direct about what you know and what you’re still figuring out

• You’re based in Lisbon or willing to relocate

The Honest Part

• This is an in-office role, five days a week — Lisbon. We believe great early-stage teams are built in the same room.

• The product is early. Some things are rough. That’s the opportunity.

• You’ll wear multiple hats and that won’t change for a while.

*Our job titles may encompass various career levels, and the actual base pay for this position will be determined based on multiple factors including training, transferable skills, work experience, business requirements, and market conditions. Additionally, this role is eligible for equity and comprehensive benefits.
