Pre-Series A

Tierra keeps people safe by making crime data actionable. We empower those who are most at risk and make their day-to-day lives safer. We work closely with companies and governments who commit large amounts of resources to safety but have historically seen poor results. Our initial focus is Latin America.

Our product provides tools to monitor and analyze security data and allow for decision making with street level precision.

We’re looking for people who want to work on projects that matter. Creating solutions in this space is non-trivial. Our data sets are very large (ever tried to render 1 million data points on a Google map and suggest safe routes?) and the work we do will quickly start to affects hundreds of millions of people on a daily basis.

We are well funded by some of the best investors and have are in alpha with several name brand Fortune 500s. This is a truly diverse, and inclusive team.

Why join us?
  • Market pull. We have a 100% conversion rate of our sales conversation. Everybody is struggling with safety and people are desperate for solutions. We have some of the largest companies in Mexico as initial customers and they are actively referring others. It is a true multi billion market.

  • Top investors and advisors. We have raised money from some of the best investors and angels in the world, including General Catalyst, Propel, early Stripe employees, and Dropbox executives. People helping us not just because it is a good business opportunity - the problem we are solving needs to get solved and people realize it.

  • Long term defensible moat. It took 4 years to secure the data sources which power Tierra. This data is non public and we will soon have the largest dataset in Mexico. The methodologies and corporate/ private sector connections that we have built up are proving to scale beyond Mexico. We expect that we'll be able to generate the largest security dataset in LATAM in the next few years.


Engineering at Tierra
Engineering team and processes

We're a small engineering team, covering both front-end and back-end and working off of weekly releases, weekly sprints, and weekly triages. Design is communal, though often led by the head of product. Everyone in the company helps test releases, acting as company-wide QA. All engineering projects are maintained within Github's issues tracker, and we occasionally use Asana for larger roadmaps. When the team size grows we'll be using pull requests both for reviews and to manage code updates. Every engineer can lead a project, especially if it reflects a strong desire and capability.

Technical Challenges

Turns out mapping large data sets is hard. Especially if you want to provide a set of robust tools to manipulate the maps by end users. Google Maps API´s and other non professional GIS services degrade pretty quickly when you pump several million data points through them. There are patches that help scale past some of those challenges but the need to provide high quality consumer experience with complex mapping requirements means we end up building a healthy amount of tech in house. We are working with sufficiently complex data and diverse usage patterns that performance is a real challenge both architecturally and operationally.

The demand for the product will rapidly become an issue. The pain around security is such, that when we launch, our product is going to be pushed quickly to levels that will require hardening and clever scaling.

Other than that, the data and tools we surface truly alter user behavior. When we get it right, this saves lives. That responsibility is felt by all of us.

Projects you might work on
  • Implementing a custom routing algorithm taking security into consideration, in addition to more traditional factors such as traffic, timing for route, etc.

  • Build support to selectively refresh a map such that queries are only made for the parts of the map newly exposed. Make this fast and work seamless on both web and mobile.

  • Rapidly ingest new data and deploy learning algorithms to automatically reject, merge, or add data points. Over time this will became a defacto fraud management as we open to consumer level reporting of crime data.

Working at Tierra

We work on improving safety for millions of people. That matters, and makes our day-to-day job meaningful. We are a tight-knitted team with a strong sense of camaraderie, and always appreciative of a good joke. We are female led, diverse and multicultural. Teaching and learning is part of the job.

Travel

We are a distributed team. For folks who want to be colocated we do have offices in the tech Mecca, San Francisco, and one of the most vibrant cities in the globe, Mexico City . Others work fully distributed, from DC, and NYC. Travel is infrequent but an option if people want to work together or if something is easier solved in person.

Flexible Hours

Productivity is what matters at Tierra, not face time. We have a daily virtual stand up but beyond that people can organize their days according to their preferences. For those that come to an office people tend to be there from 10am. People work hard and many days go late, but a portion of the team has families with kids so hours are spent where they make sense.

Work from Home

For those that work from one of our offices, Friday is a work home day. This is one of several structural things we do to make sure we continue to develop a strong distributed culture.

Company Retreats

We are planning our first retreat this autumn at the Mexican Pacific.

Free Food

We don't have fancy chefs, but we certainly serve incredible home-cooking food in our Mexico City office twice a week. Meals are made with organic ingredients locally sourced.

Health Insurance

We provide full medical health insurance.

Generous Vacation

We have unlimited vacation policy!
