Applied Research Engineer

  • Location: Remote
  • Department: Research
  • Employment Type: Full-time

What’s in it for you?

Paciva ships research into product on a short clock. Message intent classification, memory that survives across sessions, privacy protection that holds under scrutiny. These started as research questions and became features.

You would own that pipeline. The work is real research with a deadline and a customer at the end of it.

About the team and the opportunity

Be clear eyed about the field. Persistent memory and proactive behavior are no longer rare. Open source agents ship both, and several funded companies claim both. The work here is not inventing the category. It is accuracy, reliability, and doing it under handling rules strict enough that a regulated buyer signs.

Every experiment runs inside the commitments published in the trust center. Those commitments constrain the work by design, and holding to them is part of the job rather than an obstacle to it.

What the role covers

You run the research that becomes product. The current areas are message intent classification, memory that persists across sessions and resists poisoning, and redaction that protects sensitive information before it travels. You design experiments, set honest baselines, run error analysis, and hand results to engineering in a form they can ship. You identify patentable work and write it up for filing.

What you will work on

  • Improve classification accuracy and expand what the platform can recognize
  • Advance the memory layer, including how it stays fresh and resists poisoning
  • Run evaluations that separate real gains from noise
  • Build the privacy and redaction research that protects sensitive information
  • Identify patentable work and write it up for filing
  • Publish internal results that other teams can build on
  • Track the field closely enough that the company is never surprised

What we need from you

  • Graduate work or equivalent experience in machine learning, NLP, or information retrieval
  • Strong experimental discipline, including honest baselines and error analysis
  • Ability to ship research into production rather than into a paper
  • Comfort working inside strict data handling and governance rules
  • Clear writing for technical and non technical readers
  • Interest in behavior and language, not only in model architecture

Working at Paciva

About Paciva

Paciva is an early stage company with people in Miami, Florida and Austin, Texas. The team works fully remote. Pax is an executive assistant for individuals and a chief of staff to organizations. It connects to the services you already use and does real work end to end, rather than reporting back on what needs doing.

The company is founder led and privately held. Every role we post is a first hire for its domain, which means you set the standard rather than inherit one, and you work with the founders directly rather than through layers.

Compensation and benefits

Compensation is set by role scope, experience, skills, location, market data, and internal equity. Every role carries meaningful equity, because the person who builds a domain from nothing should own part of what they build. For sales roles, compensation combines base salary with variable incentive pay, and the target is stated as on target earnings.

We cover pay and benefits in full in the first conversation, before you spend time on a process. Ask early and we will answer.

Remote work and travel

Every role here is remote. Paciva has people in Miami and Austin, and the team works across time zones. That puts weight on clear written communication, ownership, practical collaboration, and dependable follow through. Most roles include occasional travel for team meetings, customer sessions, company events, or off sites.

How we hire

We read every application. If your experience does not match the list above but you have done work that shows you can do this job, put that at the top.

The process is short and the founders run it. You will spend time on a real problem from the role rather than a hypothetical, and you will meet the people you would work with every day, because there are not many of us. We tell you where you stand at each step and we do not leave anyone waiting.

You are welcome to use AI tools when you apply. We build them. What we want to see is your judgment, so tell us where you used a tool and what you changed about its output.

Accommodations and applicant privacy

If you need a reasonable accommodation to take part in any stage of this process, tell us. You do not need to share medical detail. We will work out what lets you participate fully.

For how we handle the information you send us when you apply, see our applicant privacy notice at https://trust.paciva.ai/

Paciva recruiters only contact candidates from paciva.ai email addresses. We will never ask for money, fees, or banking information at any point before your first day. If a message looks off, do not click anything in it. Come back to paciva.ai and check the open roles here.
