Upwave (YC S12) | Senior Software Engineer | REMOTE (US) | Full-time | $150k-$175k + bonus/equity/benefits | https://www.upwave.com/job/8547924002/

Upwave builds brand measurement software for large advertisers, agencies, and media partners. We process high-volume ad exposure + survey/event data and turn it into brand lift, reach validation, optimization recommendations, and AI-assisted analysis for enterprise marketers.

We're looking for a senior full-stack/backend-leaning engineer who likes owning real production systems end to end. The strongest candidates for us tend to have concrete experience with JVM/Spring/Kotlin or similar backend systems, SQL/data modeling, AWS/Kubernetes/observability, and high-volume event or analytics pipelines. AdTech/MarTech/measurement experience is a plus, but not required if you enjoy learning messy business domains deeply.

The work includes building APIs and data pipelines, productionizing analytics/statistical workflows with Product and Data Science, improving reliability/performance, and building AI-powered customer experiences around our internal AI analyst, Bayes. Stack includes Kotlin/Java, Python analytics services, React, MySQL, DynamoDB, AWS, Kubernetes, Terraform and LLM orchestration.

We're profitable/growth-stage, remote-first in the US, and engineering-led: high velocity through focus and leverage, not crunch. Interview process includes an in-person meeting.

FusionAuth | Principal Software Engineer, Senior Java Engineer - Cloud, Account Executive, Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.
