Prophet Town LLC | Various Software Engineering Roles | US – Remote and Hybrid | English fluency required | Full-time | $140K-$264K annual total comp (multiple)

We are a people-first, boutique tech agency creating on-demand teams and software solutions for long-standing clients. These clients trust us to practice engineering excellence as though we were members of their own staff. Our leadership team is ex-Fortune 100 with software engineering backgrounds: we’re still coding. Notable recent projects include a gigantic ERP migration for Anduril, and working with Surge Labs to help develop some of the frontier LLM models from the big guys themselves (yes, seriously). This is a remote-first agency, but some projects involve onsite work.

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.

For September 2026: our current work would especially benefit from from ai-forward senior engineering expertise that can design RL benchmarks, red-team model outputs, and create rubrics to evaluate and enhance the agentic coding capabilities of various frontier models. We received 216 applications in our August posting, and issued offers to approximately 10 (still following up with a few).

Applicants must meet a high bar - I intend to have a personal relationship with every hire. In return you’ll get:

  * Flexibility and a low-bureaucracy environment

  * Clients that won’t treat the vendor like “the B Team”

  * The chance to act as a code architect, not just implement tickets

  * Exposure to a wide variety of industries and modern     challenges

  * Me as your personal champion and advocate

Feel free to submit, even if you already did in the past.

Current roles available:

Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)

Tier 3 roles are typically 5-10 years experience with $140-$180K total comp. Tier 4 roles are 11-20 years experience, $210-$264K total comp. Higher tiers exist, and we always welcome exceptional applications.

Duets Network | Founding Engineer | REMOTE (US) | Equity + discretionary cash | ~10–15 hrs/wk

Duets Network is an AI-powered platform connecting startups and investors across the sports and entertainment industries. We are building a dynamic ecosystem that bridges founders, capital, and strategic partners to drive meaningful growth and collaboration at the intersection of technology and culture.

The initial product is built out, and we're now looking for a fractional Founding Engineer to guide the technical side moving forward: architecture, infrastructure, data/recommendation systems, security, and scalability.

Our founding team: CEO, ex-Universal Music Group; CBO, ex-Andreessen Horowitz. You'd work directly with the founders, with no existing engineering org, and would:

- Assess and improve the existing React / Node.js / PostgreSQL / AWS codebase and infrastructure

- Set engineering architecture, standards, and technical priorities

- Design the data + recommendation/scoring layer behind founder/investor/partner matching

- Build out DevOps, CI/CD, monitoring, and deployment processes

- Make pragmatic build-vs-buy decisions and coordinate external engineers/vendors as needed

- Serve as the primary technical team member, with real influence over the technology foundation and future engineering org

We're particularly interested in someone who has owned architecture end-to-end. Ideally with experience in matching, recommendation, ranking, or scoring systems. You should be comfortable explaining technical tradeoffs to non-technical founders and investors.

This is a fractional role (~10–15 hrs/wk), compensated with equity plus discretionary cash. It's a fit if you want the opportunity to be an early technical team member without a traditional full-time commitment. We're early-stage and moving fast, so you don't need to check every box, we're looking for someone curious, adaptable, and excited to build with us.

If interested, email team[at]duetsnetwork[dot]com with "Founding Engineer" in the subject line.

Mastra | Customer Engineer | REMOTE (AMER or EMEA time zones) | Full-time

Mastra is the open-source TypeScript framework for building AI agents (agents, workflows, memory, evals, tracing). From the team behind Gatsby, YC-backed,https://github.com/mastra-ai/mastra

We're hiring a customer engineer. Some companies would call this an FDE; we don't, because roughly half the job is shipping in the framework itself. The other half you're embedded with paying customers deploying agents to production: in their Slack channels and on calls, writing code in their repos, reviewing their PRs, working through architecture with their engineers. What you learn there comes back as bug fixes, features, and new primitives in Mastra. One of our current customer engineers is among the top bug-fixers in the entire codebase.

You should be a full-stack TypeScript engineer who has built agents and who can explain technical decisions clearly to engineers who haven't seen your code.

Remote. We have a lot of EU customers and response-time SLAs, so US Eastern/Central or EU hours work best.

Process: a call with Shane (co-founder/CPO, leads customer engineering), a conversation with a customer engineer, a 2-3 hour take-home, then you present it to us and get feedback.

Apply: {https://jobs.ashbyhq.com/Mastra/05172cb0-47ec-44f9-9fe8-07d4...} We get back to everyone.

Tecuity | Senior Software Engineer I | Hyde Park, UT (ONSITE preferred; will consider candidates who can commute in 1-2x/month) | Full-time | $90k-$135k

Tecuity has spent 20+ years building software for Secretary of State offices — state government agencies handling business filings and public records. Real filing deadlines, statutory requirements, and citizens who depend on the system working.

We're hiring a Senior Software Engineer I to own features end-to-end on a mature, multi-tenant .NET platform, typically supporting more than one client implementation at a time, each with its own database and release calendar.

Stack: C# / .NET 8 & .NET 10, ASP.NET Core, Web API, Entity Framework Core, MS SQL Server (heavy stored-procedure work), React + Redux front end, Git/PR workflow, Azure DevOps CI/CD.

AI-assisted development (Claude Code) is a standard, daily part of our engineers' workflow here, not a pilot program — you'll be expected to use it well and verify its output rather than just accept it.

Looking for 6+ years professional experience in C#/.NET and SQL Server. Government, regulated, or compliance-driven software experience is a plus.

Ideally we're looking for candidates who can work onsite from our Hyde Park, UT office, but we're open to Utah or Idaho candidates who can commute in once or twice a month for the right fit.

Email hr@tecuity.com with a bit about your background and a resume or for more information. See the full job posting at tecuity.com/careers

Xaira Therapeutics | Midlevel/Senior/Staff Engineers | Seattle or SF

Xaira Therapeutics is developing biological foundation models (not LLMs) to hit undruggable targets and cure disease. We've put together an incredible cross-disciplinary team of pharma veterans who have brought drugs to market, drug designers/AI scientists from Nobel laureate David Baker's lab, and engineers from tech in order to meet the moment and build a company to reimagine how drugs are made in the pursuit of better medicines. We're not a SaaS company, and the ultimate goal is to see the medicines we make delivered to patients.

I lead the engineering team and am hiring across multiple teams. There's:

- Research Engineering: work on a modeling team with the goal of making a model better. You think in tensors, understand what makes a kernel fast, and obsess over training throughput.

- X-Scientist: building an agentic copilot for drug development with access to our internal suite of tools. You have backend experience, have built tools for agents to interact with, and enjoy tinkering with agent harnesses.

- Data Engineering: we generate large volumes of data from our lab that provide critical feedback loops to our modeling efforts. You either hate or love lakehouses, have a preferred ETL orchestrator, and are intrigued by the problem of capturing data off of lab instruments.

- ML Platform: boy do we have some GPUs for you. Modeling teams need productive compute infrastructure, job scheduling, and numerous other affordances so that they can "just focus" on the model. You shudder at the words "falling off the bus", you have an opinion on how checkpoints should be recorded, and you've built tools that improve the modeling lifecycle.

Send me an email to apply: justin.yan@xaira.com Include a resume and tell me about something you've built that illustrates your skills.

About me. Senior backend engineer, ten years on the JVM. Since 2021 I have been one of the engineers behind LoverCraft, a US survival network that peaks at 1,500 concurrent players and holds 300 to 450 on a normal evening, with 30+ cross-server services spread across several Debian hosts. Team of three to five. My work is low-latency cross-server state over Redis, an economy with an audit row per transaction, JVM tuning, and end-to-end telemetry on ClickHouse. When a backend goes down mid-session, players notice in seconds and I am in the incident channel.

Before that, five years at Senior Sistemas building Java, Spring Boot and Angular for Kinross Gold, Petrobras, Banco BMG and Grendene. Intern to owning the software factory's architecture area.

Production work is closed-source under contract. The open-source side is on GitHub, written up on the site. Best fit: real-time or high-throughput backends, game and multiplayer infrastructure, platform work. English is fluent written, intermediate spoken.

Senzing (entity resolution SDK) | Platform Engineer | Remote (USA) | Full-time

Senzing builds enterprise entity-resolution SDK technology — an embeddable library that runs entirely inside customer infrastructure with zero data exfiltration. We're hiring a platform engineer to own the AWS infrastructure behind Placekey (our location-data subsidiary), a production API service running at scale.

Day one, this is a cloud/platform role: you'd own the operational health of Placekey's stack, close out post-migration hardening, and have real input on where the infrastructure goes next. Over time the role grows to include internal IT and systems work (Active Directory, endpoint/laptop provisioning, Tailscale, security) — so we're looking for someone who's happy owning things end to end, not only the glamorous layer.

Stack: EKS Fargate, Aurora PostgreSQL, S3, Lambda, Cloudflare, API gateway (Kong/AWS), Terraform, Grafana/CloudWatch/Datadog. Apps are Scala and Rust.

Looking for: 5+ years platform/cloud infra, production Kubernetes (EKS ideal), managed Postgres (backup/recovery/tuning), IaC, solid networking, strong Python/Bash. You don't need to be an expert on the IT/systems side today — but you should want to grow into it.

Remote anywhere in the USA. Competitive salary, full health/dental/vision, 401(k) match, flexible PTO.

To apply: email enghiring@senzing.com with your resume and a short note — tell us about a challenging production system you've owned end to end, including an incident where your monitoring missed something and what you changed afterward.
