Email: luchenbrendan@gmail.com

Known for refactoring ruthlessly, hunting root causes, and fighting for the users often while talking with my hands.

Technologies: Are listed on my resume and gravitate around fullstack. To get past bad filters, I enumerate JavaScript TypeScript React Next.js Node.js Python Tailwind Linux Java Kotlin Android React Native Docker Git PostgreSQL GenAI AgentAI and Supabase.

Seeking: Bonus points for work in Health, Education, or Environmental sectors. Full remote is ideal, but Hybrid 40% in the Boston metro is fair game, and if you are still reading, have a wonderful day and make a stranger smile.

Statement: Hire me for versatility as a polyglot agnostic builder of stuff, mentorship capacity to strengthen your whole team, bulletproof optimism in a fast-paced and uncertain world, a low-maintenance and well-behaved ego, and the occasional classy dad joke (no, I don't have kids).

Eagle | Founding Member of Technical Staff | NYC (onsite) | Full-time | $150K–$300K + equity | https://www.eagleeng.com

We’re on a mission to radically transform the way we design and construct our built environment.

Backed by Lightspeed Venture Partners, Eagle acquires civil, structural, and MEP engineering firms and transforms them with applied AI. Our thesis: 85% of what engineers do is automatable, yet less than 5% has been touched by AI; the largest gap of any profession. By arming designers with frontier technology, our ambition is to build the most valuable, talent-dense engineering firm in the United States.

We're looking for our first members of technical staff. If you get excited about building from zero, get energized by direct access to users, and want to work in a problem domain that's barely been touched by AI, we'd love to talk.

SmarterDx | 150-250k+ + equity + benefits | Remote (US only) | Multiple roles | https://smarterdx.com/careers

SmarterDx builds clinical AI for one of healthcare’s most broken systems: how hospitals get paid for the care they actually deliver.

Our physician-designed clinical AI platform reviews the clinical record, understands the nuance of patient care, and helps hospitals capture appropriate reimbursement across the revenue cycle. The core problem is hard: messy clinical data, complex regulations, payer rules, medical reasoning, and real financial stakes. When we get it right, hospitals recover millions in earned revenue, reduce manual review burden, and keep clinical and revenue teams focused on higher-value work.

We’ve hit serious scale while keeping the team unusually strong and technical: MD/data scientist hybrids, Stanford LLM researchers, former Google and Amazon engineers, former ASF board member, and others who are among the best in their fields. Many teammates have been here since we bootstrapped to $1M+ in contracted revenue before raising capital.

In 2025, SmarterDx became part of Smarter Technologies through a $1.1B deal with New Mountain Capital, reaching unicorn status while continuing to operate with the autonomy, urgency, and product velocity that got us here. Before that, we raised $71M from Floodgate, Transformation Capital, and Bessemer, including a $50M Series B. We have real product-market fit: 85+ health systems, 300+ hospital sites, rapid customer growth, and 150% YoY headcount growth (currently at ~500). Now we’re scaling the platform.

We have PMF, and it's time to scale! For more and to apply, see https://smarterdx.com/careers

TrakPro | Senior Rails Engineer | REMOTE (overlap with Ireland 9–5 GMT) | €48–60k/yr

We're a construction payment management SaaS based in Ireland. Main contractors and subcontractors use us to track subcontracts, payment applications, and retentions — replacing the spreadsheets they currently rely on. Small team of 5 (3 in engineering), customers in Ireland and the UK.

We're hiring our 3rd engineer. You'd own features end-to-end alongside our two existing engineers. Async-first, fully remote, real product ownership.

What we want: - 5+ years shipping Rails in production - Daily Claude Code or Codex user with a real workflow, your own skills/hooks/commands, opinions on when to override the agent, habit of reviewing AI output as critically as a junior PR - Strong written English, calm under customer-facing pressure

Stack: Rails 8, Hotwire (Turbo + Stimulus), Postgres, RSpec, AWS, GitHub Actions

Apply: product-hiring@trak-pro.com please share your resume and a one paragraph note on your AI workflow (tools, skills, hooks, or commands you've built). https://trak-pro.com

Kepler | Full Stack Engineer | New York, NY | ONSITE | $230K-$260K + equity

We're building the trust layer for AI in high-stakes industries. https://kepler.ai

LLMs hallucinate, so they can't be the thing producing your numbers. In Kepler, the LLM orchestrates (decides what data to gather, what to compute, how to structure the output), but the model never touches the data itself. Every actual value flows through deterministic code pipelines with provenance metadata back to source. Verification loops cross-check outputs before users see them.

We started in finance because tolerance for wrong answers is zero. First product is a research platform for buy-side analysts: pull comparables, build models, research filings. Same architecture extends to chemicals, legal, healthcare. Models are commoditizing fast; the trust layer is what's missing.

If you want the deeper architecture writeup, Anthropic just published a case study on Kepler: https://claude.com/blog/how-kepler-built-verifiable-ai-for-f...

What you'd build:

- Source-explorer UI that traces any value back to its exact origin in the original document - Extraction pipeline for a data source we don't yet handle, with provenance and verification from day one - Agent orchestrator that handles partial failures so a bad extraction from one source doesn't block parallel work - Verification rules that cross-check values across multiple sources and surface conflicts with provenance on both sides

Stack: Rust backend (orchestration, extraction, computation), TypeScript/React frontend, PostgreSQL, AWS. Model-agnostic, currently Claude + GPT. We don't require Rust experience; we hire on fundamentals.

Looking for 5 years production experience, strong in TypeScript/React, comfortable in backend work. Bonus if you've built systems where correctness mattered (payments, data infra, healthcare, anything where a wrong output has consequences). Distributed systems basics: concurrency, fault tolerance, retries, idempotency.

Founding team is 40+ combined years at Palantir building Foundry's core systems (Ontology, Fusion, Workshop, FoundryML). CEO scaled a data company to $15M ARR, sold it, then ran Business Engineering at Citadel. Backed by founders of OpenAI, Meta AI Research, MotherDuck, dbt Labs.

In-office NYC.

MixRank (YC S11) | Software Engineers | 100% REMOTE (Global) | Full-Time MixRank processes petabytes of data every month from web crawling. We have hundreds of customers using our data products including Google, Amazon, Facebook, Intel, and Adobe, across industries including Finance, Recruiting, Sales, Marketing, and Security. We’re a fully-remote company with a global footprint in over 20 countries. We're growing, profitable, employee-owned, no dependence on outside funding. Applicants from all geographies and backgrounds are welcome. We are looking for passionate individuals for whom programming is not just a job but it’s something they love to do. We're obsessed with computers, programming, big data, databases, compilers, hardware, math, data science, and the internet. Does this sound like you? Please apply to join our team. Our code base is very friendly to new contributors. You'll have a fully-functional development environment within hours (fully automated) and be pushing commits on your first day. Deployments to production happen multiple times per day and finish in less than 2 minutes. Effectively all of our codebase is written in Python, Rust, SQL, Javascript/TypeScript, and Nix. The core technologies you'll need familiarity with to be productive are Python, PostgreSQL, Linux, and Git. We operate at a larger scale than typical startups. We operate two datacenters with high performance servers we've built that are capable of dealing with the volumes of data we process. We've implemented our own distributed file system. We do full-scale web crawls. We download and perform static analysis on the entire universe of Android APKs and iOS IPAs that are published. Unlike a typical startup where you'll spend half of your time in meetings, and the other half fixing bugs from Jira tickets— at MixRank you'll get to challenge yourself with difficult technical problems that will help you to grow as an individual.

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

FunnelStory | Principal Engineer, AI Systems | Remote (India) | Full-Time | funnelstory.ai

FunnelStory builds a queryable context graph over enterprise data — the infrastructure layer that lets AI agents reason over live customer intelligence. We've built a federated query engine purpose-built for agents, ML models from scratch in Go (health scoring, cohort expansion, process mining, Markov chains, Genetic Pareto optimization), and on-prem deployment infrastructure for enterprise customers. All on a deterministically tested backend.

We need engineers who go deep. The kind who read academic papers to build something novel, then hunt down a performance bottleneck five layers deep in the stack. Go is preferred but not required. Strong math and systems engineering background is a plus. What's required: ability to solve hard problems, use AI tooling to add real value (not slop), and drive work forward independently.

Please reach out to me directly at preetam @ funnelstory.ai with "HN" in the subject.
