Build the next generation of rental real-estate

HiFriendz is an AI-native company: AI agents do the mechanical building, humans own the judgment. We’re hiring a lean Product & Engineering team to serve 2,000+ sales agents and thousands of renters every day.

Why join HiFriendz

This isn’t “a traditional dev team that uses AI.” It’s the inversion of the old software org — most human energy goes into judgment and verification, while AI agents handle the implementation.

A true AI-native company

AI agents do the mechanical work; humans own the judgment — architecture, deciding what to build, and verification. You work at the highest-value layer.

Real impact, real users

The product serves 2,000+ sales agents and thousands of renters every day. Everything you ship runs in production.

Small team, big leverage

No bloated developer pyramid, no heavyweight SDLC ceremony. A lean team + AI, with everything flowing through one ticket system.

Work on the frontier

Hands-on with agentic coding, LLMs, and quality/eval loops — the skills shaping software from 2026 onward.

Open positions

Senior roles require real experience building production systems; we also have an entry-level QA track. Expand each role for the full job description.

Product Manager

Roadmap owner & approval gate

Ho Chi Minh CityFull-time4+ years experience

Own the product roadmap and decide what to build. You're the upstream decision-maker and the human approval gate — agents and engineers build fast; you decide what's worth building and sign off on what ships.

  • Own & prioritize the entire roadmap for a platform serving 2,000+ sales agents.
  • Be the human approval gate: sign off on PRDs, acceptance criteria, and release notes.
  • Work daily with one senior engineer + AI agents through the ticket system.
View full job description

Own the product roadmap and the “what to build” for an AI-native real-estate platform that 2,000+ sales agents and thousands of renters depend on daily. In an AI-native shop the bottleneck is deciding what to build, not writing code — so you are the upstream decision-maker and the accountable human approval gate. Agents and one senior engineer build fast; you decide what is worth building and sign off on what ships.

What you’ll do

  • Own and prioritize the product roadmap end-to-end; turn business goals from leadership, sales, ops and CS into clear specifications and acceptance criteria.
  • Be the human approval gate — final sign-off on PRDs, acceptance criteria, roadmap changes and release notes (AI agents may draft them; you approve).
  • Run discovery with the 2,000+ sales agents, the data-entry, CS and ops teams; convert real workflows (listings, search, deposits, CRM) into prioritized tickets.
  • Define success metrics, instrument them, and make evidence-based scope and trade-off decisions.
  • Keep the ticket queue triaged and unblocked; partner daily with the senior engineer and AI agents.

Must-have (real production experience)

  • 4+ years in product management shipping B2B/SaaS or marketplace software that real users depend on in production — not prototypes or internal demos.
  • A demonstrable track record owning a roadmap and shipping features end-to-end with measurable business outcomes.
  • Excellent written specs and acceptance criteria; fluent working in a ticket-driven workflow (Jira / Linear / equivalent).
  • Data literacy: you define metrics, read dashboards, and make calls from evidence.
  • Comfortable using AI tools / agentic workflows, and willing to be the accountable human who reviews and signs off on AI-drafted artifacts.
  • Strong written English (our technical docs and specs are in English); Vietnamese is a plus for local stakeholders.

Nice-to-have

  • Real-estate / proptech, CRM, or two-sided marketplace experience.
  • Experience shipping LLM-powered features (chat assistants, search, evaluation loops).
  • Technical background — can read a data schema and reason about APIs.

Senior Software Engineer

Architecture, the agent harness & the merge button

Ho Chi Minh CityFull-time5+ years experience

The senior engineer who owns system architecture, the agent harness, and the merge button for the whole platform. You don't hand-write every feature — you direct AI agents to build, then review for architecture and own everything that reaches production.

  • Own architecture across a Next.js + Firebase + OpenSearch stack.
  • Build & harden the “agent harness”: workflows, guardrails, CI, safety rails for AI.
  • Own the final review & the merge button — humans own deployed code.
View full job description

You are the senior engineer who owns architecture, the agent harness, and the merge button for the whole platform. You will not hand-write every feature — you direct AI coding agents to build, then review for architectural soundness and own everything that reaches production. This is a high-leverage, high-ownership role: think “agent wrangler”, not “ticket cruncher”.

What you’ll do

  • Own system architecture and high-judgment technical decisions across a Next.js + Firebase + OpenSearch stack.
  • Build and harden the agent harness — the workflows, prompts/skills, guardrails, CI and safety rails that let AI agents ship code safely.
  • Own the final code review and the merge button: humans own deployed code. Review for interfaces and architecture, not style.
  • Own production reliability, security gates (customer PII, deposit/money flows), data migrations, and release approval.
  • Set the verification bar together with the test engineers; enable shift-left testing so agents self-correct against tests before code reaches the pipeline.

Must-have (real production experience)

  • 5+ years building AND operating production web systems that real users depend on — you have owned services in production, not just written code.
  • Deep TypeScript and modern React / Next.js (App Router) experience.
  • Strong backend: Node.js, serverless / cloud functions, a real production database (Firestore / NoSQL or SQL), and pragmatic API design.
  • Cloud + DevOps: CI/CD, deployments, observability and incident response (we run Firebase App Hosting + Cloud Functions).
  • You have made architecture decisions and lived with their consequences; you reason clearly about data models, security and scale.
  • Hands-on, enthusiastic user of AI coding agents (Claude Code / Codex / Cursor-style) — you can direct, review and correct AI-generated code at a senior level.
  • A security mindset appropriate for a system handling customer PII and deposits.

Nice-to-have

  • Firebase / GCP and OpenSearch / Elasticsearch (search relevance) in production.
  • AWS database experience (RDS / Aurora / DynamoDB) and other production data stores.
  • LLM application engineering: RAG, evaluations, agent orchestration.
  • Prior lead / staff role, or having solo-owned the technology of a real product.

Test Engineer

The human quality gate for AI-generated code

Ho Chi Minh CityFull-timeMultiple openings

Verification is the primary human quality gate for AI-generated code at HiFriendz. You don't just run scripts — you define what “correct” means before agents build, hunt the edge cases AI misses, and gate what ships to 2,000+ sales agents and their customers.

  • Own test specs & acceptance — define correctness before the agent builds.
  • Adversarial, edge-case and exploratory testing of AI-generated changes.
  • Evaluate our own AI behavior (Sofia, ticket triage, listing extraction).
View full job description

Verification is the primary human quality gate for AI-generated code at HiFriendz — and the dominant engineering role on the team (we are hiring several). You are not a script-runner: you define what “correct” means before agents build, hunt the edge cases AI misses, and gate what ships to 2,000+ sales agents and their customers.

What you’ll do

  • Own test specifications and acceptance verification — define correctness before an agent builds a feature.
  • Adversarial, edge-case and exploratory testing of agent-generated changes across the listings, search, deposits/CRM and customer-support workflows.
  • Build and maintain automated tests (unit / integration / e2e) and the regression gates that agent code must clear before merge.
  • Manual UAT of real Vietnamese real-estate workflows; reproduce, triage and report issues clearly and actionably through the ticket system.
  • Behavioral evaluation of our own AI — Sofia answer quality, ticket-triage accuracy, listing-extraction accuracy: “does the agent behave consistently”, which is distinct from functional correctness.

Must-have (real production experience)

  • 2+ years testing software that runs in production with real users — you have caught issues that genuinely mattered.
  • Strong test design and adversarial / edge-case thinking; you reason about intent, not just steps.
  • Hands-on automation: experience with an e2e/integration framework (Playwright / Cypress or similar) and the ability to write test code (JavaScript / TypeScript preferred).
  • Clear written bug reports and reproductions; comfortable in a ticket-driven workflow.
  • Detail-oriented, product-minded, and healthily skeptical of code that merely “looks right”.

Nice-to-have

  • Experience testing AI / LLM features or evaluating model outputs.
  • API testing, CI test pipelines, performance or accessibility testing.
  • Familiarity with Vietnamese-language products and the real-estate / payments domain.

View full job description

An entry-level role for someone starting their software-testing career. At HiFriendz, verification is the primary human quality gate for AI-generated code — so it's one of the best places to learn what great QA looks like. You'll work alongside our senior engineer and experienced testers, learning to think adversarially about software that 2,000+ sales agents and their customers rely on every day.

What you’ll do

  • Write, run and maintain test cases for features and bug fixes under guidance.
  • Do manual and exploratory testing across the listings, search, deposits/CRM and customer-support flows; reproduce and report issues clearly through the ticket system.
  • Learn to read acceptance criteria and verify changes against them — including AI-generated changes.
  • Help check our AI's behavior (e.g. Sofia answers, ticket triage) and flag inconsistencies.
  • Grow into automated testing and ownership of regression areas over time.

Must-have (real production experience)

  • A genuine interest in software quality and an eye for detail — you notice when something is “off”.
  • Basic understanding of how web and mobile apps work, and the drive to learn testing methodically.
  • Clear written communication for bug reports and reproduction steps.
  • Comfortable working in a ticket-driven workflow and with English-language documentation.
  • 0–1 years of experience — recent graduates and career-switchers welcome. An internship, personal projects, or a testing course is a plus but not required.

Nice-to-have

  • Any exposure to test automation (Playwright / Cypress / Selenium) or scripting (JavaScript / TypeScript / Python).
  • Curiosity about AI / LLMs and how to test them.
  • Familiarity with Vietnamese-language products and the real-estate / payments domain.
