• Manage and optimize the Upwork profile and positioning
• Track outreach and conversion metrics: proposals sent, replies, interviews, calls booked, win rate, and revenue
• Suggest improvements to positioning, pricing hooks, profile, and messaging based on what is converting

What we're looking for

• Proven lead generation experience on Upwork
• Strong written English (B1+) — proposals need to read clearly and persuasively
• Understanding of UX/UI and WordPress services enough to speak to them credibly in proposals
• Sharp judgment for spotting good clients and avoiding time-wasters
• Organized, self-managing, and consistent with daily outreach
• Comfortable with metrics and reporting on pipeline performance
• Nice to have: experience with LinkedIn, Behance, or Dribbble outreach

Details

• Remote, flexible hours
• Freelance / contract — base + bonus per closed lead or project is negotiable
• Ongoing role with room to grow as the pipeline scales
• Paid vacation: 18 work days (excluding weekends)
• 10 days of paid sick leave

About the project
We’re working with a US-based (New York) proptech/govtech startup building the system of record for NYC affordable-housing compliance — a platform that takes a housing project from approval, through the lottery, to staying compliant year after year. Their AI review pipeline is already in production, processing real applications for real buildings. Lots of messy real-world documents, deterministic regulatory logic, and an AI layer that does the volume while experts handle exceptions.

It’s a long-term, stable cooperation with a small, high-ownership, high-collaboration team.

Cooperation

• GIG or B2B contract
• Full-time, long-term

• Remote, US-market focus

   

What you’ll do

• Own features end-to-end: spec, data model, migrations, backend services, pipelines, and UI
• Build LLM-powered document intelligence (extraction, classification, gap detection) over messy real documents — scans, spreadsheets, handwriting
• Design and run eval loops that make AI shippable: golden datasets from expert feedback, regression guards in CI
• Draw the line between AI and deterministic code — LLMs classify/extract/suggest; anything filed with a regulator runs through pure, unit-tested policy logic

• Ship Python services (FastAPI, Postgres, event-driven) and React/TypeScript frontends

   

Requirements

• 5+ years building and operating production software (senior product engineer)
• Strong Python (FastAPI, Pydantic, SQLAlchemy, Postgres)
• Real, hands-on LLM/GenAI experience: prompt pipelines with structured outputs, evals, OCR/document processing, agents — features that survived real users
• Frontend with React + TypeScript
• AI-native workflow: you use AI/coding agents to write most of your code and know how to verify their output
• Comfortable with ambiguity and defining fuzzy problems yourself
• Rigorous engineering: TDD, audit trails, verification

• English B2+ (comfortable communicating with the team)

   

Nice to have

• Proptech, fintech, govtech, or legaltech (regulated, document-heavy domains)
• Event-driven architecture (outbox pattern, streams, idempotent consumers)
• Experience migrating a business off a legacy system while it stayed live (e.g. Salesforce)

• Built eval infrastructure or human-in-the-loop review systems

   

Interview process

1. Hiring manager screen (background, ownership, how you work with AI)
2. Coding screen — a realistic task from the domain (bring your AI tools)
3. AI system design — a loosely defined real problem
4. CEO conversation

We're looking for a Senior DevOps Engineer to join our current infrastructure team of 4 engineers. You'll take ownership of how we build, deploy, and operate our cloud platform. We’re actively investing in modernization: migrating to a fully cloud-native architecture, improving compliance posture, and moving toward platform self-service for our development teams.

Our client, Miaplaza, is a US-based company with team members across multiple countries and cultures. We value transparent communication and expect everyone to collaborate respectfully and effectively across differences.

We have legacy systems (self-hosted, on-prem, limited scalability etc.) but we are transitioning to modern architectures, hosted services and cloud-native. The split between legacy and new work varies by period, but you should be comfortable working across both, bringing modern practices to new systems while pragmatically maintaining and migrating older ones.

A core goal of the modernization effort is to consolidate and shrink the stack: replacing legacy tooling with modern equivalents, adopting managed services where they make sense, and reducing the operational surface the team has to maintain. Every migration decision is measured against whether it lowers the daily burden on the team.
 

What You'll Work On:

Cloud Infrastructure & IaC

• Design, build, and maintain infrastructure on GCP (primary) and AWS (supplementary) using Terraform
• Drive the ongoing cloud migration - moving on-premise workloads to GKE with a container-centric approach, and evaluating managed/SaaS alternatives where they make sense over self-hosted

CI/CD & GitOps

• Maintain GitLab CI/CD pipelines and operate GitOps workflows - FluxCD for infrastructure delivery, ArgoCD for application deployments
• Work within a bi-weekly release cadence with a published schedule. Our CI pipeline is an evolving process: continuously improving validation, security scanning, and automation

Observability & Reliability

• Operate and improve our observability stack; build alerting, dashboards, and runbooks
• Participate in blameless postmortems - we focus on learning, not fingerpointing
• Contribute to disaster recovery planning and backup validation

Security & Compliance

• Maintain and evolve security controls, scanning tooling, and compliance posture

Platform Engineering

• Move toward developer self-service and contribute to our reusable Terraform module library
• Help build out staging and development environments from the existing production blueprint
• Contribute to cost optimization - being mindful of spending across GKE, storage, and self-hosted tooling

Databases & Data Stores

• Operate PostgreSQL, MongoDB, Redis, and RabbitMQ

Networking

• Work with service mesh, load balancing, CDN/WAF, VPC architecture, and DNS management
   

Requirments:

• 5+ years of hands-on experience in DevOps, SRE, or Infrastructure Engineering
• Solid Terraform experience - you've written modules, managed state, and dealt with real-world drift and refactoring
• Production experience with Kubernetes (GKE preferred, EKS/AKS experience transfers well)
• Senior-level GCP knowledge - IAM, networking, KMS, GKE, CloudSQL, Secret Manager. This is our primary cloud, and you have deep expertise here.
• Experience with CI/CD pipeline design and operations (GitLab CI preferred) and GitOps (FluxCD or ArgoCD)
• Bash for automation and scripting
• Understanding of networking and Linux administration
• Familiarity with observability concepts - metrics, logs, traces, and how they fit together
• Proficiency in English (written and spoken) - English is our working language across all teams and time zones
• Comfortable working in a globally distributed, multicultural team 
   

Nice to Have:

• AWS experience - we use AWS for select services; cross-cloud experience helps
• Experience operating self-hosted observability stacks (Prometheus, Thanos, Loki, Grafana, Tempo, OpenTelemetry)
• Istio / service mesh experience
• Database operations experience (PostgreSQL, MongoDB, Redis)
• Python experience
• Identity and access management - SAML/SSO, OpenID, OAuth with enterprise identity providers
• Security scanning and compliance tooling
• KEDA or event-driven autoscaling
• Experience migrating legacy infrastructure to cloud-native platforms
• Experience building internal developer platforms or self-service tooling
• Experience supporting .NET/C# application deployments
• Exposure to message brokers (RabbitMQ)
• Experience working in EdTech or mission-driven organizations
