About Masthead Data

Masthead Data is a data observability and BigQuery cost optimization platform built on a zero-data-access architecture — we operate exclusively on audit logs and metadata, and never touch our customers' underlying data. That constraint is our core differentiator and shapes every engineering decision we make. We work with enterprise customers who manage millions of tables and care deeply about security, auditability, and doing more with less. We uncover hidden data issues in real-time and drive hundreds of thousands of dollars in monthly savings.

The Role

We're looking for a full-time remote Senior Backend Engineer to own significant parts of our platform end to end — from architecture through production. You'll work on systems that process large volumes of audit-log and metadata events, detect issues in production data environments, power our FinOps recommendations, and integrate deeply with GCP. This is a high-ownership role with real influence over technical direction.

What you'll do

• Design, build, and operate backend services in Kotlin (Spring Boot) running on GKE
• Work across our data pipeline: BigQuery, Pub/Sub, PostgreSQL, and GCP-native tooling
• Build and refine the systems behind our cost optimization and observability features
• Manage infrastructure as code with Terraform, and help evolve our multi-tenant, per-customer project architecture
• Uphold and extend our zero-data-access security model — least-privilege access, granular controls
• Contribute to architecture decisions, code reviews, and the technical growth of the team

What we're looking for

• Strong backend experience with Kotlin (or Java with a genuine willingness to move to Kotlin) and Spring Boot
• Hands-on experience running production workloads on Kubernetes, ideally GKE
• Ownership: you can take an ambiguous problem and drive it to a production result
• Solid grounding in GCP — BigQuery, Pub/Sub, IAM, and related services
• Comfort with infrastructure as code, particularly Terraform
• Experience with PostgreSQL and designing data-intensive backend systems
• A security-conscious mindset and appreciation for operating within tight data-access constraints

Nice to have

• Experience with data observability, FinOps, or cloud cost optimization
• Familiarity with multi-tenant SaaS architecture and cross-tenant isolation patterns
• Background working with enterprise customers and their security requirements

Why Masthead Data

You'll join a small, senior team solving genuinely hard problems where the architectural constraints are the interesting part. Your work will be visible to enterprise customers from day one, and you'll have room to shape both the product and how we build it.

CreditBooster.ai's mission is to help every American understand, build, and own their credit. We're an AI-native credit improvement platform, live on the App Store and Google Play, with paying customers and a small remote team across the US and Europe.
 

About the role

We're hiring for a mindset more than for a stack: the engineer who treats a piece of the product as theirs and holds themselves to whether it actually works for the person using it.

That means ownership that follows the experience wherever it lives. A flow starts on a mobile screen, continues on the web, and runs through the API behind both, and we want someone who goes all the way down rather than stopping at a repo boundary. That's usually where the quality of an experience is won or lost.

AI is not a slogan here, it's how we build. Our designer shipped the referral page that's live in production today working with an agent. Our CPO built one of our web apps the same way. The standard we hold ourselves to is not handing a ticket to an agent and approving the result: you plan with it, read the plan properly, push back, iterate, and stay responsible for what ships.

We move fast and we're deliberately not over-gated, even in fintech. Freedom to move, judged on results.

Fully remote, with morning Chicago overlap for standups and demos. Our working overlap is only about four hours a day, so being genuinely effective asynchronously matters here. We'd rather say that plainly than have you discover it in month two.
 

Responsibilities

• Own a product surface end to end: the mobile screen, the web equivalent, and the API behind both, with accountability for whether it works and not just for whether it shipped
• Ship across React Native (Expo) on iOS and Android, our web app, and our Astro landing site
• Cross the boundary rather than filing a ticket at it: Node.js, Fastify, TypeScript, and PostgreSQL are within reach when the surface you own needs them
• Hold the quality bar on what you own, from symptom to root cause to a fix you can prove held
• Use Claude Code, MCP servers, and your own agents to compress engineering work that used to take days into hours, while staying responsible for everything that merges
• Manage releases across App Store and Google Play: EAS builds, rollouts, OTA updates
   

The kind of work you'll see in your first sprint

• Taking one user-facing flow end to end and coming back with your own read on where it should be better, across mobile, web, and API
• A recurring production bug traced to root cause rather than patched at the symptom
• A view on the React Native versus native question, argued from the codebase rather than from preference
   

What we're looking for

• You've owned something, not just contributed to it. You can point at a surface in a product and say it was yours, describe what would have gone wrong without you, and separate what you owned from what your team delivered. This is the single thing we're screening hardest for
• You work across mobile and web. React Native is the centre of gravity, but a surface that stops at the repo boundary isn't owned. You're comfortable in a web codebase and not helpless behind an API
• You're AI-native in how you build. Claude Code or an equivalent agentic CLI is part of your daily workflow. You've built your own skills, agents, or MCP servers that automate real engineering work. You see agents as your primary collaborator, and you can also tell us about a time one was confidently wrong and how you caught it
• You debug for real. You go symptom to root cause to verification, and you know the difference between a bug that stopped reproducing and a bug that got fixed
• You're not attached to a framework as an identity. We may move to Swift. We may not. Either way we want someone who argues it from the codebase and then commits
• You ship without waiting for a spec. Often there's a problem and an owner, not a written specification
   

You may be a good fit if you have

• 4+ years building product software, with real React Native (Expo strongly preferred) shipped to both the App Store and Google Play
• A product area you owned in production. Be ready to walk us through it: what it was supposed to do, what broke, what you changed, and how you knew things got better
• Real web experience alongside mobile: React or a modern web framework, in production
• TypeScript strict-mode discipline
• Enough Node.js and SQL fluency to fix the endpoint behind your own screen
• Effective written communication in English (B2 or higher). Our team works in Russian and Ukrainian internally, but Linear, code, and customer-facing copy are English
   

Bonus

Native iOS in Swift or SwiftUI. Fintech, lending, KYC, or other regulated-domain work. Expo EAS pipeline ownership and store release experience. Astro or comparable modern web frameworks. A public Claude Code skill, MCP server, or contribution to an open-source agent harness. Founding engineer or first-few-hires experience at a small company, where owning the whole thing was the default.

About Fleet Chaser

Fleet Chaser is a U.S.-based B2B SaaS company helping construction, logistics, and service fleets (10+ vehicles) run smoother. Our platform brings everything into one place — real-time vehicle location and status, service data, tasks, time tracking, and reports. We're building products that make fleet managers' and field employees' lives easier every single day.

Now we're looking for a Senior Flutter Developer to join our team and own the mobile side of the product — the app our field employees rely on every day out in the field. We care less about the title on your CV and more about the fire in your eyes, your initiative, and your ability to ship.
 

What you'll do

Our mobile app is how drivers and field crews interact with Fleet Chaser — tasks, time tracking, navigation, real-time updates, and push notifications. You'll build new features, improve existing screens, and keep the app fast and stable across iOS and Android as we grow.

• Develop and maintain our mobile app using Flutter & Dart.
• Build new features end-to-end — from Figma to the stores.
• Improve existing modules — performance, UX polish, and edge cases that come from real customers in the field.
• Integrate REST APIs, real-time updates, and third-party services.
• Work with Firebase — push notifications, messaging, and more.
• Own the release process — App Store Connect and Play Console.
• Collaborate with designers, backend developers, and product managers.
• Write clean, scalable, and maintainable code with proper testing.
• Propose ideas, improve approaches, and help us build not just tasks, but a great product.
   

Requirements

• 4+ years of commercial experience in mobile development.
• 3+ years of hands-on experience with Flutter, with strong command of Flutter and Dart.
• Experience integrating REST APIs.
• Hands-on experience with BLoC or a similar state management approach.
• Experience with GoRouter.
• Experience with Firebase — Messaging / push notifications at minimum.
• Understanding of mobile app release processes (App Store Connect / Play Console) + shorebird
• Strong code review culture (well-described PRs, responsive to comments).
• Mindful use of AI tools. You own everything you push. Review what the model gives you before it lands in main — "the AI did it" is not an answer.
• English level: B1+
   

What matters beyond skills

• Initiative — bring ideas, propose improvements, don't wait for someone to hand you the next task.
• Ownership — take a spec, drive it to the stores without micromanagement. You're responsible for the code you push, including the AI-generated parts.
• Discipline — review your own diffs before they leave your machine. Every commit. Every PR.
• Finish what you start — no features sitting at 80% for weeks.
• Honesty — when something breaks or slips, name it. We all make mistakes; we deal with them faster when nobody hides behind tooling.
• Concrete communication — short updates, on-point questions, no fluff. Remember what you worked on yesterday and be ready to talk about it.
• Pragmatism — balance quality and deadlines, no overengineering.
• Receptive to feedback — engage with code review without defensiveness.
• Product mindset — dive deep into the product, understand the why, not just the what.
   

Nice to have

• Real-time / live-tracking UI experience (location updates, maps, background location).
• Experience with native platform channels or writing small native (Swift/Kotlin) pieces when needed.
• CI/CD for mobile (Codemagic, Fastlane, GitHub Actions).
• B2B SaaS / fleet / logistics domain knowledge.
   

Why Fleet Chaser

• Work on a real product with real users — thousands of active fleet employees and managers in the U.S. market.
• Small, focused team — your work has direct impact.
• You own the mobile app — not a corner of it, the whole thing.
• Culture of value delivery, analytics, and growth.
• Remote-friendly, flexible work setup.
• Direct contact with PM and Backend lead — no layers between you and decisions.
   

Hiring process

1. Screening call with Vlad (PM) — up to 1 hour.
2. Technical interview with the team — up to 1 hour.
3. Probation period — up to 3 months on real product tasks, full pay, mutual evaluation.
