Backend Engineer: Privacy-First, Scalable APIs

THE PROJECT

Neurode Labs is building brain-computer interface technology that puts privacy, security, and data integrity at its core. We're a small, focused team hiring a backend engineer in Sydney to help us build the infrastructure that sits between thousands of connected devices and the insights they generate.

This isn't a typical backend role. You'll be extending and hardening a production server architecture that manages secure, high-throughput ingestion from thousands of headsets in the field, ensures the integrity, provenance, and privacy of every data packet, and does it reliably at scale, from day one.

WHAT YOU'LL BE BUILDING

In your first six months, you'll take over as our primary backend engineer, extending and hardening the core infrastructure that's already scaffolded. This architecture:

• Handles bursty upload traffic of large payloads from thousands of edge devices in the field
• Enforces strict data integrity and provenance per client: idempotent ingestion, hash-verified payloads, append-only audits
• Handles high-throughput API traffic reliably and safely
• Exposes a validated, bulk-readable data-plane to our ML/data infrastructure
• Correctly handles data-deletion requests end-to-end, including data that's already reached downstream systems
• Gives our team visibility into collection health; device status, data flow, failures; without over-exposing personally-identifiable information
• Is built with privacy and compliance (HIPAA/GDPR) in mind from the ground up

WHAT WE'RE LOOKING FOR

You're a full-stack developer with a clear backend bias. You've shipped systems that handle sensitive data at scale and you're familiar with the practical demands of such systems.

• Strong backend engineering fundamentals, ideally in Go
• Strong server-side programming expertise, particularly Python, is also highly valued and transferable
• PostgreSQL fluency: schema design, query optimisation, data security and integrity
• Experience designing burst-capacity APIs: large-payload uploads, validation-gated ingestion, idempotency, backpressure
• Familiarity with AWS (we may migrate, but you need to navigate what's there)
• Practical exposure to HIPAA and/or GDPR — you know the rules, not just the acronyms
• 5+ years of experience is ideal, but the right mindset matters more than tenure

The background that makes you stand out: hospital systems, fintech, insurtech, defence tech, or anywhere secure + private data at scale was the job (think Signal, Telegram, Apple, healthcare infra, encrypted platforms).

WHO YOU ARE

• You assume you can figure it out, and you're usually right
• You're energised by hard problems, not intimidated by them
• You take ownership seriously; high autonomy and responsibility, you don't wait to be told
• You collaborate well: security doesn't exist in a silo, and you know it
• You communicate clearly across teams: translating technical constraints into plain language is part of the job
• When you spot a problem, your instinct is to solve it, not escalate it
• You learn fast, document well, and leave things better than you found them
• You're based in Sydney and want to work in person with a small, ambitious team

TECH STACK

We're open to informed suggestions on the right stack, as the role is high-ownership. That said, familiarity with any of the following is a plus:

• Go
• Python
• AWS

HOW TO APPLY

Apply via the short survey below. We'll ask you to tell us briefly about a system you've built where security, scale, and data integrity were non-negotiable.
