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.

Workload: full-time, remote
Start: asap
Duration: long-term
Location: any
English: B2

Technical requirements (general)
- 3+ years of production blockchain experience in BTC. Multi-protocol experience (strongly preferred).
- Java + Spring Boot + SQL
- Familiarity with test-driven development (TDD) and/or behaviour-driven development (BDD) as working practices, writing tests before or alongside implementation.
- Familiarity with Domain-Driven Design principles.
- Comfortable working in a monorepo structure with shared libraries, cross-squad code visibility, and coordinated CI/CD pipelines.
- Proactive communication, raising blockers, design concerns, and cross-squad dependencies.
- Written and verbal communication in English must be at a professional level.

Technical requirements (specific)
- Deep Bitcoin protocol expertise: PSBT format (BIP-174 and subsequent updates), UTXO management and coin selection algorithms, SegWit transaction structures, script types and descriptor formats (Taproot out of scope).
- Multi-signature coordination: BIP-48 (multi-sig derivation paths), BIP-67 (lexicographic key sorting), P2WSH script construction, PSBT combination and finalisation workflows.
- Fee estimation: Mempool analysis, RBF (Replace-By-Fee) and CPFP (Child-Pays-For-Parent) fee bumping strategies, fee rate prediction.
- Transaction construction: Witness data assembly, BIP-143 (SegWit sighash), DER signature encoding, low-S enforcement. Familiarity with sighash types. SIGHASH_ALL is the production default for custody; engineers should understand the full sighash taxonomy for validation and edge-case handling but implementation focuses on SIGHASH_ALL.
- Transaction lifecycle and remediation: Stuck transaction detection via mempool monitoring, RBF and CPFP execution for fee bumping, handling transactions that remain unconfirmed for extended periods, and managing the operational decision of when to replace vs wait.
- UTXO indexing and balance management: Experience with UTXO set tracking, balance computation from unspent outputs, UTXO consolidation strategies during low-fee windows, and address-level balance monitoring for deposit detection.
- Address management: Gap limit handling for HD wallets, change address allocation from internal derivation branch (m/84'/0'/0'/1/*), address reuse prevention, and descriptor-based address discovery for wallet import and recovery scenarios.
- Chain semantics and failure modes: Understanding of Bitcoin's probabilistic finality (confirmation depth vs settlement assurance), dust output limits and their implications for UTXO management, fee spike behaviour during congestion events (e.g. ordinals, inscription surges filling blocks for extended periods), double-spend detection for unconfirmed transactions, and the operational difference between a transaction that is "broadcast" vs "in mempool" vs "confirmed at depth N." Engineers must understand that Bitcoin has no concept of a "failed" transaction that consumes fees; a transaction either confirms or it doesn't, and unconfirmed transactions can be replaced or may eventually confirm unexpectedly.
- Production experience: Operating Bitcoin custody or wallet infrastructure at institutional scale, not testnet-only or personal wallet experience.

Candidate's responsibilities
Bitcoin wallet management, UTXO handling, transaction construction (PSBT, SegWit), multi-signature coordination, fee estimation.
