Staff Software Engineer - Java | Remote First | Belfast

The kind of role that doesn’t come up often.

Our client is a US-based software company whose platforms sit at the absolute core of how major Academic and Sporting institutions operate day to day. We’re talking mission-critical systems,ones where correctness, reliability, and long-term scalability aren’t nice-to-haves, they’re non-negotiable. The scale is real, the domain is genuinely interesting, and the engineering challenges are the kind that keep good engineers engaged for years.

This is a Staff Software Engineer role with a strong Java backend focus. Remote First, with a Belfast office for those days you want out of the house.

What does Staff actually mean here?

Not a title. A function. You’ll operate across multiple teams as a technical authority, shaping architecture, unblocking delivery, raising the engineering bar, and making systems healthier than you found them. You won’t be doing this through authority. You’ll be doing it through expertise, trust, and the kind of influence that comes from being genuinely good at what you do.

This is high impact. The decisions you make will be felt across the organisation for years.

What you’ll be doing:

• Driving backend architecture and system design across Java and Spring based services
• Leading high-impact initiatives around scalability, performance, and reliability - from whiteboard to production
• Acting as the go-to technical authority on complex domain and system-level problems
• Partnering with Product to translate real business workflows into robust, scalable solutions
• Collaborating with Platform and SRE teams to improve observability and operational maturity
• Tackling legacy complexity head on - architectural debt, performance bottlenecks, the stuff that slows teams down
• Raising engineering standards through pairing, design reviews, documentation, and knowledge sharing

What we need to see:

• 10+ years of professional software engineering experience
• Deep Java expertise with strong command of the Spring ecosystem
• Solid backend focus with real relational database experience - PostgreSQL ideally
• Proven ability to shape technical direction beyond your own delivery
• A track record working in complex or evolving legacy domains
• Strong ownership mindset - you care about what you ship and how it runs
• A clear communicator who builds trust across engineering, product, and platform
• Pragmatic decision making - you balance speed, quality, and long-term system health without losing your mind over it

Bonus points for:

• Angular or modern JavaScript framework experience
• Data-heavy systems, analytics, or performance optimisation background
• AWS, DevOps tooling, or SRE operating model familiarity
• Experience in compliance-driven or operationally complex products

Who thrives here?

You lead through influence, not authority. You enjoy digging into complex systems, asking the hard questions, and leaving things better than you found them. Ambiguity doesn’t faze you. High standards do matter to you. You balance humility with conviction, think beyond the next sprint, and care about building things that are genuinely reliable and valuable to the people using them.

Why Ocho?

We represent the largest selection of technology roles of any recruitment firm in Northern Ireland. If this one isn’t quite right, we’re always up for a coffee to talk through where you want to go in 2026.

Reach out to Ryan Quinn directly on LinkedIn or drop us a message , happy to talk through the detail.

This is a rare opportunity to apply serious data engineering in a domain where latency, correctness, and reliability carry direct commercial weight.
Requirements
6+ years data engineering in production environments; Python expertise - idiomatic, well-tested, production-grade code, not notebook scripts
ETL/ELT pipeline design and implementation at scale; orchestration with Airflow, Prefect, or equivalent; reliability-first mindset including backfill, retry, and exactly-once semantics
Azure data platform - Azure Data Factory, Azure Databricks, Azure Synapse Analytics, Azure Data Lake Storage; infrastructure as code for data workloads (Terraform or Bicep)
Databricks - Delta Lake, Unity Catalog, job cluster vs interactive cluster trade-offs, cost-aware compute management, Spark job optimisation
Relational databases: PostgreSQL at production scale - query optimisation, indexing strategies, table partitioning, replication, schema design for both OLTP and analytical workloads
MongoDB - document modelling, aggregation pipelines, indexing strategy, replica sets; clear judgment on when document vs relational storage is the right architectural call
Containerisation: Docker and Kubernetes-based deployment of data workloads; reproducible, environment-agnostic data infrastructure
Data modelling for analytical workloads - dimensional modelling, data vault, or equivalent; schema evolution, slowly changing dimensions, and downstream impact analysis
Stream and batch processing patterns; late data handling, watermarking, and backfill strategies; throughput vs latency trade-offs in pipeline design
Production data observability - data lineage, quality checks, SLA monitoring, alerting on freshness and completeness; treating data correctness as a first-class concern
CI/CD for data infrastructure - version-controlled pipelines, automated data quality testing, reproducible and auditable deploys
Ability to work directly with quant researchers, risk managers, and traders - translate business requirements into reliable, well-documented data products
Nice to Have
Financial markets data - market data feeds (Bloomberg, Refinitiv), tick data, trade history, reference data, or instrument master management
Apache Spark or Flink for large-scale stream and batch processing beyond the Databricks ecosystem
dbt or equivalent SQL transformation layer; experience building and maintaining dbt projects in a production data warehouse
Event streaming with Kafka or Confluent Platform - topic design, consumer group management, exactly-once delivery guarantees
OLAP-optimised stores - ClickHouse, DuckDB, or equivalent; understanding of columnar storage and vectorised query execution
Energy, commodities, or broader financial markets domain knowledge
What We’re Looking For
You treat data as a product, not a side effect. You know what it takes to make a pipeline trustworthy - not just running, but observable, tested, and recoverable when something upstream changes at 3am. You think in systems: schema evolution, lineage, freshness SLAs, and the downstream impact of every modelling decision. At ETrading , that data is the foundation of billion-dollar trading decisions. You are the reason it is right.
