Enterprise Software
- Bengaluru, India

Senior Backend Engineer (Java) You will work on the settlement and ledger services behind Meridian Exchange's B2B marketplace: roughly 40 million ledger rows a month, Java 21 on Spring Boot, Postgres 16, Kafka for event fan-out. The interesting part is not new endpoints, it is correctness under load — idempotent writes, exactly-once effects on top of at-least-once delivery, and holding p99 write latency under 250 ms as the ledger grows.
- Full-time — hybrid, three days a week on site
- 6-9 years building server-side systems, at least two of them carrying the pager for code you wrote
- Bengaluru, India

Apply for this role The work

What you will do

- Own two or three services outright: schema design, deployment, dashboards, and the runbook somebody else reads at 03:00.
- Move the ledger write path from single-row inserts to batched idempotent upserts keyed on a client-supplied token, targeting 8,000 writes per second sustained on the existing three-node Postgres cluster.
- Design partitioning and retention for tables now past 1.2 billion rows, then run the migration online with no read downtime.
- Review 15-25 pull requests a week and hold the line on what gets merged.
- Share an on-call rotation of one week in six, and write the incident review when it was your service.

You

What we look for

- Deep Java: you can say what allocates in a hot loop, and when virtual threads help versus when they only relocate the contention.
- Working Postgres knowledge — query plans, lock waits, index bloat, and the trade-off between a covering index and write amplification.
- Production experience with a message broker, including what you did the first time consumers fell four hours behind.
- You can argue for the boring option. Most of this codebase should stay legible to whoever joins next year.
- Comfortable talking directly to a client's engineers rather than through an account manager.

- Full-time — on site

Platform Engineer, Kubernetes Atmora runs more than 40 client workloads across EKS and AKS, from a nine-node cluster carrying Kestrel Industrial's shop-floor telemetry to a two-region active/passive setup for Corvus Logistics. You will own the internal platform those delivery teams deploy onto: the Terraform module library, the Argo CD app-of-apps layout, and the paved path that takes a service from merge to production in under 12 minutes.
- London, UK
- Full-time — London office,



with four to six client-site days a month across the UK and EU

Principal Solutions Architect Most of our UK work is legacy modernisation for regulated businesses: Cordage Bank moving a 22-year-old core banking periphery off a shared Oracle schema, Aldridge Risk replacing an overnight batch that had grown to 9 hours and 40 minutes against a 6-hour window. You will run discovery, decide the migration shape, and stay accountable for it once delivery starts — not hand over a slide deck and leave.

- Full-time — hybrid, three days a week on site

Machine Learning Engineer Three active workstreams: price-anomaly detection over Northwind Commodities' trade blotter, document extraction for Orbit Supply covering roughly 30,000 pages a month of bills of lading and purchase orders, and retrieval over a contract library of 140,000 documents. Every one of them starts with an evaluation set, not a model. If you cannot measure it against a labelled sample the client agrees with, we do not ship it.
